    Default Looking for stock tune for CMF2450B OS version 52.19.07.0 (PCM 52401932AI)

    I have a 2019 D2 Ram 3500 high output with the Aisin transmission. The PCM currently has version 52.19.05.00 52401932AH.

    I am looking for a stock tune for OS version 52.19.07.00 52401932AI with the asymmetrical CP4 pump. Based on the statements in TSB 18-059-20, I believe there are actually two stock tunes (one for the symmetrical CP4 and one for the asymmetrical CP4).

    Thanks,

    Alan

    Do you have confidence this is for the asymmetrical CP4? I ask because TSB 18-059-20 has this warning:

    "... avoid choosing the incorrect calibration. Choosing the incorrect calibration will result in an undesirable noise from the High Pressure Fuel Pump, requiring the ECM to be flashed again with the correct calibration."

    You need to check the Dodge Calibration ID to confirm, it's not really defined in the Cummins ID's. Anything starting with an 'S' is for the Symmetrical pump.
    Eg:
    52371931AJ = Asymmetrical
    S6371931SB = Symmetrical
    I no longer monitor the forum, please either post your question or create a support ticket.

    Thanks again @smokinpete379. I took my truck to the dealership yesterday, and they did a PCM update to version 52401932AK. Do you are anyone else have the file for this version?

    If there is a repository for these files, please let me know so that I stop asking stupid questions.

    Thanks,

    Alan
