A method and system for adaptive feedforward control of a fuel delivery system provides for adapting a normalized pressure input and a normalized flowrate input to a feedforward voltage look-up table. If low fuel flow and high manifold pressure are detected (104), then the normalized pressure input will be adapted based on a target fuel rail pressure and a pressure multiplier PMUL. If high fuel flow is detected (106), then the normalized flowrate input will be adapted based on a target flowrate and a flowrate multiplier FMUL. The present invention provides adaptive feedforward control without the need for the look-up table to be stored in a keep-alive memory (KAM).
