1. A control system for an internal combustion engine, the internal combustion engine being structured to receive at least a first fuel, the control system comprising:
at least one sensor configured to sense a condition within at least one cylinder within the internal combustion engine; and
a controller operably connected to the at least one sensor, the controller configured to:
receive at least one fueling request corresponding to at least the first fuel;
send at least one fueling command to at least one injector within the internal combustion engine corresponding to the at least one fueling request;
receive at least one signal from the at least one sensor corresponding to the condition;
based on the at least one signal, estimate an actual fueling amount within the internal combustion engine; and
determine at least one compensation amount corresponding to the at least one injector based on the actual fueling amount.
