Hello all. Hopefully y'all can help me with this problem. I done a f20b swap in my 90 accord. I have a chipped p28 ecu but my car wont run off of it for some reason. I know I have a good chip. My car runs off the stock f22a computer but of course not to its full potential. Kinda leaning towards a bad computer but I would like to test ecu first before I buy another one.
