The FlashScan V2/AutoCal VIN licensing scheme does not rely on the VIN but on other non-VIN data, unique to each controller. Each VIN license is capable of tuning one supported engine controller (ECM or PCM) and one supported transmission controller (TCM). The ECM/PCM and TCM do not need to be for the same vehicle. There is no requirement to return your FlashScan hardware to EFILive. VIN licenses are delivered via email. Automated license processing occurs within approximately 20 minutes of correct order placement.
