EFILive FlashScan V2 Scan and Tune or AutoCal versions require a VIN license for each VIN (i.e. vehicle) that is tuned. Each V2 Scan and Tune Tool includes two VIN licenses that you may use to tune any supported vehicles. Each AutoCal tool includes one license.
You are not required to nominate which vehicles you will be tuning prior to purchasing EFILive. If you wish to tune more vehicles than your V2 or AutoCal has licenses, you may purchase additional VIN licenses.
