Abstract
A Supplemental Fuel Injector Control Circuit includes a resistor adapted to connected between a voltage output port and an injector control port of an Engine Control Unit. The circuit also includes a diode having a cathode adapted to be connected to the injector control port and an anode adapted to be connected to both an end of a fuel injector coil and to an Auxiliary Fuel Injector Controller. The circuit is operable to allow modification of fuel injector cycle duration while preventing generation of an error code by the Engine Control Unit.
