Abstract
Various methods and systems are provided for indexing an injector map and subsequently controlling fuel injection to an engine. In one embodiment, a method for the engine includes injecting fuel via activating an injector for a determined activation time, the activation time determined based on a commanded fuel value and a function of a modified pressure difference across an orifice of a nozzle of the injector, where the modified pressure difference is based on a difference between a rail pressure and peak cylinder pressure, the peak cylinder pressure scaled by a function of engine speed and injection timing and the pressure difference offset by a correction factor.
