so i swap out my ulev motor for a non ulev. i went to put the non ulev ecu on and the car wont start. my question is do i need to reflash the computer for it to read the key?

Just swap over your exhaust manifold/cover from your old motor to your new motor. Also your O2 sensor. Your harness is different than a regular F23A1 harness. EGR Valve is the same. And use the ULEV ECU. Even if you get the A1 ECU to work after getting it programmed for your key, your still going to have problems with the O2 sensor engine harness because its wideband and the F23A1 ECU and O2 harness is not.
kk. i will swap out the harness and see if cel will go away
When, if you haven't already, swap the wire harness, let me know your results. I may want to buy an engine that is already built instead of building mine up and its an A1 and not an A4. Thanks.
