So I'm trying to assess the use of a few scalars for transmission controls over and above what is documented in my available resources.
Only about 20 percent of the list here from my Mark VIII calibration using Tweecer are defined, the rest is a mystery to me.
There are more than 80 scalars, i've grouped a few.
Need a really good tuner's dictionary.
