I've searched everywhere. I'm going to the pros now. Got a 1996 accord with a Jdm h22a in it. . the car and engine are obd2. Been running a obd1 ecu with a harness for years, everything runs beautiful. Due to a need to pass "emissions" in my state, I acquired a p13 1996 prelude ecu, the exact one you need, can't remember the exact ecu code. According to EVERY swap post I read, you need to switch pins a6 and a11 on the stock harness to have the ecu work correctly. So I did. Despite everywhere saying pin a11 was for the injectors. So I swapped the pins, and, instant CEL. Vtec failure, o2 heat failure. I'm stumped. Car idles like crap, wants to die. Anyone? Please?
