Chip tuning of VAZ 2114, 2113, 2115: is it better to do it yourself or have it done at a service center?

Mostly young car enthusiasts prefer to tune their steel horse. The desire of young people for more often pays off if you approach the improvement procedure wisely, and not at random. The older generation prefers reliability, relying on factory settings, even if the car is not as fast as we would like.

In this article we will introduce you to chip tuning of car brains, and more specifically, how to flash the VAZ-2114 firmware yourself on an 8-valve injection engine.

Content

The internal combustion engine control unit is needed to set the basic settings. Car manufacturers set settings without taking into account weather conditions, fuel quality and driving style. In other words, the internal combustion engine may perform poorly not due to a malfunction, but due to incorrect adjustment, which is set through the control unit. That is why many people have a question about whether they should carry out chip tuning of the VAZ 2114, how the behavior of the car will change if such work is carried out, and whether it is possible to do it yourself.

Recently, the tuning method in question has become quite popular, due to the simplicity of its implementation and the real results that can be achieved.

After the emergence of a sufficient amount of equipment for diagnosing internal combustion engines before and after chip tuning, various studies were carried out, which indicated the following: there are more advantages to this method of changing engine operation than disadvantages.

Tuning an 8 valve engine “with split gear”

The split, that is, adjustable gear was not used in the last project. It is better to install it on “non-plug-in motors”. Setting method: 1.
The moving and fixed parts are marked with a mark, the same as on a standard pulley;
2.
Installation is carried out in the usual manner, aligning the crankshaft and timing mechanism according to the marks (as when replacing a belt), you should also remember about the correct tightening torque of the belt;
3.
If in the 4th cylinder the intake and exhaust valves are not open “to the maximum”, we carry out the adjustment: loosen the outer screws, and, holding the outer part of the gear, set the camshaft correctly. Tighten the fixing screws.

Advantages of tuning and possible risks

Before deciding to carry out chip tuning of the VAZ 2114, many people wonder what will change after it is completed. The advantages of this method of changing engine operating parameters include:

1. Significant increase in power. It should be noted that higher engine power is needed not only for lovers of high speeds. For example, when entering the oncoming lane, the power reserve will be useful. In some cases, you can increase the power by 25%, for which you just need to change the chip firmware. Experts recommend carrying out firmware that increases power by no more than 15%, since increasing this indicator leads to a significant increase in the load on the engine. 2. If for some people the driving performance of a car is important, then for others saving on fuel. Correct firmware can reduce fuel consumption by 3-5%. Considering the established cost of fuel, such a reduction in consumption will allow significant savings. In some cases, chip tuning is carried out in order to switch to fuel with a lower octane rating, which costs less. 3. More and more often there are cars that display engine errors on the dashboard. This phenomenon is a reason for diagnostics, but in some cases you simply need to remove these errors. This can be done through chip tuning.

The above list determines that chip tuning of the VAZ 2114 is carried out to increase engine power or reduce its consumption. In rare cases, a change is made so that it is possible to use fuel with a low octane number, since the internal combustion engines installed on this car are already unpretentious to the quality of gasoline.

However, there are also disadvantages to the modernization method under consideration. These include:

• If the service is provided poorly, there is a possibility that the unit will fail. Its cost is quite high, and repair work is also not cheap. The control unit can only be damaged if serious mistakes are made. Therefore, the work should be trusted exclusively to professionals who have extensive experience.
• By setting the maximum possible values, you can significantly reduce the engine's operating life. Note that this argument is not a theory, but a proven truth. As practice shows, the resource decreases by no more than 4%. However, this number does not include cases where serious errors were made during the firmware of the control unit.
• If tuning is aimed at increasing power, then mistakes made can cause a significant increase in appetite - in some cases, consumption increases by 1/5.
• The disadvantages include the cost of performing such work. At the same time, we note that there are quite a lot of offers that are attractive in price. In most cases, the price is reduced due to poor quality work. Chip tuning of a VAZ 2114 from a specialist will cost several tens of thousands of rubles.

The information provided in this section determines that chip tuning can significantly improve the driving characteristics of the car. However, the work should be trusted exclusively to professionals, since otherwise the work performed will lead to very serious problems.

