Can someone explain the collaboration to me?
Please provide the text you would like me to translate from German to English. I will then provide the translation without any explanations.

If the load jump is reduced by means of a resistor...
(TDI AFN with boost pressure sensor) increases, the control unit detects this.
Yes, that's because the air mass is rising.
Since a resistor is connected to the LDS, it goes...
The control unit is calibrated to a false reading of 1 bar.
(in reality, it would be something like 1.1 bar)

Does the engine control unit increase the fuel injection volume based on...?
of the higher air mass?
Or is the boost pressure processed as the primary signal?
Will the start of injection also be advanced accordingly?

Hi,

As long as all components of the EDC system are functioning correctly, the fuel injection quantity will generally not be increased.

Since the injection amount is not increased, the start of the injection remains the same.

More details about the background information can be found in the specialized articles on LLK tuning and LMM.
