Ok i just bought a obd II gsr motor and the guy gave me a obdI ecu, it should work right without any CEL?

 

You know you need a conversion harness right?

Also it depends on what kind of ECU I think and/or if you're missing any sensors.

 

it depends on which make and model vehicle you have?!

obd1 is 92-95
obd2a is 96-98
obd2b is 99-00

if you have a 92-95 then that swap will work perfectly!

96-98....you'll need the conversion harness for the ecu same for the 99-00

they both are different!!

it won't throw any cel codes unless you have some defective parts on your swap!?!?

If you don't have VTEC pressure switch because it's a JDM GSR or ITR, you might want to check out phearable.net and talk to John Vega. Buying a conversion harness needs to be altered a little.
