D0919 "Manual Hold Gear, 2nd, 2->3 Shift Speeds

D0913 "Manual Hold Gear, 1st, 1->2 Shift Speeds

It would appear those are the designations of the hold speeds, and (D0928, D0933) are the downshift speed entrees. I would venture a guess that this is not just for EFILive, but part of the tuning itself addresses from the code inside the PCM.

I may be wrong though.
