I have a 97 civic with a b8cr swap and the scaner wont talk to the ecu,I have check the wiring and every thing is good.I pluged my old ecu in and it works fine.I have a p73 ecu for the b18 motor I was woundering if the wiring is different for the p73or if the ecu is just bad.Any help would be great.
