How does it work as far as flashing a code? Say I came across a TBE relativly cheap, but didnt have an AP. Is it possiblt to have someone flash me a map, and then disconnect the AP while still keeping the map on the ecu until I could get a protune?
When an AP is married to a car the VIN number is copied over, and if the VIN does not match from AP to car... it is a no go situation. That is how they get away with the one car at a time.
