Flashing license is VIN locked and each vehicle needs separate license. If you choose to sell a car with MG Flasher, the new buyer will have access to all purchases linked with that vehicle’s VIN. In case you choose to take your MG Flasher software with you to another car, we can do a one-time license transfer too. The process will involve deactivating the original car using our app before activating the new car and providing us with both vehicle VINs. The car you will choose to transfer to must be supported. Transfers can only be performed once and do not apply for custom tunes. Not all OTS map licenses can be transferred, it depends on software compatibility.
