Abstract
A method of load and speed modifying on fuel lean-out for an internal combustion engine includes the steps of sensing a speed of the engine, determining an engine speed modifier as a function of current sensed engine speed, sensing a manifold absolute pressure (MAP) of an intake manifold of the engine, determining an engine load modifier as a function of current sensed MAP, adding the determined engine speed modifier and engine load modifier together to yield a speed/load modifier, and applying the speed/load modifier value to a fuel pulsewidth value of fuel injectors for the engine and reducing the amount of fuel injected into the engine by the fuel injectors.
