A calibration method comprises: determining a steady-state (SS) delay period from a first mapping of SS delay period indexed by air per cylinder (APC); determining a predicted delay period based on first and second dynamic compensation variables; outputting a theoretical delay period based on a calibration APC; determining the theoretical delay period from a second mapping of theoretical delay period indexed by APC; generating the calibration APC; populating the first mapping based on the theoretical delay and the calibration APC; determining the first and second dynamic compensation variables based on comparisons of the theoretical delay and the SS delay period; and selectively adjusting an amount of fuel provided to the cylinder based on the predicted delay period.
