Does anyone help me abouth to get a tuning eprom file for E34 M5 3.8. (motornic 3.3)
I have a eprom burner to burn in a file to a empty eprom.
In my car I have a oem (original) eprom. I wanna know what is a difference between the normal and the tuned eprom.
How I feel the engine not so strong from idle to 5000rpm. Above 5000rpm ewerything is ok. The vakum resonance flap is working. I tested.
I have some eprom file for BMW E30. I can send back.
