I was installing my chipped p28 ecu into my friends 2000 gs-r with a obd2-obd1 harness and when we start it up the car starts for a second then the rpms just drop and the car stalls.
Has this happened to anyone?
Could it be the harness or the ecu or is it just not meant for a gs-r?
Any help would be greatly apprecaited
TIA
