    Rob thank you !

    I looked at the tune you sent me and the Auto-Lock Controller during flashing is checked/ Would this cause the issue of not being able to have the GM tools reflash the ecu ?.

    E60 (LLY) does not use the Locking patch, it uses bootlocker which only requires the Auto-Lock check box in V8 software followed by a flash.

    Locking the controller using Auto-Lock prevents the tune file from being read and flashed with external software. EFILive software will block reading, but EFILive software will still allow flashing.

    Cindy, Thank you. SO if i understand right if the autolocking is turned on and I try and reflash the ECU with a tech2 to have the dealer try and reflash it will not work as "Auto-Lock prevents the tune file from being read and flashed with external software" but i can still flash using my V2

    Correct. You'll need to flash an unrestricted file (auto lock unchecked) for the dealer to be able to flash it.