Factory specifications

Electronically controlled distributed injection

Zero resistance filter

The concept of “tuning” appeared in Russian everyday life several years ago, and translated from English meant tuning or adjustment. Today it is:

• improving the appearance of the entire car;
• change in its power;
• conversion of factory settings, etc. This procedure allows you to make the car unique and should be carried out according to the personal requests of the owner.

Most car enthusiasts consider this a whim, but drivers who have tuned the VAZ 2114 engine say that the car began to behave differently, this is especially noticeable at lower speeds. The power of the engine increases, the car picks up speed better, acceleration to 100 km/h occurs faster, and the driving dynamics become greater. This is a huge advantage when overtaking on the highway, when you need to give sharp acceleration, as well as in the city when maneuvering in traffic jams.

Engine tuning theory

The concepts of “engine tuning” and “budget tuning” are incompatible, so I have almost nothing to say here. Of course, the most effective measure in engine tuning is to increase the displacement. Only this gives a simultaneous increase in power and torque throughout the entire speed range - from the modified 1.8-liter VAZ-2112 engine you can get a torque of more than 20 kg/m, and the maximum thrust of 10 kg/m of the standard 2110 engine can be curbed already from 1500 rpm min! Another measure is to install various types of compressors, replace the fuel with a more “flammable” one (nitromethane, i.e. alcohol), supply an additional fuel oxidizer (nitros), but this is expensive. And even the little that can be done with a reasonable investment requires the hands of a master and a lot of experience. Therefore, I will dump here not only the engine itself, but also the power supply, ignition and exhaust systems. The timing mechanism
- the gas distribution mechanism - is the only place available for budget tuning where you can extract an “increase”. Theory. The camshaft determines the valve lift (and the higher it is, the better - throughout the entire engine speed range), as well as the time and duration of valve opening. Unfortunately, we cannot raise the valve as much as we want: the valve springs will pick up the gaps between the coils and break. To raise the valve even higher, modifications to the cylinder head are required - first, lower the valve seats (for example, for MM54 - by 1 mm), then more radical measures - replacing springs, pushers, etc. - not budgetary. Therefore, for the 2108-2111 engine, the maximum permissible valve lift is 9.7 mm, i.e. without modifications to the timing belt, you can install the “Nuzhdin” camshaft or their equivalent.

Tuning camshafts

A few words about the time and duration of valve opening - the width of the phases. The higher the engine speed, the earlier the intake valve must be opened before top dead center (TDC) and the later it must be closed. This is necessary to provide the mixture, which has high inertia at high speeds, with the opportunity to fill the cylinder as completely as possible and allow the burnt charge to escape. Accordingly, in the exhaust phase it is also necessary to act proactively, so that by the time BDC is reached, when the hot mixture no longer produces work, let it begin to leave the cylinder, and also hold the exhaust valve open after TDC in order to remove as much exhaust gases from the cylinder as possible. . At low speeds, this leads to the fact that exhaust gases that have not yet fully escaped enter the intake system, preventing fresh mixture from entering, which reduces traction at the bottom and makes idle very unstable (therefore, on shafts with wide phases it is necessary to increase the idle speed) . At high speeds, overlapping the intake and exhaust phases allows for a more continuous flow of gas through the CPG and, accordingly, burns more mixture and significantly increases engine performance. The relationship is nonlinear: a gradual increase in phase overlap first gives an increase in torque at high speeds, gradually shifting the maximum to higher and higher speeds. After a certain point, a subsequent increase in phase overlap has the opposite effect - a drop in power and torque even at high speeds. If we are talking about a two-shaft engine. then the master’s task is to find a position of the shafts at which we get maximum torque at the highest possible speeds, and thus obtain maximum power. In the case of a single-shaft engine, there is no need to think about this - the phase overlap is provided by the manufacturer, you only need to accurately set the position of the camshaft relative to the crankshaft, and the overlap can only be changed by changing the shaft. To obtain “tractor” traction, you need a shaft with minimal phase overlap and maximum valve lift. We will get more traction at low speeds, which is very important for a city with constant traffic jams.

The technical characteristics of the 1.6 liter engine are not very different from previous versions. Compared to the one and a half liter engine, this engine has become more powerful by only 4 hp. Apparently, AvtoVAZ designers, in their pursuit of increasing engine life, completely forgot that they also needed to increase power. Therefore, happy car owners themselves are trying in every possible way to “add more horses” under the hood. There are cases when craftsmen managed to squeeze up to 140 hp. from a VAZ 2114 engine, engine tuning added power almost twice as much as the factory specifications show. But as power increases, engine life decreases. Therefore, we will talk about how you can increase power and at the same time shorten the life of the VAZ 2114 engine as little as possible.

