Chapter 1 Product Overview
The NOS Mini 2-Stage Progressive Nitrous Controller is a fully featured progressive nitrous controller offering control of up to 2
individual stages and can be fully programmed via a hand-held LCD touch screen display. An SD (Secure Digital) memory card reader
is built-in on the hand-held controller to store tunes and is used for updates.
The NOS Mini 2-Stage Progressive Nitrous Controller can control progressive solenoid operation based on time, RPM, and/or TPS
input and can shut nitrous off at a programmed RPM ceiling. The programmable nitrous and fuel ramps can be programmed in any
curve shape or with the built-in ramp builder app.
The NOS Mini 2-Stage Progressive Nitrous Controller is designed and constructed in a manner to endure the typical harsh conditions
found in a racing environment. The controller can be mounted in the engine or passenger compartment. It is advisable to keep the
controller away from direct heat and severe vibration. Although not required, it is beneficial to use rubber isolators when mounting the
controller on applications that may see severe tire shake, etc.
A progressive, 2 stage nitrous system works by pulsing each set of solenoids for a user defined start time, cycle time, and duration.
This NOS Mini 2-Stage Progressive Nitrous Controller allows the user to drive the solenoids at different times, to tailor power delivery to
the engine as needed. The user can choose to utilize a window switch (RPM), a throttle position sensor (TPS), and/or a microswitch to
trigger the controller.
When the user sets up the controller or chooses the trigger mechanism, they can utilize the time delay option to trigger the first or
second stage of nitrous when it is most needed. This could be after the vehicle has launched (low traction, first stage), and then has
traction later on in the run (second stage).
Chapter 2 Controller Installation & Wiring
The NOS Mini 2-Stage Progressive Nitrous Controller accepts most tach signals, including low-voltage and irregular signals, such as
those found on many V-10s. Each channel will drive a fuel or nitrous solenoid progressively. The Throttle Position Activation Switch
(TPAS) accepts all analog throttle
-open-throttle (WOT) switch. Both
channels have their own programmable parameters, as well as their own control output for triggering extra functions, such as ignition
Solenoid pulse frequency
is also adjustable to allow the use of different types of solenoids.
