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.
Firmware for VAZ 2114
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.
Chip tuning VAZ 2114
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.

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.
ECU VAZ 2114
In addition to the points listed above, you should also take into account the fact that before starting the upgrade, it is highly advisable to replace all filters in the car (and especially the air filter). After all, only performing programming on a completely “updated” machine will give the maximum result.
It is also worth remembering that after chip tuning the car will need higher octane fuel. So, if before the upgrade the engine was running on 92, then after it is completed you will need 95.
16-valve engine for the "seven"
The VAZ 2107 is equipped with an 8-valve power unit from the factory. Of course, one of the easiest tuning methods is to replace it with a 16-valve engine. Traditionally, the engine from the VAZ 2112 is chosen, since it is almost identical in size to the engine from the VAZ 2107 and meets all the requirements for power and efficiency.
Installation of a 16-valve engine on a “seven” is carried out according to the following algorithm:
- Prepare the motor for installation. To do this, you need to remove the flywheel and grind the crown from the inside. Turning is necessary so that the starter parts are more easily connected to the flywheel clutch. In addition to turning, you will need to replace the input shaft bearing with a bearing from 2112, otherwise the new engine simply will not fit into the seat.
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:
- Programmer.
- Disk with the required firmware version.
- PC or laptop.
ChipTuningPRO at work
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.
Flashing the VAZ 2114 ECU
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.
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.
Injector advantages
- more accurate fuel dosing;
- fuel burns better, engine efficiency is higher;
- gasoline costs are reduced;
- environmental pollution is reduced;
- The VAZ 2107 with an injector responds to the gas pedal much better;
- you can quickly find faults in the power system even by yourself by connecting your laptop to a “smart” injector (if the program is installed);
- For novice drivers, electronic injection is good because it does not allow the engine to stall, it decides what speed to gain, makes it easier to start without revving up, etc.;
- maintains stable idle speed, during a cold start, no “choke” is needed;
- the engine runs more quietly, as a hydraulic chain tensioner is installed;
- no valve adjustment is required, since hydraulic compensators are installed and the absence of gaps is maintained automatically;
- as a result, the injector is 15-18 horsepower more powerful;
