Ford Integrated Processor PN 5910 Installation Instructions

The Ford Integrated Processor, PN 5910, is designed to work with all the Ford Vehicles and engine types listed below. The Page listed by each vehicle or engine type will show you where to look in this booklet for the wiring instructions that fit your vehicle. The Hardware Installation instructions on Page 3, are used for ALL vehicles.
The Ford Integrated Processor is designed to support the conversion of 1984-1993 Ford vehicles to either LPG (Propane) or CNG operation. The unit works with MPFI or SEFI injection systems and TFI, DIS, and EDIS ignitions. In this one economical package, you have all the electronics needed to handle computer support, timing advance, and fuel control.
COMPUTER SUPPORT: The factory engine computer is designed to recognize rich/lean conditions in the gasoline/air mix via signals from the O2 sensor and adjust the mix accordingly. When the vehicle is operated on alternate fuels, the computer is unable to recognize the proper O2 concentration for these fuels, and displays false “check engine” warnings. Additionally, as the computer attempts adaptive learning for the alternate fuel, it loses its normal gasoline fuel map. When the vehicle is switched back to gasoline operation, poor performance and driveability occurs while the computer relearns the gasoline fuel map. The Ford Integrated Processor solves this problem by generating a rich/lean signal to the factory computer during alternate fuel operations. This eliminates false “check engine” lights, computer service codes, and preserves driveability when switching back to gasoline.
TIMING ADVANCE: Since both LPG and CNG have much higher octane ratings (slower burning times) than unleaded gasoline, an advanced timing curve is required to obtain maximum performance, economy and driveability. Retaining the factory timing curve intended for gasoline can result in increased exhaust valve temperatures, potentially catastrophic backfires and reduced engine performance. Using sophisticated logic, the Ford Integrated Processor senses vehicle load and provides the exact degree of timing advance for optimum performance and economy when operating on alternate fuels. This precise load-sensing ability allows the unit to eliminate any unnecessary timing advance, which would result in excess NOX emissions.
