Trying to switch VINs and getting Invalid VIN OS Pair?

[MaketheCoin]

I never ran into this but Im trying to take a 02 F body Computer and switch it to a 00. When I type in the new VIN that is the message again.

[Bill@HPTuners]

It must have a valid vin for the operating system your using. You can check what operating systems were available directly from GM for a specific vin by checking GM's own website http://tis2web.service.gm.com/tis2web

So is it saying that part number computer wont work with that car or something? I dont understand?

[Bill@HPTuners]

If it wasnt an operating system GM offered for that Vin we will not support the combination. We go by GM's standards when it comes to operating systems.

[MaketheCoin]

But how come I was able to tune the car that the computer came out of and now I cant on this one?

[Bill@HPTuners]

because your trying to change it to a vin that was never available for that operating system in the pcm. Have someone with a tech2 flash it to a valid stock file for that vin and read that file out & you'll be fine.
