    Thanks Joe
    Previously I have left these alone thinking that they are a torque reduction during the shift and not active during "steady state gear". I am using DVT to hold a gear on the dyno.
    Which table affects which gear for non shifting accelerations. ie. Is the 2-3 Shift or 3-4 Shift active during a 3rd gear sweep.

    Zeroing these Upshift tables doesn't alleviate the EXT_XMSN_DMA activity. Attached are the cal and a log.

    Could someone please peruse the cal to see what I may be missing.

    I am completely at a loss with this thing.
    I have tried all I can think of including B6614 setting from 0 to max or 866.
    Please see most recent cal file and log. Please assist.
