Bgill has the formula.. fill the tanks, fly the plane on a regular flight, then write down what the totalizer said you burned, and what the fuel pump said you pumped in. Use the formula Byron posted and you can accurately adjust your K factor. I noticed on my plane that using the electric boost pump shows the fuel flow higher than actually using, so maybe for purposes of this calibration, minimize the time you use the fuel pump or don’t use it while doing this calibration, unless your setup is uneffected by the electric pump. The longer the flight, the better sample and accuracy, but you can even do several small flights without refueling, but there may be some inaccuracies compared to one long flight.
