Hello,
I have audi a4 b7 1.8T 163 hp BHB engine code, i need change injection with audi tt 225hp . i need help because my fuel regulator is 4bar ,and audi tt has 3 bar, my krkte map has adress 0001FA18 but i don"t no factor is 0,000111 or 0,000167?  From factor 0,000111 krkte has value 0.0690, audi tt from factor 0,000111 krkte has value 0.08356 , but if i set this value from my ecu , my car doesn't good start engine, and the smell of gasoline,  if from test i set : 0.0453 , car start engine normal, and no odor of gasoline.

Please tell me how to calculate krkte from 4bar regulator or must i change regulator?

Do I have to look for the value of studying the behavior of the probe krkte at idle?

if I can copy TVUB values of audi tt or calculate?

what else do I need to modify the map to the correct calibration?

Thanks for help,
Best Regards
