ok i have a 95 integra, i put a B18c type r motor in it, it came with a p73 ecu (obd2) and i have a obd1 harness, who makes a conversion for that? cuz ive only seen a obd2 to obd1 harness (skunk2,boomslang etc) but wouldnt i need a obd1 to obd2 harness?

and if i cant get a harness that goes obd1 to obd2, hondata has a p72(gsr) obd1 ecu, i can have that tuned to the specs of a p73 or better? im not sure about hondata i really want it cuz the s200 system is 300.00 and i know a guy that can tune it.

 

That was exactly the situation i was in with my motor. I couldnt find a harness for obd1>obd2 anywhere, I'm not sure if they exist.

I ended up using the p72 with hondata stage 2 and having it tuned. Everything worked out great that way.

 

the obd1-2 harnesses do exist........I think there was another member on this board who just bought a chipped p28 off of me. He had a obd1-2 harness for his jdm itr swap so he could run the p73 ecu....but now he likes my chipped p28 better. I'd recommend just going with hondata right off the back. Dont even bother looking for that harness and spending more money that you dont need to..YOUR OBD1 already, what more can you ask?! LOL PM me if you really want that harness, I can find the guy for you if you want.
