Alright so I currently have a b18a1 in my ef dx. I've already done dpfi to mpfi. I'm pulling out to swap obd1 b16 into my hatch....I need some advice. Should I run obd0 pr3 and use obd0 dizzy so that I do not have to modify my harness, or should I run p28 and obd1 dizzy? If I do use obd1 ecu is there anything else besides diy that I need to change? What about vtec? How do I wire vtec up? Any write ups? And what about knock sensor, will I be better off just chipping ecu so that it doesn't look for it? can I usew obd0 ecu with obd1 dizzy or obd1 ecu with obd0 dizzy and have no problems?
