Abstract
A method of operating a fuel injected multi-cylinder internal combustion engine includes establishing a flow shift compensation term by comparing a pre-flow shift value with a post-flow shift value. The pre-flow shift value is indicative of a pre-flow shift fueling signal duration linked with an engine test speed, and the post-flow shift value is indicative of a post-flow shift fueling signal duration linked with the engine test speed. The method further includes controlling an engine speed via outputting fueling signals from a digital engine speed governor to a plurality of fuel injectors of the internal combustion engine. The fueling signals have a fueling signal duration based at least in part on an electronically stored fueling signal value and the flow shift compensation term a multi-cylinder internal combustion engine includes a control system configured to control an engine speed via outputting fueling signals having fueling signal durations based at least in part on electronically stored fueling signal values modified according to the flow shift compensation term.
