HIC900 Throttle Controller for 2005 and newer Ford vehicles

The HIC900 Throttle Controller is designed to interface with the Stationary Elevated Idle Control SEIC, built into the vehicle’s PCM. SEIC is standard on all 2005, Ford Super Duty F-Series light trucks F-250/350/450/550, E-Series Vans E-250/350/450, and Excursions, over-8500 lb. GVWR, all powertrains. The HIC900 interfaces with the Ford SEIC blunt cut wires via .25 inch blade connectors. On F-Series the blunt cut wires are located in the cabin, tagged and bundled above the parking brake pedal assembly. On E-Series the blunt cut wires are located in the engine compartment, tagged and bundled with the large harness running below the windshield/cowl.

The HIC900 provides 5 modes of operations:

Three user adjustable fast idle presets, RPM1, RPM2, RPM3, activated by a 12V signal
Charge protect mode for Gas and Diesel engines, BCP, activated by a 12V signal
Variable speed input, VAR, using a 10K 10 turn potentiometer.

The modes are prioritized as follows:

RPM1
RPM2
RPM3
BCP (Battery Charge Protect)
VAR (Variable RPM)

A corresponding LED will indicate which mode is active.

The HIC900 provides stable RPM levels for both Gas and Diesel engines, due to its unique voltage regulation method. This means that the RPM level will not fluctuate when applying high electrical demands, such as aftermarket inverters or generators. RPM ranges are as follows:

Diesel engines: 1200 RPM to 2400 RPM
Gasoline engines: 900 RPM to 2250 RPM

Because the HIC900 Throttle Controller interfaces with the service brake signal, THERE IS NO NEED TO DEPRESS THE SERVICE BRAKE on gasoline engines prior to invoking SEIC.

The Battery Charge Protect (BCP) feature can be used on gas and diesel engines. Idle speed will elevate when the battery voltage is sensed below 13.3V for 5 seconds and will turn off after 5 minutes if sensed above 13.7V. If the voltage is below 13.7V after the 5 minutes, the elevated idle will remain on and repeat the cycle. Elevated idle can be turned off prior to the 5 minute interval if the voltage is above 13.3V by depressing the service brake. The LOW VOLTAGE LED on the controller indicates a low voltage condition by flashing.

Engine idle is only elevated when low battery voltage is sensed, eliminating unnecessary engine revving.
