Will the first step of Audi s3 brush hurt the car?

The first step of Audi s3 brush of Pacific Auto Network won't hurt the car. Brushing the first-order program has little effect on the promotion of vehicles, but it will not cause too much harm to vehicles. The biggest disadvantage of brushing the first-order ecu may be that it will more easily lead to carbon deposition in the throttle of the vehicle.

Expanding the ECU of all car brushes has an impact on cars;

1. After the ecu is brushed, the quality requirements for gasoline will become higher. If inferior gasoline is used, it will damage the vehicle.

2. The requirement for temperature is higher. After ecu brushing, the engine overclocked. Without an excellent cooling system, the life of the engine will be affected.

3, 4S stores can refuse insurance. 4S stores can refuse to provide warranty for vehicles equipped with ECU.

2.ECU controls the intake, fuel injection and ignition time of the engine, thus determining the working efficiency, power and torque of the engine.

3. Information such as' corresponding' air intake, fuel injection and ignition time when the engine works under various working conditions such as speed, gear, load and temperature are recorded in ECU in the form of database, which is called "M.A.P".

4. The essence of brushing ECU is to modify this "M.A.P."-database. Changing the data of controlling the engine will affect the operation of the engine and achieve the required effect within the acceptable range of the engine.
