Balancing out the elements on the gauge screen, here's the new concept for the Instant (main gauge) display:
Code:
MPG I:24 C:26.2>
MPH35.2 MS20.33<
MPG "I/C" will be fixed on the display (and will be able to toggle between metric units in Preferences). Both MPH and MS2 (M/Sē as I'm hoping to implement, probably as "MPS" instead, so the "2" doesn't get confused) will be selectable to choose a different data point to display in its place - the fun part was finding a way to fit 3-character descriptors on the display so they can be selected without display limitations (all parameters will have 3-character designations, like MPG, MPH, Gal, Mil, Hrs, etc). And each screen's config will be saved in EEPROM as well.
Now to figure out how to make digit display more flexible.
