To reduce lead times for tuners sending ECM's off site to be unlocked, EFILive has added an option to unlock selected controllers by trying every possible key in a defined range for selected controller types.
The controller is erased and unlocked once the key is found and is left in dead-poll mode, the key is not revealed. The final step in the process requires a cal-flash of a compatible operating system to restore ECM functionality (or a full flash if you intend on changing operating systems).
Keys are tried in a random order in the range specified. If a user needs to pause or end the process, select the [Quit] button, which also saves the previously attempted keys. To resume the process, ensure the [Restart] option is checked prior to selecting [Cal Flash] so only unattempted keys within the range are tried.
This option is only available for the following controllers: E38, E40, E67, LS1B, E54 (LB7) and E60 (LLY) and is accessible in the February 2018 Beta software (or later) by navigating to the [F3: Tune] -> [F6: Cal Flash] menu in V8 Scan and Tool Software.
Users can also use the Edit-> Properties -> Tuning Tool -> Read/Flash options to create default Seed/Key Security settings, and password masking.
