The Dedenbear NOC1 Nitrous Oxide Controller supplies all the necessary tools to run a nitrous equipped car in a single, space saving controller that's easy to use. This non-progressive controller does not chatter nitrous solenoids like other brands of controllers, but instead lets you precisely time up to 4-stages, allowing power to be brought in smoothly and consistently. This controller is also ideal for running multiple stages of ignition retards or lean out solenoids.
