    Abstract: A method for calibrating an electrohydraulic pump (18) in a system (10) comprising a machine (12) having a propel system (14) that includes an engine (16) connected to an electrohydraulic pump. A micro-controller (20) having software (22) and an input device (24) is connected to a plurality of sensors (26) mounted about the machine. The software uses a plurality of parameters to convert internal analog drive signals into analog output signals to control the electrohydraulic pump and motion of the machine where the parameters include a forward start current value and a reverse start current value.
