Device Credits for 2015 Ford Expedition

HP Tuners credits are digital tokens used to license vehicles for tuning with devices like the MPVI3. Each supported vehicle requires a set number of credits to unlock tuning features. EFI Live uses VIN licenses, where each license permanently unlocks one vehicle for tuning via AutoCal or FlashScan. Both systems make it easy to add vehicles and manage custom tunes with secure, hardware-based access.
