Abstract
A fuel control system for regulating fuel to cylinders of an internal combustion engine during an engine start and crank-to-run transition includes a first module that determines a plurality of step-ahead cylinder air masses (GPOs) for a cylinder based on a plurality of GPO prediction models. A second module regulates fueling to a cylinder of the engine based on the plurality of step-ahead GPOs until a combustion event of the cylinder. Each of the plurality of GPO prediction models is calibrated based on data from a plurality of test starts that are based on a pre-defined test schedule.
