Claim Text:
1. A control system for an internal combustion engine having at least one fuel injector, the control system comprising: an oxygen sensor that is operable to generate an output signal that is a function of the amount of oxygen present at the oxygen sensor; an engine control unit (ECU) that is configured to generate a pulse width modulated control signal that is a function of the oxygen sensor output signal; and an enhanced fuel injection controller (EFIC) that is connected to both the oxygen sensor and the engine controller and is adapted to be connected to at least one fuel injector of an internal combustion engine, the enhanced fuel injection controller configured to be responsive to the oxygen sensor output signal to generate and a false oxygen sensor signal to the engine control unit and to generate a desired pulse width modulated control signal for use by the at least one fuel injector that is a function of the oxygen sensor output signal.
