Abstract
A method of determining start of closed-loop fuel control for an internal combustion engine including the steps of determining a base fuel pulsewidth threshold, ascertaining whether a current accumulated base fuel pulsewidth is greater than or equal to the base fuel pulsewidth threshold, updating the current accumulated base fuel pulsewidth with a value of a previous accumulated base fuel pulsewidth plus the current base fuel pulsewidth if the current accumulated base fuel pulsewidth is not greater than or equal to the base fuel pulsewidth threshold, and beginning a closed loop fuel control of a plurality of fuel transferring components if the current accumulated base fuel pulsewidth is greater than or equal to the base fuel pulsewidth threshold.
