    I'm not sure if efi will support it being it can't be done directly from the obdII port. I also don't know what can/will be done with tuning after its been unlocked with BullyDog as far as efi goes..... Bully Dog is gonna just be your best bet for the time being.

    It can be tuned via the OBD-II port once the BD box has done its thing.
    So for a shop situation to offer custom tuning using EFILive the 2013+ ECM would first need to be unlocked via the BD device, then after that one off process you are right to tune via normal means. Of course Cummins have been plugging these security holes since the 2008 ECM first introduced the RSA signatures, it might be in the next gen ECM or a CM2350 update they will see the error of their ways and close the door BD use on the 2013+ too. But for now we have a life line.

    Whoa this would be big of Efi was first to release tuning for 13+ but I'm guessing this isn't something we will see soon?

    Haha. I meant unlocking it can't be done from the obdII port. My bad.

    Would be pretty cool to have the tuning for them.... but a pain in the ass to have to buy the whole BullyDog tuner setup just to be able to unlock the ecm. But you gotta pay to play....

    I don't think you have to buy the tuner just the unlocker device? Right?
