This option does require that you send us your original ECM, and we will ship you back a different, unlocked ECM that’s programmed to your specific vehicle. EFILive’s FlashScan V2 interfaces with the car’s ECU and is both a scanning tool and a tuning tool. A used ECU would have to be programmed to your vehicle, depending on make and model it can be as simple as using a diagnostic tool to program it or a lot of times it can involve swapping the contents of the internal memory from the old ECU to the new one which isnt a job for the average garage. The dealer SPS wont flash any Global A ECM with another VIN, so you will most likely have to find someone to clear the VIN or purchase a new ECM.