It's no secret that in its standard, that is, in serial form, the engine does not develop all the power it is capable of.
You can configure the firmware in a new way, but you won’t be able to significantly change the load curve without reducing the environmental class. You can buy a "racing camshaft" to install in place of the stock one. But then the firmware will have to be changed to accommodate the new phases... Let's consider what happens if we use only accessible tuning methods. Let's say right away that on the VAZ-2114 hatchback the increase in power can be 20% or even 25%, and we are talking about only 8 valves. There is no need to bore the valve channels. During tuning, the engine 21114 (1.6 l) was modified. List of works:
• Boring of seats along the internal diameter, which is equivalent to enlarging the valve;

Valve seats, VAZ 21114 engine

• The channel necks also had to be bored out a little. Thin duralumin plates were installed, which allowed the springs to be loosened by 1.5 mm; • Standard valves were replaced with lightweight ones; • The guide bushings were machined from special brass;

• A split gear appeared in the design;

Tuning split timing gear VAZ 8 valves

• Valve cotters were replaced with imported ones just in case; • A shaft with “narrow phases” was installed: exhaust – 66 degrees, intake – 70, opening angles – 246 and 250 degrees, respectively. Valve travel is 9.5 and 9.6 mm. Our new engine remains “not plug-in” - the valves do not reach the pistons. When tested on a bench (the sensors were turned off), the result was not impressive.

Checking without adjusting the ECU

If you install the engineering firmware, you can select the parameters “from start to finish.” And then the picture looks better...

All sensors, including the lambda probe, were connected in the latter case. We managed to get 96 “forces” at 5300 rpm!

Why do you need chip tuning?

Today we will talk about chip tuning for the VAZ 2144, which affects the behavior of a passenger car on the road, changes the dynamics and declared engine power, and also allows you to use the unused “talents” of the car. Such changes can only be made in those machines where “brains” or an electronic control unit with a microcircuit are installed. This type of updating your iron friend is the most popular and widespread. After this, engine operation becomes more forced.

There are a lot of specialists who advertise reprogramming services, but here it is worth remembering that flashing the VAZ 2114 firmware should be performed by professionals for whom your order is not the first “hack job”. You also need to be sure that in addition to knowledge and skills, they also have the necessary equipment - a programmer. Improperly performed work will not only not improve the vehicle's performance, but may also require replacement and repair of electronic systems, and therefore incur additional costs.

Engine ECU VAZ 2114

The average price starts from 1500-2000 rubles and depends on the year of manufacture of the updated vehicle, but it is possible to carry out chip tuning of a VAZ 2114 with your own hands. In addition, to improve performance, there is no need to replace the engine with a turbocharged one, which also reduces costs and does not require re-registration of the vehicle's passport, and also allows you to easily undergo annual technical diagnostics (inspection) of the car.

Flashing changes the parameters set by the manufacturer. But its task is not only to change, but sometimes to remake poorly configured data. Thanks to this, control and adjustment of fuel supply, ignition systems, air supply and other modes become more advanced and can already comply with Euro 2 and 3 standards, which is bottled in our gas stations. Reprogramming also helps very well when the catalytic converter breaks down, eliminating this error.

How to properly perform chip tuning with your own hands?

To update the program qualitatively, you need to decide what tasks you set for yourself.

1. To improve all characteristics, you need not only to flash the brain, but also to do additional actions, such as replacing the air filter. This will increase the engine power of your car by 5-10% at once. The first visible drawback of such improvements is increased fuel consumption, but the figures level out after some time.
2. After replacing the filter, the panel with microcircuits is removed from the electronic unit, which is connected to the programmer, which enters the required information and updates the software.
3. These are minimal changes, and after installing the electronic board in place, you can try another power of your “swallow”.

It is also worth considering that chipping allows you not only to increase power, but also to set the engine modes to economical, starting or transitional. As mentioned above: it all depends on the desires and capabilities of the client.

How to tune a VAZ 11183 engine

It is clear that a mandatory step in tuning the 11183 engine will be replacing the ECU. It’s simple: the standard M74 block cannot be flashed, but “January 7.2” is a good and time-tested solution. You will also have to abandon the “E-Gas” option, which means replacing the throttle assembly and receiver.

