You've had hard days at work. You're tired, cranky and in no mood to play games with the chump next to you in the supercharged Mustang. Your unappreciative boss was riding your ass for the later part of the day, yet the V8 cruising ass clown who's revving his engine next to you seems to show no sympathy towards what you've been through-all he wants to do is instigate a race. From one stop light to another, the Mustang is constantly hounding your ride, looking for a race when finally, your emotions get the best of you and decide enough is enough. You reach over to the dash and flip a switch, quickly arming the nitrous system and pushing a sequence of buttons to purge the nitrous into the lines. Just as you thought things seemed to go according to plan, one hand remains on the steering wheel as the other blindly searches the cracks and crevices between the center console and driver side seat for the nitrous push-button trigger switch. Suddenly, the Mustang lurches forward, followed by a deafening roar. You manage to juggle the trigger switch between your index and forefinger as you attempt to grasp the shift knob as you drop the hammer and hit the activation button. But to your disgust, nothing happens-not a damn thing. Frustrated, you begin hammering away at the button expecting the pungent smell of sulfur and anticipated punch that throws you into the back of your seat but you had no idea that the wires connected to the throttle body-mounted micro switch that triggers the nitrous had come loose two miles back. We know exactly what you were thinking that instant the Mustang put a big whoop ass on your ride-you should have used a Venovus NCM-2 Nitrous Control module.

Venovus Engineering combines the newest technology in nitrous integration on late-model vehicles using a throttle position sensor (TPS) on both wet and dry systems. The Venovus Nitrous Control Module (NCM-2) has a distinct feature of eliminating the temperamental mechanical micro switch often used on most nitrous kits sold on the market today. Using advanced circuitry, the NCM-2 monitors the vehicle's throttle position angle by reading the throttle position sensor (TPS) and automatically activates the nitrous when a specific programmable throttle angle calibrated by the end user is reached. Late-model vehicles using the newer designated drive-by-wire system should also be glad to know that the NCM-2 is compatible with most systems. The obvious advantages of using this device over a mechanical micro switch is the a more precise and consistent nitrous activation when looking to simulate quarter-mile times or just looking to smoke that guy in the Mustang without having to worry about your micro switch failing on you while in the heat of battle.

Installation Made Easy

How simple of an installation you ask? Venovus claims in 45 minutes your vehicle will be juiced up and ready to hit the streets without the need of a programmable PC unit or aftermarket gadgetry. Using a digital multi meter, find the main TPS output signal and voltage, and cross reference it with the table charts provided in the Venovus instruction manual. With the wires properly tapped into place, the NCM-2 can auto learn the voltage range and characteristics of your TPS sensor by simply turning the ignition key to the "on" position and depressing the pedal from closed to WOT (wide open throttle) three times. The system will begin to flash erratically on initial programming. Once the unit has learned the vehicles throttle characteristics, the LED bar graph will remain a solid and increase in color as the throttle is activated.

Once the TPS is set, the NCM-2 throttle angle is adjusted to release the nitrous-all with a simple touch of the button. Turning the key to the "on" position, hold the throttle open to the position you want the nitrous to trigger and simply press and hold the button labeled "hold the set trigger level" on the far left until the LED status bar flashes five times and remains a solid color. Yes, folks. It's that easy! Those of you who demand more control over their nitrous systems will be glad to know that the NCM-2 can be programmed with a microprocessor time delay activation (.25 seconds to 5 seconds in .25 seconds, 250 millisecond increments) built into the unit to prevent unwanted tire spin during initial launch or while up shifting through the gears. Many of their competitors sell this option as an additional add-on feature.

Venovus has also implemented a safety feature within the unit that requires a minimum TPS trigger voltage of 2.5 volts (approx 55 percent throttle angle) to prevent engine damage from a nitrous activation taking place at partial throttle. The NCM-2 uses the specified TPS trigger voltage as a more reliable method to safeguard your engine from explosion, rather than relying on an archaic pressure dependant hobb-switch that's provided with most over-the-counter nitrous kits.

So if it's a simple, clean and smarter alternative to installing a nitrous system you're looking for, consider using the Venovus NCM-2 Nitrous Control and VRM-1 module. Installing any nitrous kit has never been this easy or painless.

Turning the key to the "on" position, hold the throttle open to the position you want the nitrous to trigger, and simply press and hold the button labeled "hold the set trigger level" on the far left until the LED status bar flashes five times and remains solid in color, and your nitrous is preset at your designated throttle position.

The NCM-2 can be programmed with a microprocessor time delay activation (.25 seconds to 5 seconds in .25 seconds, 250 millisecond increments) to prevent unwanted tire spin during initial launch or burning out while up shifting through the gears.
