EFILive FlashScan V2 Scan and Tuning versions require a VIN license for each VIN (i.e. vehicle) that is tuned. Each V2 Scan and Tuning Tools includes two VIN licenses that you may use to tune any supported vehicles. You are not required to nominate which vehicles you will be tuning prior to purchasing EFILive. If you wish to tune more than two vehicles, you may purchase additional VIN licenses for $125.00 each.
