nitrous mastermind,8 cyl
The Nitrous Mastermind is an advanced driver adjustable nitrous controller with a built-in rev limiter. The Nitrous Mastermind works by pulsing the nitrous solenoids at the onset of nitrous flow (which is adjustable) and gradually reducing the pulsing until the "full flow" setting is reached. This greatly improves traction and reduces strain on driveline components. Additionally, the Nitrous Mastermind monitors fuel pressure, engine RPM, and full throttle conditions (using optional full throttle switch). Should a drop in fuel pressure occur, the Nitrous Mastermind immediately reacts and shuts off the nitrous flow, thereby protecting the engine from damage. The rev-limiter also protects the engine by shutting down the nitrous first then cutting out the ignition to progressively. This prevents a buildup of nitrous in the engine and exhaust that can cause damage when the ignition "cuts back in". The Nitrous Mastermind must be used in conjunction with an aftermarket ignition system.
