Thanks! I am rather proud of the time/distance-to-empty functions, myself. They do not randomly jump around.
The tank size is a parameter that can be edited in the settings, just like metric mode, the inactivity timeout, and that humongous microseconds per fuel quantity number. I think it was present in the original 0.86 code, but it was never really used. The tank size parameter is affected by metric mode - if metric mode is set, the tank size is displayed and entered/edited as liters. Otherwise, it's in US gallons.
I changed the display coding a bit, to enable a somewhat higher resolution graphic display. I simply despised those blocky bar graph characters. Now it's easier to see the characteristic MPG curve as a function of vehicle speed. The above picture was from my commute into work today. I managed to squeeze in 17 different speed segments into that display. The fuel used / speed, time / speed, and distance / speed graphs look similar, but they do not have that nice curve that I wanted to show. The fuel economy / time screen also uses the above graph coding.
Tonight or tomorrow, I am going to add EEPROM parameters to select the speed range, enable saving this data to EEPROM, reset it by itself (currently, it resets when the tank trip is reset), and examine it from the shown screen.
The differential fuel economy / time graph (like the one below, from the ScanGauge E) does not appear to work yet. I probably miscoded something simple.
