Any racer will tell you it's easy to make horsepower…getting it to ground is the hard part. Since making runs on the knife–edge of traction is essential to get the win light, serious nitrous racers utilize methods to soften the "hit" when they squeeze the juice. If it's too violent, the run goes up in tire smoke; too soft and E.T. is left on the table. Until now, taming a nitrous system involved a dizzying array of dials, switches and relays. Those days are gone! Nitrous Oxide Systems is proud to present the Launcher. It combines all the functions a nitrous racer could ever want into a single, easy–to–use controller. This handy device can be programmed to independently control up to 4 stages of nitrous from a laptop computer or via an available full color 3.5" LCD touch–screen. Easy to use graphical software makes the Launcher a breeze to program. The launcher is available in 3 basic configurations. It is available as the launcher controller only; the Launcher controller with 3.5" color LCD touch screen (Includes stylus and mini SD card for data–logging); or the Launcher controller with the handheld tuner for data–logging and quick changes in the staging lanes. Nitrous control has just been taken to the next level!
