    Disable P0128 code?

    I have a 2008 Magnum R/T, an Intune i3, and the canned 91 octane tune flashed to it.

    I have the 176 degree Duralast 4127 thermostat and have adjusted the fan settings accordingly.

    I find myself constantly getting the P0128 CEL for the engine not warming up quickly enough. Other threads have stated it's possible to disable this check as it's common with lower temp thermostats.

    I can't find a way to disable it with the Intune - is this something that needs to be added to custom tune and then re-flashed?

    Thanks.

    You may have a defective T-stat. When I lived in Rhode Island I would get a few, with the same T-stat, in the winter. Expect it to open at 172* and be fully opened at 175*. The computer sees it as time. I'm guessing the heat threshold is 173*. The time threshold is around ten minutes. Both conditions need to be met or the code says hello.

    Yes, its something that needs to be addressed in a custom tune.
    If you don't currently have someone tuning the car, email the last tune written from the device to me at mlitsch @ powerteq.com and I will set it up.


    Thanks
    Please don't PM me, I don't always have time to go through them!
