I am getting a swap with a b20 and a p72 ecu. Im wondering if i can run the p72 with no big issues until i can get the p28 i have now chipped? Any check engines lights or anything that will throw it into limp mode?

 

If i were you, i would run either a PR4 or a P75 ecu from an LS engine.

 

im just wondering if i can run it for a little until my p28 is chipped for a b20?

 

I think that is a negative sir. Plus you can pick up a LS ECU for *<20.

 

LS ECU works fine that is what I am running on mine. OBD-1.
