Well the summer is here and the motor has arrived now. Ive been doing some research on my motor. 98 spec ITR stock obd2. My question that i haven't solved yet is,do i have to convert my hole car over to obd2 or do i only convertor the engine harness(obd2 or obd1) What do must guys run for this motors in the REX's. I plan on building the motor if that helps out. Also other question is if i go obd1 P28 computer? or another obd1 computer and ive also heard people saying that if you get a p28 comp and chipp it don't chip the vtec to low bc its bad in the end. I was thinkin that vtec hits at 5grand or is that too low. Thanks alot for the help guys

Ohhh...Lot's of questions and i have lots of answers but little time.


To keep it short and sweet:

I run a p28 chipped from Phearable.net. It is fine for a stock motor. He can set you up with a basemap for your application. Ideally you'll want to get the motor tuned once you build it. So keep that thought open. My ecu is hondata ready which means all I have to do is buy a S200 and plug it in and go get it tuned.

I used my OBD2 dizzy and injectors and had it wired so I could use it.

I think the JDM P72 ecu is OBD1 and usable also. Some people use it because it doesn't look for a vtec oil pressure switch or a knock sensor (I think). That's just another option though and I don't "think" it has any real advantage over a chipped P28.
