1. A suspension controller for calibrating a vehicle air suspension, the suspension controller comprising: a suspension manager configured to (i) control an air suspension of a vehicle to extend to a top of travel and (ii) control the air suspension to retract to a bottom of travel; a sensor interface to (i) read a top of travel value from a first motion sensor coupled to a suspension member of the vehicle in response to control of the air suspension to extend to the top of travel, wherein the suspension member pivots relative to a chassis of the vehicle, and (ii) read a bottom of travel value from the first motion sensor in response to control of the air suspension to retract to the bottom of travel; and a calibration manager to (i) determine a differential travel value as a function of the top of travel value and the bottom of travel value, and (ii) scale relative angular position data from the first motion sensor based on the differential travel value.
