    Locking requires a full flash (or at least a re-write of the part of the flash chip that contains the seed/key). The Bosch LBZ ECM does not allow that part of the flash to be rewritten. So right now it is not something that can be done.
    We have an idea of how to do it but it is complicated and potentially dangerous to the ECM (i.e. the same potential to fry the ECM as when full-flashing an LS1 controller).
