Are PCMs vehicle and year specific?

For example if I want to replace my 2002 Corvette Z06 PCM do I have to use a PCM from another 2002 Z06 or can I reprogram a PCM from another Corvette or F body to work?

I'm going to be moving and I want to be able to send a PCM to my tuner for reprogramming while I keep another in the car to allow me to drive it. My tuner uses EFI Live for programming if that is pertinent.

Thanks,

Mike

a 99-02 PCM is essentially the same hardware... F-Body, Y-Body, Truck ... so long as it's a V8 (may be some differences here or there though... I blieve it's 4.8,5.3 and 6.0 L trucks)

you can reflash to run any OS supported in those years (2003 may be hte same too but I'm not 100% sure)

Jes at waitforme will know for sure. He has stacks of the things. Im pretty sure they are all the same too.

Would there be any advantage of flashing an 02 F body PCM to a later date? As in better fuel calculations or maybe newer code could take more advantage of the faster clock in the 02+ PCM????

The factory pcms are well within the range for Calculations to be handled fine. 100 Cpu load is well above 8500 rpm on a newer pcm.. Some are over 9500..
