I put a 92 b16a obd1 5spd in a 92 vx civic hatch. I have a p28 chipped ecu, the only code i am getting is code#3. MAP sensor. I looked at the throttle body and the stupid thing has no MAP sensor and there isn't a spot for one. Is there anyway of getting around it or should i buy a 94-95 GSR throttle body and get a MAP sensor for it (if it will bolt on) or a typr-r one?
