A method of modifying a general formula that is used by an engine control system (10) to calculate duration of fuel injector actuation. Coefficients (P1 coeff., P2 coeff., ICP coeff.) of the formula are modified to calibrate individual fuel injectors (16) in an engine. The amount of calibration needed is determined by data that is marked on each fuel injector in electronically readable format after the fuel injector has been operated and its operating characteristic ascertained. The control system reads the marked data and then makes the proper coefficient adjustment.
