Tuning engine VAZ-2114 - forcing and flashing the computer

It's no secret that domestic cars, including the 14th Lada, are equipped with not very powerful engines. In this regard, motorists are trying in every possible way to increase the power of their iron friend. In order to fully reveal the capabilities of the gasoline engine, it is necessary to increase the volume of the cylinders, that is, to arm the engine. But you can add "horses" in other ways. How to make tuning engine VAZ-2114, read further in our article.

Increase the working volume of the cylinders

This is the most proven and reliable way to improve the characteristics of the dynamics of acceleration of any car. The essence of the work on forcing the motor is very simple - you just need to properly dig out the piston, modify the intake manifold and change the crankshaft. However, unfortunately, it is impossible to do this without a special machine tool, tools, and even more skills. The piston is being pumped on high-tech equipment on the basis of accurate calculations and with observance of dimensions. If the part is at least a few millimeters greater, the effectiveness of such a forcing can not be expected. Similar machines are available only in professional workshops, that's why you can not make tuning of the VAZ-2114 engine in this way.

On a specialized SRT the masters will quickly pick up the most suitable crankshaft (high or lightweight), replace it and properly blow out the pistons of the engine. By time, the process of forcing the motor takes about one day. From a financial point of view, you have to spend a minimum of $ 500 to "bring the engine to mind." Due to the reduced size of the pistons and the modified intake manifold, the engine's power will increase by almost 1.5 times. That is, instead of the old 90 horsepower, we get immediately 135. But the fuel consumption will not be economical - on average, it will increase by 2-3 liters.

Alternative ways to modify the motor

Some drivers repair (tuning) the VAZ-2114 engine independently. Thus all pistons and a cranked shaft remain untouched. How can you increase the power of the motor without boring the cylinders? The simplest way is to replace the regular air filter. As a result, engine power increases by about 5-8 percent. The fuel consumption thus does not increase almost. Together with the filter, motorists recommend changing the regular wires of the candles to high-voltage ones.

In order to increase the maximum number of revolutions of the crankshaft (and accordingly, the power), the cylinders remove the sherkovatosti. Together with them, the inlet channels are polished.

Another way to refine the VAZ engine can be the steel upgrade of the ignition distribution system. In this case, the engine is equipped with lightweight valves and new pushers.

Turbocharger

It is also a very effective way to improve the performance of the motor. As practice shows, after installation of the turbocharger the car becomes more powerful at least by 25-30 percent (that is, almost as when boring cylinders). However, along with this, it should be borne in mind that such tuning of the VAZ-2114 engine entails an additional load on the transmission. Remember that the engine torque should not be greater than the passing torque of the gearbox.

Alternative option - chip tuning

As in the case of forcing, this way to increase engine power can not be done without special equipment. However, it does not use machine tools, but computer software. In fact, the main object of the alteration is the electronic control unit, which, as a result of the work, is being "brainwashed".

In the technical language, the chip tuning of the VAZ-2114 engine is the reprogramming of the computerized ICE control system. It should be noted that there are a lot of "flashing" options. For example, one program adjusts the unit for moderate fuel consumption (to the detriment of overclocking dynamics), and the second, on the contrary, increases the power plant's power (with the car spending 5-10 percent more gasoline than before). Another interesting version of the firmware is the replacement of the ignition timing at the VAZ. Auto tuning of the 2114th "Lada" in this case allows you to switch to a painless absorption of gasoline with a low octane number.

But still, most motorists retune the computer to a higher power. As a result, the car becomes dynamic on the acceleration, fast and fast.

Cons of a flashing

But do not forget about the drawbacks of this chip-tuning. This is an increased toxicity of exhaust gas and an increase of 5-10 percent of fuel consumption. Unfortunately, modern technologies do not allow you to reconfigure the machine at the same time for low consumption and high overclocking dynamics. We have to sacrifice something with one thing - these are the laws of physics.
