I'm having difficulty calibrating my restance fuel tank level. Wired tank sender to pin 20 (orange brown wire) for left tank (capacity 24 gal), filled in 2 gal increments, got ocassional messages that the sender value did not change, punched full as directed. I'm now installing a dedicated ground wire but would like to make manual empty and manual full entrys when I raise the float to the top of the tank. How are manual entrys accomplished? Many thanks Murray Randall

I'm assuming Skyview. Export the files from the SV. Open the file with EMS in the name. Search for a line starting with user_cal={. One of the user calibrations will be your fuel tank. There may be several user calibration sections depending on how many fuel tanks, flaps, etc. The format will be obvious. Edit to your hearts delight. ;)

Save the file and load it back into SV. You only have to load the one file, not all that were exported.

I also had some trouble with my fuel tank calibration in that the float stuck once in a while. I shook the plane after each increment and then let the float settle before I pushed the button. My fuel levels are still in question. Depending on pitch the levels can vary quite a bit. If I'm low on fuel, pitching down on descent can make the fuel level look critical. I rely on fuel burn and dips more then the fuel level gauge plus the gauge can't read the first twenty liters so when it reads empty I suspect I have twenty liters left.

One other hint. If you go back to the fuel calibration page in the SV setup, the voltage that SV is reading from the sender at the current fuel level is shown in the upper right of the page.

Murray - The EMS-D10 does not have a manual edit ability, unfortunately. But more fundamentally, that message means that the output from the float isn't meaningfully changing. If you're not getting that message all the way from empty, but only from some point once you've filled at least a few times, it's likely that your sensor has actually topped out and has stopped moving. In that case, the only thing that makes sense to show is that the tank has at least X gallons in it, where X is where the last amount of fuel actually detected. So if you have 20 gallon tanks, but the 16 gallon fill is the last fill that was detected, you'd see 16+ on the gauge when it's full. Just like your car, the gauge would then sit full until the sensor actually starts to move down.
