I've just noticed that there were already existing decoder files for "Bachmann Sound Value" under this family name in the "Throttle-Up (SoundTraxx)" section.
Unfortunately these files have the same flaw as already mentioned a few weeks ago in this group regarding the function mapping of Tsunami. I have fixed all the Tsunami, but didn't notice this one.
I'm going to fix it and add all missing diesel models including SD70ACe (and GEVO).
