    me and my buddy just finished a 96 LS swap into my 93 SI. Everything is working fine. but i had one question. The SI ecu is a p28 and the LS is a p75. Could i still use the p28 to run the LS engine?????

    Yes, but it won't run very well.

    Why not just get a LS ecu from 92-95?

    how poorly will it perform. Cause im using the p28 right now. and my check engine light comes on, but the car runs fine. Is it looking for a vtec code or something??? I guess i should get a p75. Just have to find one!!!

    Yes...the ecu will look for vtec...that's why its throwing a code.

    If you cant find a P75 or dont want to spend too much money just to get rid of the CEL. Email me, rtzcom@yahoo.com. We can get you a really nice custom program for the P28 that will run your car nicely and we will also disable VTEC so you wont get that annoying code.
