Unless you drive a GM w/HP Tuners or EFI Live… then everything passes
Not that I WOULD do this, but VIN identification isn’t part of the OBD2 standard…soooo if someone is shady, they can plug in ANY OBD2 car in place of theirs and as long as it will pass…
But, that would risk someones inspection license, and could probably get them prosecuted.
I know someone will argue this with me, but I have had plenty of experience with OBD2 ECU’s to know that VIN number identification is only on certain vehicles and it’s not in the same place on every one even if it does have it.
You can’t require something that doesn’t exist in all situations
