So I have a 1990 b18a1 with auto trans I was wondering what is everything I would need to convert it to OBD 1, also if I use a OBD 1 style fuel rail and distributor do I need an adapter? Also Running a OBD 1 harness for OBD 0-1 conversion on my 97 integra shell.
Any help is really appreciated thank you!
also this is my first time so sorry if I asked anything stupid

 

I’m pretty sure all you would need is a compatible ecu. I’ve never ran anything auto but I always thought the earlier ecu’s run what you’d call a tcm inside. So basically just run an auto b18 ecu if you have a harness
