Abstract
An internal combustion engine control system processes data to develop desired fueling data representing a desired amount of fuel that is to be injected into the engine for combustion. The desired fueling data is modified by a multiplier during a cranking, starting, and initial running phase of the engine, and after the engine has started and begins running, modifies the multiplier by a multiplier adder. Use of the multiplier added is discontinued once the engine fuel injectors have sufficiently warmed up. The multiplier adder is a function of an average of desired fueling data taken over a time interval that includes engine cranking, starting, and initial engine running.
