Every petrol engine has a specific ignition advance. With chip tuning, the restrict of the pre-ignition is elevated a little bit additional.

As an example: On a selected engine with factory software, the ignition advance varies between 30 and forty levels BDC at 4700 rpm. When growing speed to 5000 rpm. the engine will go to zero levels pre-ignition.

The tuner will set the restrict at 5000 rpm. enhance it to, performance solutions for cars instance, 5200 rpm. and only swap to 0 degrees pre-ignition from this velocity. This results in a power achieve, as a result of the combustion pressure is higher at this speed.

Turbo pressure:

By increasing the utmost turbo strain, a larger amount of air enters the cylinders. By adjusting the gasoline amount (injection time) to this, sturdy power gains are achieved. Turbo pressure is controlled by the Waste-gate. This valve opens at a sure pressure (eg 0,eight bar). The tuner will improve this strain to eg 1 bar. The valve will solely open when a filling stress of 1 bar has been reached.

Injection Time:

By adjusting the injection time, a larger quantity of fuel might be provided to the incoming air. When the turbo strain is increased (extra air flowing in) and more gas is injected, there is quite a lot of energy achieve.

Not only the characteristics of the ignition, the turbo pressure and the injection time should be adjusted, but in addition the traits of all sensors and actuators of the engine.

For instance the knock sensor: If the characteristics of this should not modified, this knock sensor will react to the injection time that doesn’t correspond to the factory values. This produces an error code within the ECU (and it could possibly find yourself in an emergency program). Each map discipline of each sensor should subsequently be programmed to the adjustments that have been made.
