Abstract: The present disclosure provides a system for adjusting a fuel injector drive signal during a fuel injection event wherein the system comprises an engine having a fuel injector, a fuel control module configured to generate control signals corresponding to a desired fueling profile of a fuel injection event, and a fueling profile interface module that outputs drive profile signals to the fuel injector in response to the control signals to cause the fuel injector to deliver an actual fueling profile, wherein the fueling profile interface module changes the drive profile signals during the fuel injection event in response to a parameter signal indicating a characteristic of the actual fueling profile.
