het h-t,
i have a 99 civic si,think its obd2b,i have a 01 gsr engine in it,which is also 0bd2b.my question is can i use a p72 obd2b a05 or will it not work becuase the immobilizer,or do i have to use a obd2a ecu a03 and get the conversion harness,inspection is tommarow,thanks.

ps:bought a p72 ecu obd2b,but he sent me a a04 with a fuel pressure sensor which wont work?,can i use this? or return it for a a03 or a05,thanks

No OBD2B Integra ECU will work unless you remove the immobilizer and install a dummy chip (katman at least used to do this for a fee, you can PM him for details)

would a p2t from a 99 civic si work for inspection with it running like a 1.6

Yes, it should work for inspection, just don't rev the motor all the way up. You may have to drive around 20-30 miles for the readiness monitors to set...
