This question is actually for a friend of mine.

He has a 95gsr motor, using the stock harness with an obd1 ecu. He is using an obd2 b16 distributor. Since the obd2 motor uses a crank angle sensor at the crank and an obd1 motor uses it at the distributor, will there be a problem? He says the car starts but it is misfiring the #2 cylinder. When he checks the MIL or CEL it shows code 9. which is the cylinder position sensor. Well, help if you can and thanks in advance.

 

tell him to use an obd1 dist. did he rewire the dist. plugs to fit the obd2?

 

The distributors are the exact same with the only difference being the dizzy-engine loom connector... I personally like the OBD2 one better just because it looks a lot cleaner using ONE plug... They both contain the CYP, CKP, and TDC sensors, but the thing that OBD2 has in addition is the crankshaft speed fluctuation sensor (CKFS) mounted on the oil pump... I've done this same connector swap many times for OBD1-OBD2 and vise versa without a problem... Good Luck...

 

thanks again... Yea im running an obd1 dist on my obd2 motor without the sensor near the oil pump connected. It works fine. Is there anything else that might be causing the #2 cylinder to be misfiring? Pretty broad question i suppose.
