I have a 96 Civic EX. I'm gettin ready to go from the OBD2 ECU to a P28 OBD1 ECU, in preps for a turbo/hondata setup....I would like to know which sensors I will not use when going to the OBD1 setup. Thanx...

you cant not use sensors...you must use a complete ODBI ecu

True, but there are sensors in and OBD2 system that aren't used in an OBD1 system, such as the secondary oxygen sensor, etc... I want to know which ones in my OBD2 system won't be utilized by the OBD1 computer.
