My Sonex has a Dynon EFIS, and capacitance fuel probes - not the the way I would have done it (I see a lot of people trying to turn Sonex into RV-7s and IFR at that), but it was all very neatly installed on this 98% done/98% to go project I bought. I'm puzzling out how to accurately calibrate the probes/EFIS, without spilling too much gas all over the place.
I'm thinking that every time I go to the hangar, I take a carefully measured (at the pump) gallon of 91 octane, add the fuel, fire up the Dynon, and then tell it how much that REALLY is. Rinse, Repeat. Once I get the tank full, then I'll drain at least 5 gallons for the fuel flow test, and use up the rest in setting the carb, doing a "climb attitude engine run test" or whatever the EAA test card calls it, etc. The gas I drained then goes into the airport car - I don't want to leave much, if any gas in the airplane, as it needs to go back to a different airport and the "oxygenated" gas, which is the only kind you can get in California, has dreadful storage properties.
Any feedback? Any better ideas?
