Black box "swap meets" could be the wave of the future. Just show up, pay a fee, and your black box is swapped with one out of the next car in line, totally at random. The swap would never be discovered until Uncle Snooper actually tried to track you...
I don’t understand your post.
Why would I want the vehicle computer out of some other random car?
It’s immediately going to spit fault codes because the VIN is incorrect.
