Abstract
A system for calibrating an electrohydraulic pump using a micro-controller that has software that may command the engine to a speed value and to uncommand the electrohydraulic pump such that a baseline engine load is defined. The software may also, thereafter, command the electrohydraulic pump to ramp up until the electrohydraulic pump goes into stroke thereby increasing the engine load to an amount over the baseline engine load. When this occurs, the software may define a start current value for that direction of the electrohydraulic pump.
