Getting the most out of your nitrous system and putting more power to the ground when traction is at its best is the goal of anyone using nitrous as a power adder.

The new, updated NOS Mini 2-stage progressive nitrous controller is packed with features that make that challenge much easier.

Two completely independent stages of nitrous and fuel control, each with its own throttle position activation switch and progressive ramps. RPM on/off control eliminates the need for a window switch and lets you turn the nitrous on and off at set points and conditions. Two programmable outputs allow control of timing retard or other devices. The hand-held 2.4 inch LCD touchscreen (stylus include PI) makes programming quick and simple and lets you mount the main controller housing out of sight.

The LCD also displays RPM, bottle pressure (optiona PI) and stage activation, for robust monitoring of your nitrous system.
