Heres the info your requesting
Thanks to 505live on TheDieselstop for the info;
I found the codes to get coolant temp for my 7.3L out my Scangauge II xgauge:
Here's the catch, and why I don't think scanguage advertises the code: The signal changes resolution part way through the warm-up and the math can't be triggered to change with it. It's really simple tho, below 127F it reads 2x the temperature, so as the vehicle warms up the reading is double until it reaches 127F. I.e., during w/u the gauge will read up to 254, then when crosses 254 it will switch to actual temp and drop to reading to the "actual" 127F, after which it remains accurate.
I punched this one in this morning, and verified it works on my xgauge.
