This means once found they can enter in the unlock key to their desired tuning tool and read the file out (tuners get pretty mad about this).
Over the years we've considered coming up with far more elaborate ECM locking systems than what GM have but in the end 99% of the time the only person that will inconvenience is the innocent tuner or the car owner so it wasn't worth it.
The hope is that with all our customers now being able to unlock ECM's it should reduce down time when locked vehicles come in for a tune, plus the way it works the tune ECM will be removed when the ECM is unlocked so it works along side the industry rather than exposing all the secrets tuners might have in their tunes.
