The oft checks the vin number in the ecu against the vin number in the storred original file in the oft they must match else oft will not write a rom.
sometimes the dealer forgets to write in the vin number to the new ecu or they get it wrong like zero instread of letter o then oft will think it a different car.
if dealer updates your rom to new calid oft will still write but you wont be able to read in the new calid rom so you get stuck on old calid, its not a big drama as oft tuned roms are based on latest calid compatable with your car anyway eg the 700C tuned roms are actually B01C roms inside.