Everything I had to throw away

The intake tract parts were borrowed from the 2111 engine. A cable pedal was installed, and the engine began to look human.

Engine VAZ 11183

Everything works well with the “January” controller, but standard firmware is not an option if the camshaft has been replaced. And it, in turn, has the following parameters: • Release phase width – 104; • Intake phase width – 109; • Opening angle at the outlet – 272; • Opening angle at the inlet – 268; • Valve stroke (exhaust/intake) – 9.5/10.1 mm. After installing the new shaft, the motor became plug-in. However, on the 2114 hatchback, increasing power almost always comes with a compromise. In this case, we had to sacrifice reliability. What has improved: • Maximum torque increased by 14 N*m; • Power also increased – the limit of “90 horsepower” was passed. By the way, any tuning leads to a decrease in durability. Make a choice.

Where can I find the programmer?

The programmer can be bought in many online stores with delivery, and its task is not only to flash the car’s brains, but also to diagnose engine problems, as well as remove errors that arise. Their cost varies, as do their functional characteristics, which depend on your desires and requests. But for the sake of one-time manipulations with the engine, it is not worth purchasing it; it is better to contact car workshops and auto electricians, and better on the recommendation of friends. It would also be a good idea to read reviews about automotive specialists and companies on specialized forums. A competent specialist may advise changing the settings for the toxicity of exhaust gases, as well as converting the ignition system timing parameter.

If you are still asking yourself the question “Is it worth making changes to your car or not?”, then the answer is a clear “YES”. And it’s better to start with chip tuning of the VAZ 2114 engine. With small financial and time costs, your iron horse will become 15 percent faster in total and will delight you with fast acceleration. When the car is fully loaded, it becomes easier to maneuver, and dynamics and acceleration increase. The only advice: you should not make engine improvements if the car is still under warranty and service, as this may reduce or void the warranty period.

Why do you need to do chip tuning?

Regardless of whether you have a foreign car or a VAZ, the factory firmware of cars is not ideal and needs to be improved. Also, after a breakdown of parts such as a catalyst, oxygen sensor, etc., it is easier and cheaper to flash the brains than to spend money on repairs. Also, among the factory firmware there are very often defects - the car behaves strangely at idle, low dynamics, failures in the engine.

Some cool foreign cars are not designed to use our low-quality domestic fuel, and only chip tuning can cure this.

What does chip tuning give and what are its results?

Firstly, this is getting rid of glitches and bugs of the factory firmware. Secondly, depending on the client’s needs, the following results can be achieved:

1. smooth and smooth engine thrust without dips;
2. increase in engine torque power (usually from 7% to 15% on VAZs);
3. improving vehicle dynamics and acceleration;
4. disabling additional sensors that choke the engine: lambda probe, catalyst;
5. transition from EURO-4 toxicity standards to EURO-3, from EURO-3 to EURO-2 (disabling dk);
6. setting up smooth and uniform operation of the automatic transmission;
7. reduction in fuel consumption.

Chip tuning VAZ 2114, how to reduce fuel consumption

The second wind of the ninth family Lada-Samara 2, with the model range 2113, 2114, 2115. The updated models came in stages: 2001 - 2115, 2003 - 2114, 2005 - 2113. From 2001 to the end of 2005. Lada-Samara2 cars were equipped with an 8-valve power unit (2111), a displacement of 1.5 liters, a maximum power of 77 l/hp at 5400 rpm, a maximum torque of 115.7 Nm at 3000 rpm. Read more about this engine in the article about engines on our website.

