    TCII not changing VIN

    I can't get TCII to change the VIN on a .cal i'm trying to load.
    I've got it on a bench harness,it is reading and loading okay but it will not take a new vin.
    I've changed it in TC,I've changed it in hex editor,i've changed it as a bin and as a cal.
    I've changed it with winflash,i've changed it in HxD-i'm about to have a cow.

    Not sure what is up with it,every time I change and reload it just comes back up on the vehicle info as the same V6 VIN.
    Not even sure where it came from,must have been on the guy's pcm. I think I just labeled the OS number in the file and saved/programmed over.
    Generally I don't care what VIN says,so must have kept the previous VIN but now I can't change it.

    Does the serial info have anything to do with that?
