Anyone have any advice on what I can do to maybe put a stand a lone ecu in my lotus instead of the forcefed piggyback I have? my car is running super rich and idle surges. check engine light always stays on for like 5 minutes when starting it and goes away. I don't know what the problem is because there is no way I can read it with the piggyback. I am ready to give up on the car and get rid of it. can anyone help me?
