I have a 02 accord 4dr with an auto trans. The motor a f23a1 has a blown head. I wish to replace it with a DOHC swap, h22 or f20b, but I can't find what auto OBD2 ecu that I need.. Also what wiring needs to be changed or repined? I am not new to swaps, I did a GSR ek coupe with Miss Jackson on her. But now I am a family man had to get a larger ride. Please help any info on this swap with be helpful.
