Electronic reprogramming is nothing more than changing a car's software, regulating the electronic injection when injecting fuel and at the engine's ignition points, resulting in more power and torque gain, optimizing what comes with the vehicle, this is a genuine and safe change.

What is done?

The engine's electronic module contains software that controls the calibration of all functions, such as fuel injection and ignition advance - according to conditions such as engine speed, accelerator load, ambient temperature, air humidity and even altitude. .

For example, in summary: from this programming, the car knows that being at “x” rpm and with pedal load “y”, it must have the ignition advance “a” and fuel injection “b”, still conditioned to conditions of temperature, humidity, altitude ranges. So, changes in rpm (x) or pedal load (y) change the ignition timing (a) and the volume of fuel injected, as well as climate variations.

The mention of the "chip" for the procedure comes from the 90's, when there was, in fact, a chip that was replaced (or removed for reprogramming). Currently, it is through the OBD (on-board diagnostic) port that access is made to the electronic control module and the alteration of the original factory parameters - basically fuel injection, ignition advance and, when it exists, the turbine pressure. .

The power gain is more significant in turbocharged cars.
