I have the current file that i want to fix with oem one because its not okey for the FAP. FAP seems to be turned off wrong and the car is smoking very very high when cold with big white smoke. I fount the problem. They have sold me bin file ,not FLS. So i will write them.

In my settings, I managed to force the throttle not to close, and there was almost no hot smoke. Further, the decrease in the amount of fuel and smoke did not become at all (reached 3 mg readings at idle). And yet there is smoke when starting and warming up. It seemed to me that I was able to turn off the catalyst diagnostics, and therefore I did not increase the air requirement in the "Basic map of the air flow setpoint according to engine speed and the torque for the temperature area ... in diagnostic catalyst mode". As a result, the smoke is cold.
Tuning the motor is a gamble and very addictive. Now I want to know what is EHR mode, FCLO mode, what T3 stands for in "Mass fuel setpoint calculation based on T3 specification provided by PSA."
