Audi 90 with aan engine problem, cutting fuel

[Ryss]

I think the boost is limited in first gear. It may be you ecu is getting confused as it does not know which gear it is in and road speed is to high for 1 st gear, etc. So going into a massive limp mode.

What process did you go thru to use the standard ECU in the new car?

Do use fit the VSS wire from the ECU to the car?

that's what I thought, and my ECU has a constant power supply on pin 18, and I have power on pin 27 and 37 of the ignition. When I check my error codes, I do not turn off the car, I even tried to ride in the combine diagnostics and no errors

I just wanted to ask in the forum but did not know how to explain it. ECU from a car that had an automatic transmission. I brought the power of the pin 18, 27, 37, I also brought power to the lambda sensor and additional power to the black wire with a blue stripe that goes to the vehicle speed sensor and MFS

I did not bring any wire in the instrument panel. it's not connected, could that mean the same

For Ryss

Being in my ECU automatics, do I have anything else to connect
