Upgrade your existing FlashScan V2 Scan Only or FlashScan V2 with Dodge Cummins Tuning to include supported GM vehicles. Two VIN licenses are included. 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. 97/98 LS1 Stream is also included. There is no requirement to return your FlashScan hardware to EFILive. Tuning Options and included VIN licenses are delivered via email during regular New Zealand business hours.
