ok here is the deal - my car came obd2(98 civic dx) - but the motor that was put in is obd0 - 1990 ist gen b16a - but they place who installed the motor keep it obd2, well i just recieved a chipped p28 - thinkin my car was obd1 already with a p72 ecu in there - come to find out it is obs2 with a 1996 integra gsr ecu in there..so i now have an inmbred car...what on earth can i do to just go from obd0 to obd1 and eliminate the obd2 completely?

 

if your car is already obd2. i think you can just get the skunk2 conversion harness or anyother harness that converts obd2 down to obd1 so you can run your obd1 ecu. good luck and confusing *** question but i figured it out
