Abstract
A method for correcting injection behavior of a fuel injector includes calculating a nominal value of a fuel injector family characteristic for an average fuel injector from a family of fuel injectors as a multi-variable function of engine operating conditions, calculating a corrected value of the fuel injector family characteristic as a function of the nominal value, and employing the corrected value when actuating the fuel injector to inject fuel.
