    2025 RAM Cummins 6.7L - OTA Updates To ECU?

    If true, big brother is 100% in your truck.

    What do you think?

    I am curious if it could be disabled?

    This ought to be interesting the next few years.

    2021 Ram 3500 DRW, H.O., bypass oil filtration, bypass coolant filtration, S&B CAI, 4:10’s
    2wd low loc kit.
    Reacquired 2001 3500, 5.9 nv4500, dually cab and chassis, 5” straight pipe, edge juice w/attitude. Otherwise all stock…..for now.

    I think this will be a big challenge for after market tuning unless the OTA updates can be blocked.

    A lot of us will be buying "older" trucks.

    Just trying to work on my 22 was enough to make me say thats it, I'm done after this one.

    Back to a 4G.

    If you unplugged the associated cell phone linky module and got a "150 miles to limp mode" message, that would seem a bit excessive.

    Let’s hope they don’t pull a stunt like that.

    That is my fear with all the talk of them wanting car-to-car communications.

    Your vehicle will essentially be required to check-in.

    I don’t see how this would not directly violate our privacy rights in this country.

    Like I said, I will not have to deal with it, barring a major catastrophe with my current rides.
