Abstract: A method of operating a fuel injector includes determining an actual energizing time correction value for a fuel injector at a first fuel rail pressure, calculating an extrapolated energizing time correction value by performing a mathematical calculation on the actual energizing time correction value, and controlling the operation of the fuel injector based on the actual energizing time correction value and the extrapolated energizing time correction value.