Since the end of 2006 - a new 8-valve power unit (11183), a displacement of 1.6 liters, a maximum power of 80.9 l/s at 5200 rpm, a maximum torque of 120 Nm at 2500–2900 rpm.
Read more about this engine in the “Useful information” section about engines on our website. Since 2009 - a modern 1.6 liter, 16-valve engine with a maximum power of 98 l/hp, at 5600 rpm and a maximum torque of 145 Nm at 3600 rpm, non-serial production of SUPER-AUTO CJSC. Read more about this engine in the article about engines on our website. The ECM is undergoing major changes and goes through almost all stages of evolution. From 2001 to the end of 2004, 55-pin control units were installed on Lada-Samara2 cars, namely M154, Ya5.1, VS 5.1, with environmental standards of both Russia 83 (without DC and adsorber), and Euro-2 (with DC and adsorber). Since the end of 2004, all cars have been produced with Euro-2 environmental standards, and at first they were produced with a Bosch 7.9.7 ECU, then the domestic manufacturer quickly caught up with the January 7.2 ECU, but due to the rush, the firmware was not always finalized, so new production versions appeared, hence the cars were not only stifled by new environmental standards, but also had errors in the settings, such cars had to be recalled by official services and the defects eliminated, but in practice these were isolated cases. Disadvantages of this system: incorrect temperature conditions, twitching, insufficient elasticity and high-torque. This car can be considered one of the most problem-free, but it is better to eliminate these shortcomings. In 2008, all cars began to be equipped with two DCs and comply with EURO-3 environmental standards, and the new domestic M73 ECU (depending on the car). Some models received incorrect software and as a result had shortcomings, such as serious failures, unstable idling, unstable speed in transient modes (gasping), misfires from the rough road sensor, as a result of which the catalytic collector is destroyed, increased fuel consumption, mediocre engine elasticity , poor dynamics - all this can be treated by modifying the ECM. In 2011, the law forces automobile concerns to present surprises in the form of new engine management systems, the relatively new BOSH M74 ECU (on 8-valve engines) and Me1797 on 16-valve engines. engines, capable of throttling engines up to Euro 4/5 Environmental Standards, a feature of these systems is an electronic gas pedal. The problems of cars of 2011 have already been studied, using the example of the UAZ-Patriot, which has been equipped with ECU data since 2008, so it is really possible to successfully modify the ECM even for the newest cars. Calibrations have successfully passed tests, services for the modification of the ECM of cars produced in 2011. We deliver successfully! There is no point in writing about each system, but it is possible to indicate general points. None of the systems were developed specifically for the engines of the Lada Samara, but were adapted to them through the efforts of engineers; there are several software, so the plant tried to eliminate the shortcomings as far as possible, but it is far from ideal... The problem with this is the lack of ability to configure the correct mixture due to environmental standards and average settings designed for a very large circle. We customize everything for a specific driver. It’s a vicious circle with environmental standards! The AUTO063 company is constantly improving the provision of diagnostic and vehicle tuning services. In the period from the end of 2004 to 2007, I personally used car 21140; the firmware for the 1.6 engine was tested on a Lada-Kalina purchased later; in mid-2007, everything was finalized to the smallest detail! The result is impressive even for those who have previously worked with us; by the way, our clients receive a free update. So, what will happen after the ECM is modified:
➤ Software removal of the rough road sensor, removal of misfires;
➤ Removing dips during sharp pedaling; ➤ The accelerator pedal will be very soft and informative; ➤ Removing jerks when switching from first speed to second (there are 2-3 jerks before modification); ➤ Stabilization of speed in all modes; ➤ Improved traction at the bottom; ➤ Improved traction at low, medium and power loads; ➤ Improved elasticity: now you don’t have to switch to a lower gear to drive uphill, now the car can not only not lose speed, but also gain it and, accordingly, increase speed; ➤ Improved dynamics on the track, the car is simply different, the maximum speed has been increased; ➤ Removing jerks when closing the throttle suddenly; ➤ We remove the control of the second DC, which allows you to remove the catalyst, and leave the second DC as a “spare”, because it is absolutely identical to the first; ➤ For vehicles with