    Default LML Duramax quit switching tune levels.

    2013 Silverado 2500 with DPF delete and Motorops 5 position tune. Everything worked correctly after install and a few months later the tunes would not switch (always in level 1 regardless of switch position) Switch is working and can be verified by monitoring T1 on the live data. I have sent data logs to my vendor and they can not solve my problem. Any ideas what is going on? Thanks

    This set-up is not created by or supported by EFI-Live

    Your better off continuing a dialogue with the tuner who supplied the tunes to you

    Tuner of many, many Duramax and Cummins Diesels.

    Tried that and they have no clue. They did send me a single race tune and the truck made a lot more power which tells me that the problem is most likely the tune. Any ideas?
