    Default 2008 Ram 2500 with a download not accepted code $0340

    2008 CMC and Get's all the way to the end of download and says "Script exited with code $0340: Download not accepted ($40)."

    Any Ideas ? Thanks in advance!

    Sounds like the ECM might still have the anti-tuning protection enabled. Depending on what version of software you are using depends how it can be disabled, the method below works for all versions.
    There is two .ctz files you can use to disable it (if that is the problem).

    Under 'C:\Users\YourName\Documents\EFILive\V8\Tune\CMC'
    CM2100A_BootRSA_Patch_Auto.ctz
    CM2100A_BootRSA_Patch_Manual.ctz

    Flash the matching one in, then after doing that you should be able to flash in the modified file.
    I no longer monitor the forum, please either post your question or create a support ticket.