excessive fuel consumption, measures will be taken to reduce consumption; ➤ Changing winter startup on problematic software; ➤ Improved engine warming up at low temperatures; ➤ Increase idle speed; ➤ Changing the characteristics of the RDV, which will allow the system to maintain speed more evenly; ➤ Almost all system calibrations are affected; ➤ For vehicles with air conditioning, the influence of the air conditioner is minimized. ➤ Fuel consumption will NOT increase. After modification, the use of 92 grade gasoline is strictly prohibited, only 95! Anyone who disagrees with my position on the use of high-quality fuel should read the Articles on Gasoline section. The firmware identifiers remain factory; the dealer on warranty vehicles will not see that the car has been modified. Before launching any car brands into a “series” of services, Auto063 specialists, together with outside service station employees (well-known calibrators in the Russian Federation), did a lot of work to study problems on all serviced car brands, with all types of power units and types of transmissions. Oddly enough, many cars, regardless of power and engine type, have similar problems that do not allow the consumer to use the full potential of a modern engine. What shortcomings were noticed: The car came from the factory, very sluggish!
This can be fixed, please contact us! Weak response of the accelerator pedal (unpredictable response, lack of smooth transitions, adequate acceleration dynamics);
mediocre low-end traction; The transition to the power mode is set up in a rather unique way (only “pedal to the floor” helps), but I would like to get that same declared power earlier; when the air conditioner is turned on, the power drops; fuel consumption increases sharply and unjustifiably, the car does not drive as much as it consumes; insufficient smoothness in some modes; a unique switching algorithm for versions with automatic transmission (often you have to switch to a lower gear); jerking when switching to manual; poor cold starting; RPM fluctuates when warming up or idling; and that’s not all... What has been changed:
Dips and “turbo lags” during acceleration have been removed;
increased the overall dynamics of the car; improved elasticity under light and partial loads; expanded the operating range by increasing torque and shifting its peak to lower speeds; in certain modes, the restrictions on the maximum realized torque have been raised; measures have been taken to reduce fuel consumption; changed the automatic transmission operating algorithm (shifts will be smoother and less frequent); made changes to the maps of fuel supply, fuel supply, and their corrections. We optimized the algorithm for determining Hi-Octan -> Low-Octan (the algorithm for selecting the POP depending on the quality of the fuel), and changed the logic of the “mode manager” (you need to press the pedal less to obtain the desired dynamics). Made changes to the instantaneous model calibrations; optimized the operation of the E-GAS system (clear response to pedaling), increased the fuel cut-off speed while driving; in the ECUs responsible for the operation of turbocharged engines, the calibrations responsible for the boost were additionally changed (at the same time, this does not affect the life of the turbine, engine, transmission, or attachments, but the dynamics change radically); the problem with the so-called “boom tuning” was solved, when when pedaling a pop was heard with a loss of power and the “Cheeck” light came on; the calibrations responsible for extreme load conditions have been changed (now the air conditioner has virtually no effect on the dynamics); on problematic software, the calibrations for winter start, warm-up and idle modes have been changed (the speed will no longer fluctuate). It is also possible, if desired, to disable the second oxygen sensor to remove the catalytic converter, catalytic converter or particulate filter. It is also possible to disable the EGR valve and similar systems. What are the output results:
• Increase in torque on atmospheric gasoline internal combustion engines from 10 to 20%; • Increase in power on atmospheric gasoline internal combustion engines from 3 to 9%; • Increase in torque on turbocharged gasoline engines from 15 to 25%; • Increase in power on turbocharged gasoline engines from 7 to 15%; • Increase in torque on turbodiesels from 15 to 40%; • Increase in power on turbodiesels from 10 to 30%. It is difficult to display in percentages the results that the car owner feels, especially for gasoline and diesel turbo engines. After modification, it is necessary to use fuel of at least Premium 95 for gasoline engines, and high quality diesel fuel for diesel engines. In individual cases, it is possible to adjust to 92, but the result will be less noticeable.

