Although I had previously calibrated the capacitive fuel senders by setting the empty and full points, I still needed to fill the tank in 2 gallon increments to create the voltage to fuel level mapping. \u00a0I started with an empty tank and created the first calibration point. \u00a0I thought it was a little odd that the sensor showed 5 volts, but didn’t give it too much thought. \u00a0I added the first 2 gallons, but the sensor still\u00a0showed\u00a05 volts. \u00a0I was pretty convinced something was wrong at this point, but I added a couple more gallons to confirm. \u00a0Sure enough, the sensor still\u00a0showed\u00a05 volts. \u00a0I started to worry that the sender was outputting a bogus value, but I decided to confirm all of the settings first. \u00a0Fortunately, I pretty quickly found out that I hadn’t configured the correct input pins on the EMS. \u00a0I needed to switch from the default (pins 20 and 21) to the ones I wired the senders to (pins 22 and 31) and change the input type to capacitive from resistive. \u00a0With that change, I was getting voltage values that made sense for both tanks (2.9 volts from the left tank which is probably around half full and under a volt for the right tank which had the four gallons I just added). \u00a0Unfortunately, I now need to empty the right tank again to redo the calibration. \u00a0I could try to drain the four gallons out, but it’s probably easier to just fly again and run that tank dry.<\/p>\n","protected":false},"excerpt":{"rendered":"
