    Re: MM3 Tuner Troubleshooting

    I got a question on programming.

    I understand that the J1939 Connector needs to be installed to initially program the ECM.

    Once I program the ECM, can I remove everything and put the dummy plug on again?

    I only ordered the 30HP and don't need to monitor or SOTF.

    I will set that all up in my other truck.

    Just trying to cover my bases before I start all this.

    I bought one tuner hoping to do both trucks.

    Thanks

    Yes you can remove the tuner once programmed if that is your wish.

    I figured, once written I would be ok, wasn't sure if it was a signal thing or not to the box that would of tripped something.