What firmware are the best?

Today, some of the best firmware are the creations of PAULUS. Chip tuning by Paulus has very good reviews throughout Russia. Paulus creates firmware not only for VAZ, but also for many foreign cars. Get your car flashed only from official Paulus representatives in your city. Only official representatives give a guarantee for the firmware and install it “directly”. Avoid dubious would-be diagnosticians who just want to rip your money off.

Recently, an increasing number of car enthusiasts are interested in such a subject as upgrading their car - and this is not surprising, because everyone wants to customize the car “for themselves”, to make it unique. One of the options for such changes is chip tuning for the VAZ 2114. It allows you not only to give individual features to the car, but also to make its driving characteristics much better than the factory ones. We’ll talk about what it is in today’s article.

What does chip tuning give?

Chip tuning is a change in the basic settings of the electronic control unit to more modern (and therefore more advanced) ones. A similar firmware of a VAZ 2114 is performed without any physical intervention in the ECU, only by programming methods.

Thanks to its implementation, you can get:

• increase in engine power up to 25%;
• increase in torque up to 15%;
• reduction in fuel consumption up to 12%;
• reduction of exhaust toxicity;
• facilitating cold engine starting.

As you can see from this, flashing the brains of a VAZ 2114 is an extremely desirable and even economically beneficial procedure for the car owner.

What is firmware?

What is ECU firmware, how to properly reflash such a device when connecting it to the diagnostic connector with your own hands, what programmer and equipment to use for chip tuning? ECU reprogramming is the process of reconfiguring the engine control unit with all calibrations. The firmware is a set of programs recorded in the memory of the engine control unit, with the help of which its operation is controlled.

If the driver decides to perform chip tuning of the car, the ECU is reset. Tuners interact with elements of the engine control unit (calibration) to control the combustion of the combustible mixture and the operation of all unit regulators.

In some cases, when performing chip tuning using the editor, only the program code is changed. But this happens less often than making changes to the calibration. The control unit firmware can be located either inside the processor or on an external board; it all depends on the engine model and vehicle.

ECU re-pinning by masters in the field of chip tuning can be done using various programmers and equipment. The price of such equipment for chip tuning is high, but with the use of such programmers it is possible to add serious adjustments to the operation of the unit. The chip tuning itself with such equipment with pinouts, calibration and programmers can be of higher quality if the flashing is carried out by a qualified technician.

Note that the type of interface used for chip tuning for firmware does not matter. The specialist must be sure that, if necessary, he will be able to reprogram the device and restore the factory settings of the engine control unit programmer. In addition, we must not forget that every year automobile manufacturers improve their anti-theft systems. And this complicates the work of a chip tuning specialist. On most cars manufactured before 2008, with chip tuning with pinout and calibration, it is not possible to reconfigure the device without dismantling it.

Screenshot of car computer firmware

What kind of firmware are there?

Today there are a huge number of different manufacturers of equipment programmers for flashing engine control devices. The most famous and in demand are American and German manufacturers, but in Russia, the number of companies producing programmers has recently been growing. This is due to the spread in the territory of the former CIS countries of vehicles with turbodiesel and injection internal combustion engines, as well as modern engine control units. But as a result of the fact that automobile manufacturers initially equip cars with modern anti-theft protections on the assembly line, domestic equipment programmers sometimes do not allow reflashing the ECU.

What does flashing do?

If the chip tuning of the equipment was carried out correctly, then you will feel changes in the operation of the engine immediately, on your first trip. A competently carried out chip tuning procedure allows you to achieve smooth and smooth operation of the unit, as a result of which driving becomes more comfortable. In addition, calibrating and reflashing the engine control unit will increase the engine power and also increase its torque.

These parameters help improve vehicle dynamics, and in some cases you can even achieve a reduction in fuel consumption. But there is no need to chase increased power and constantly reconfigure the equipment, as this can lead to undesirable results. Moreover, do it yourself without experience, as the computer may fail.

Preparing for chip tuning

Before you start an “electronic upgrade” of your car, you should perform several important operations, which are the key to ensuring that the tuning will only be beneficial and will not cause any harm to the car, namely:

• check the condition of all, and especially heavily loaded components and assemblies. After all, the main goal of reconfiguring the ECU is to increase power and torque, as a result of which heavily worn parts can become damaged and even fail;
• clarify whether reprogramming is possible in your case. The fact is that not all programs allow you to establish such “feedback” and make changes, which means that trying to change them is useless;
• find out the value of the inherent potential. Thus, when programming the ECU at the factory, manufacturers in the vast majority of cases leave a “reserve” of power, as a result of which the engine does not operate at full strength and has hidden capabilities, which reprogramming is intended to extract. In the same case, if the engine is already working at its maximum from the factory, no amount of chip tuning will help.

WHAT RESULTS CAN YOU GET?

• Reflashing can give a power increase from 5 to 25% and an increase in torque up to 15%.
• Due to the increased engine power, fuel consumption is noticeably reduced - up to 12%. But after chipping, the car begins to consume higher quality gasoline and oil. For example, before reprogramming the ECU, your car consumed 92 octane gasoline; after the firmware, the engine starts running at 95 octane, which also has a positive effect on the power characteristics of the engine. An increase in gasoline consumption is only possible if the driver begins to use the increased engine power to the maximum. And this doesn't happen often. Many drivers carry out such brain reprogramming precisely in order to save gasoline.
• Reconfiguring will qualitatively improve the operation of the fan, which will affect cold starts, thereby reducing the acceleration time.
• As a result of tuning, the toxicity of exhaust gases is reduced.

