Hi All. We just completed an engine/trans swap from my son's wrecked 06 ST to an 07 SES ZX5. The ZX5 is (was) a 2.0L/auto. The ST was of course the 2.3L/ 5spd. We swapped out the ECU and the engine/dash/ECU wiring harnesses. Are there options to either keep the 2.3/manual ecu parameters, but change the VIN? Or modify the ZX5 ECU to be a 2.3L/manual instead of a 2.0L. I know we can run the 2.3/manual ECU, but we run into problems when getting the car emission certified due to the different VIN. Any help is appreciated! Thanks in advance.
