2018+ Cummins Fish Tuning Unlock for EFILive

The 2018 CME Bypass Cable, also known as the Security Gateway Module bypass cable is used to bypass the anti-tuning security found in the 2018 Cummins PCM. You will need this cable if you are using EFILive to tune your 2018 Cummins. The bypass cable will replace the two can wires in the factory OBD-II connector (the factory ones will need to be de-pinned) and the bypass cable will be plugged into a large white connector just above the OBD-II in any of the available slots. This can remain permanently in the truck and does not need to be removed after flashing. The OBD-II will retain all normal functionality. The bypass just disallows the Security Gateway Module to filter out the flashing stuff we need to send to the ECM.
