E67/T42 Mapping and Modding

In case you didn't already have it, here is the mapping for 0x1F1 message. I am guessing TCM is looking at Throttle Progression Request? My notes say there are 3 possible maps (A, B, C)

Which ECM is that? If it's the E67, that's extremely useful, if it's E38 that's still very useful to me.

I am pretty sure it is both

OK-I have been able to turn on 0x1F1 messaging and confirm that the maps are being changed in both the GTO and Trailblazer T42 OS. Still working out all the details, and trying to work out a safety check to make sure that it does not change tables into a mode that is not configured...by default, all the maps are either maximum or zero, and I gotta make sure there is a safe, functional map in place before swapping!

Also, I gotta make sure that the Abuse Mode and Adaptive Shift mode are behaving with the new table switching.
