Abstract
An engine control system is described. A cylinder control module selectively activates and deactivates intake and exhaust valves of a cylinder of an engine. A fuel control module disables fueling of the cylinder when the intake and exhaust valves of the cylinder are deactivated and, when the intake and exhaust valves of the cylinder are activated after being deactivated for at least one combustion cycle of the cylinder, adjusts fueling of the cylinder based on a predetermined reactivation fueling adjustment set for the cylinder.
