    Depends on the ECM type.
    All HD based ones can be read out, only 2006-2009 Dodge ones can be read out, 2010+ cannot.
    I no longer monitor the forum, please either post your question or create a support ticket.

    You can't read a 2011 via OBD-II, I can't think of how the software would have allowed that selection to happen because that ECM is not even available to manually select as a readable ECM.
    I cannot understand your last question.

    I don't believe so (well, I don't know to be honest never having worked at Cummins), it is only the Dodge ECM's that are like this so I guess they wanted them better protected.
    You can download the stock files from here though, you just need to identify what is in the ECM first.
