A license is not required to read an ECM, most likely his ECM is locked by his tuner.
Yep, EFILive doesnt charge for anything except the first flash of an unlicensed (to your FlashScan/AutoCal) PCM/ECM/TCM. No COS charges, changing the VIN (dont need a license to do this), OS upgrade, segment swap, etc.
If you got a security error, it was probably flashed with an HPT COS or the tuner changed the seed/key. Try with V7.5, it might give you more error information.
So if it was hot there's no way for me to save his current tune?
I meant hpt not hot damn spell correction. Gonna use 7.5 tonight to see what's up with it
