Here is a datapoint for the group, on the differences in the capacitive sender response between fuels. I have calibrated my left tank on 100LL and the voltage ranges from 0.835 to 1.165 volts (empty to full), and when calibrated on 91 octane premium auto gas the voltage ranges from 0.801 to 1.502 (empty to full).
The capacitive sender response is significantly different, you must change the calibration sets when changing fuels if you want to trust your fuel levels.
With Dynon it is possible to have pre-loaded sets of calibration files and switch from one to the other within seconds depending on the fuel you are putting into the tanks, there is a thread discussing this on the Dynon forums. Of course, this also means you would ideally want to have your tank empty or very close to it when switching from one fuel to another.
