hey guys, did some research, but cannot get a straight answer... Im purchasing a used LS1 with ls6 intake, cam and injectors and his pcm. The donor car is a 2002 ws6 w/ t56 and my car (the engine its going in) is a 99 z28 w/ t56. Im 99% positive the pcm and pinouts are the same. However im not sure about the PASSKEY working. Will i need to reprogram my key to work with his PCM. Only reason why im taking the pcm is obviously its already been programmed for the upgraded engine. I could plug it in and drive it to the dyno shop and maybe have some fine tuning done and reprogram for my gear ratio... thanks

passkey is programmed to match the key on the car. new ecm, new program.

why not get it programmed out then drive to the dyno?

You need to do a vats relearn, it takes 30 min and no tools are needed.
Then go to the dyno and have you VIN changed to match your car
