All of our remote tuning devices are locked to the vehicle VIN. The older Directflash units did have a rest function for the original owner but that does not allow the unit to be used on a different vehicle as it remains VIN locked. The only way the Directflash would work on another vehicle is if it was sent in to us and replaced which is very rare. The Directflash is no longer sold by us, it has been replaced by the newer E-Flash.

It is always best to check with us before buying used ESS remote tuning devices. Unless the device was never plugged into the car it is most likely no good to a 3rd party.
