Default PCM question

I'm having a pcm sent to me from pcmforless tuned for my mods. I'm wondering if it matters what year the pcm is from? Mine is a 97, can I get away with running a computer from a 94 if its been tuned?

Are these pcm's assigned vin#'s like the new cars are? Like if we put a scanner on it, will it show the vin from the vehicle it came from?

Yes the VIN is stored in the pcm. Your 97 is OBDII so if you want to run the 94 pcm then you will need to replace the knock sensor in the block with one from a 94-95.

So the vin is stored... my car is a 97 anniversary car, not that its SUPER rare but, should i have PCM for less send me back my original PCM tuned so that it matches the car?
