Ok long story short my brother has a 95 integra gsr (obd1) and I have a 97 integra gsr (obd2). and now he has put a turbo on his car and has it tunned by neptune, so he is giving me his s100. the question is can i still use the s100 in a obd2. when it was from a obd1 ecu. does it matter what obd it is?
i have search and cant find the answer that im looking for.
Thanks Nick.

 

you cant use it on the obd2 ecu but if you get a obd2 to obd1 conversion harness and a obd1 chipped ecu you can use it

 

You would need a conversion harness like he said. This is what im going to have to do since i have a 01

 

I have a 98 obdII gsr. i'm using a p28(obdI ecu socketed with s100) w/ obdII - obdI conversion.

Why bump? You have your answer already.

 

Those guys were right...you aren't going to get another answer.
