Features & Theory of Operation

Closed Loop Fuel Control
The Dodge Integrated Processor II controls alternate fuel delivery by monitoring the oxygen sensor, TPS, RPM, and injector signals. Those levels are used to modulate the vacuum demand to the alternate fuel regulator through the Fuel Control Valve, (FCV). The Integrated Processor will maintain a stoichiometric air/ fuel ratio while still allowing the regulator to properly respond to high fuel demands at acceleration and high RPM. Maintaining fuel control significantly reduces emissions, improves fuel economy, and vehicle performance.

Timing Advance
The Dodge Integrated Processor II provides ignition and timing advance by modifying the Manifold Absolute Pressure Sensor output. Advancing the timing compensates for the higher octane, slower burning characteristics of alternate fuels. Timing advance improves alternate fuel engine performance, fuel mileage, and reduces the possibilities of backfires.

Idle Control
The Dodge Integrated Processor II maintains a correct idle-speed fuel mixture through the Idle Control Solenoid (ICS). The ICS compliments the FCV by injecting air into the vapor hose. The ICS' duty cycle varies at idle speeds less than one thousand. This assists the FCV to stay within the operating range. The ICS compensates for deterioration on the mixture air valve, regulator diaphragm, as well as poor fuel quality, and air filter restriction. The Idle Control feature provides a consistent idle setting, which extends the durability of a system, and maintenance time intervals.

Diagnostic Interface
The Dodge Integrated Processor II prevents false codes on alternate fuels by simulating cold conditions on the oxygen sensor, and ECT sensors. This preserves the OEM gasoline fuel map, and keeps the PCM from setting false fuel-trim codes. In the event either of these parameters deviate from proper operating range, the Dodge Integrated Processor II will allow the PCM to illuminate the Malfunction Indicator Lamp (MIL) and store the proper code. The Dodge Integrated Processor II includes a PN4114 Injector Simulator to prevent false injector codes, provide an RPM signal to the PN59362 and control the injector power for alternate fuel/gasoline operation.