In general, high-quality and competent chip tuning will optimize the operation of all engine components, making driving this car more comfortable and less expensive.

What is needed for electronic tuning

The main “tools and devices” that will be needed when performing firmware for the VAZ 2114 8 valves are:

1. Programmer.
2. Disk with the required firmware version.
3. PC or laptop.

If there are no problems with the last two points, then the programmer will need to be purchased. This can be done either in a car store (if not in stock, then order it) or via the Internet. It is worth considering that this device is far from cheap, and buying it for a single use is not at all profitable.

The best option would be to purchase it together with other car enthusiasts or contact a specialized workshop, where all reprogramming can be performed by professionals.

How to do chip tuning yourself

As already mentioned, the best option for tuning is to contact a car service center. There, specialists will be able to accurately change important settings of your ECU without damaging the operation of other vehicle systems.

If you really want, you can try to flash the firmware yourself - to do this you will need to connect the PC to the ECU via a programmer and set the required settings in the working window of the screen (on different machines, electronic units can be programmed using different programs, each of which has its own operating features; according to For this reason, it won’t be possible to give any specific advice here on how to flash a VAZ 2114 step by step).

The only thing you should remember when performing independent chip tuning is the relationship between all operating parameters of the engine. So, by increasing its power to the maximum possible value, we will get a significant increase in fuel consumption, and along with it - increased toxicity.

It should be said once again that if you are completely ignorant of programming and have only basic PC knowledge, then doing chip tuning yourself is absolutely not worth it. After all, the result obtained can be not only zero, but also negative.

FIRMWARE WITH YOUR HANDS

Do-it-yourself chip tuning can be done if you are versed in electronics. To do this you will need

• laptop;
• licensed firmware recorded on disk;
• programmer, that is, a device that will rewrite the ECU chip.

Automotive control units operate according to various programs. The most famous of them are Delphi, Bosch and Valeo. It is important to know which program is in your ECU. A professional programmer can independently change the settings in the car brain. All you need is the ChipTuningPRO software, with the help of which changes will be made to the car electronics settings. Less advanced drivers can use a ready-made program to flash the brains of a VAZ 2114 with their own hands. For this you will need a programmer. This is a device into which the control unit microcircuit is inserted. Expensive programmer models sometimes have up to a dozen different microcircuits. Using this device, you can enter the parameters of existing firmware, and even, if you have the appropriate knowledge, interfere with closed processes.

ChipTuningPRO at work

Important. If you do not have basic programming skills, you should not attempt chip tuning yourself. If a person has never held a hammer in his hands, then he will not be able to hammer a nail into a pine board. Electronic equipment is not a hammer, and requires much more knowledge and skills.

Disadvantages of ECU flashing

As mentioned above, an electronic upgrade of the control unit has not only a large number of advantages, but also certain disadvantages that should be kept in mind.

These may include:

• increased load on the engine and adjacent units;
• increased fuel consumption;
• increased toxicity of exhausts;
• rapid wear of parts;
• refueling a car with more expensive fuel.

True, it should immediately be noted that most of these shortcomings (for example, excessive fuel consumption) can only appear as a result of independent and, at the same time, not very successful tuning. When performing flashing at a car service center, technicians will be able to set the operating parameters of the engine to the maximum so that they do not “overlap” each other and do not interfere with themselves.

Achieving similar results at home and in the absence of the necessary skills is extremely difficult. As a result, the by-products will be increased toxicity and waste.

Speaking of the latter, it should still be noted that when the engine power is set to maximum, the consumption will increase in any case. The only thing that can be different is the number by which it changes. If, on the contrary, you want to reduce fuel costs, then when carrying out chip tuning, you should focus on this. True, the power characteristics of the engine, on the contrary, may decrease.

How not to increase the power of the VAZ 2114!

✔ Do not attempt to bore channels. This operation can be performed in the absence of ball cutters, but in garage conditions nothing will work even with cutters. The bottom line is that the accuracy of the cutter installation is important - the error should not exceed 1-2 microns. ✔ As you can see, on the stock VAZ-2114 hatchback the increase in power was 24%, and this is without installing a “chandelier”, “improved exhaust” and other expensive elements. ✔ There is no point in buying a “racing camshaft” without having the appropriate tuning firmware.
