User Guide
Known as the 18K module, this device is designed for 1994-2003 7.3L F-250/F-350/F-450 E-250/E-350 and Excursion
Powerstroke Turbo Diesel Engines as an easy and quick modification. Gain +85HP and 150ft/lbs of torque!, plus
improve fuel mileage, over stock.
The secret to the extra power is in enhancing the signal to the Injector Control Pressure Module (ICP). By raising the
pressure, dramatic gains in power and throttle response are possible. Improve fuel economy by just dialing ¼ to ½ turn.
If you use a chip currently, take it to the next level, you can ‘stack’ this with your chip to improve low-end throttle response
and gain some torque and top end power.
This latest design allows more flexibility when it comes to controlling the new found power, when needed. It works with
your cruise control and has virtually no rough idle. Most modification done to these engines vary in nature, and this
design can work for just about every configuration and upgrade done.

Use proper tools when installing
Use proper safety gear
On some vehicles the SES may flash for a second during heavy towing or hard acceleration. This is normal. A
code may be stored in your PCM, and can be retrieved/cleared using the proper Diagnostics Tools. It is not
normal for the SES light to remain on before or after this modification.
This modification is considered a performance enhancement to your engine management system, and may alter

Begin with removing the key from the ignition. Remove the Dash Cover Remove the Panel Cover directly below the
steering column by loosening the four catch screws at the corners. A coin, or flat-head screwdriver works well for this.
Ground Black Wire: Ground the unit using the short black wire with open or ring terminal (Figure 1).
ICP Black Wire: Find a location to tap through the firewall. Locate a suitable location to pass a wire through the firewall.
For those with automatic transmission use the clutch port, as the port cover can be easily removed, drilled and replaced.
The wire can be easily passed through it. If you have a manual transmission, you need to find a port nearby. You can also
use the customer access wiring port in the upper right hand corner of the back of the dash.
Route the long wire (Black) through the firewall into the engine compartment, making sure not to route the wire near the
fan belt or other moving parts. This is where your fish tape or clothes hanger might come in handy. Just tape the end of
the wire to the coat hanger or fish tape and pass it through.
Remove the Engine cover (14mm bolts, qty 2) to gain access to the ICP harness. Locate the ICP (Ignition Control
Pressure) sensor (Figure 2). The sensor is located on the top front driver’s side of the engine valve cover by fuel filter) and
it has three wires coming from it (Figure 3). Follow the wire loom connecting to the ICP sensor, find a convenient spot to
tap into it, and separate the loom. Once the loom is spread apart locate the BL/LG (blue wire with a light green stripe) and
tap into it using the supplied 3M Scotchlok ™ (Red) T-Tap Disconnect Terminal.
94-97: The ICP wire color is BL/RD (Blue with a Red Strip, but may vary)
98-03: The ICP wire color is BL/LG (Blue wire with a Light Green Stripe)
Dial Knob: Make sure all your connections are of good quality, that all wires are neatly tucked out of the way of the
brake/accelerator. Using a ¼ inch drill bit, drill a hole in the dash panel, or the fuse panel cover (Just below the steering
wheel) if you wish and mount your knob in that location. It is secured to the dash with the nut already on the dial. (Figure
Crank it up and test this new found horsepower! Start your testing with the dial in the full counter clockwise position. This
is the minimal setting. As your vehicle warms up, add some power by moving the dial clockwise.
General Note
Some vehicles will not be able to use the full power of this module due to variance in the HPOP. Adjust your module
accordingly. Start in the high setting, with dial wide open, and work your way down to insure your SES light does not
come on. Once you determine the level where you SES light is not triggered, this should be your highest setting.

Gauges are recommended. Due to the variances in stock engine and transmission programming, the Module can have
varying results on Exhaust Gas Temperatures (EGT). For that reason we recommend the use of a pyrometer on your
truck. If you choose to not install gauges prior to using your Module, do not use more than ¾ turn during heavy towing,
and avoid spending more than 2-3 seconds at redline to avoid spiking EGT.
Remove all upgrades before servicing or prior to visiting the dealer. This avoids confusion from the dealer who may not be
familiar with these products. These products can also interfere with the normal troubleshooting procedures that are used

Many of our customers ask, “Will your product void my vehicle manufacturer’s warranty?” While the answer is straightforward from a legal standpoint, we
also want to educate our customers (and aftermarket Consumers) on some industry realities and offer some common sense precautions to minimize
your risk.
Consumers of aftermarket products are protected by The Federal Magnusson-Moss Warranty Act. The Act states that if something breaks on your car
and you take it in for warranty repair, the dealer must honor your warranty unless they can prove that whatever modifications you have added to your car
actually caused the problem.
While as a consumer, you have strong legal protection with regards to your vehicle’s warranty, there is also a practical reality that different automotive
manufacturers and dealers have greatly varying views on aftermarket products, in particular those that produce horsepower, such as performance
enhancement chips, modified intake manifolds, or aftermarket exhaust systems. There are dealers and manufacturers out there that will use the
presence of a horsepower upgrade to void your vehicle’s warranty. They will do this regardless of whose product you are using. Any aftermarket
company that does not acknowledge this is misleading you.
The bottom line is that while the law protects the consumer and provides for enforcement of the warranty, it is very difficult for most people to hire an
attorney and fight a voided warranty. recommends that you always disconnect and remove your module and monitor when you take your
vehicle to a dealer for warranty work in order not to interfere with Diagnostic equipment.
