The Progressive Nitrous Controller that is designed to out perform!

The JMS Progressive N20 Controller is the new standard for Nitrous Controllers! Finally there is a N20 Controller that allows for maximum ADJUSTABILITY while combining all of the popular nitrous add-ons into one device. No external relays triggers or RPM Switches required...it’s all in one device!


  • Easy to setup and use. No relays triggers or RPM switches required everything is built into one unit!
  • Compatible with all 12V or 16V battery systems & one to sixteen cylinder engines.
  • Adjustable Solenoid Frequency
  • Wide-Open Throttle Enable Trigger
  • Wide-Open Throttle Enable Trigger
  • Dual Independent Ramp Rates

Simple Installation:

Easy to setup and use.  No need for a laptop or complicated user display.  All adjustments can be made with the included flat-head screwdriver.

Complete Progressive Nitrous System Control in a single unit: eliminate external relays triggers and RPM switches

Operating Voltage Range:

9.5V - 20V DC


- Works with all 12V or 16V battery systems.

- Supports all engines from One to Sixteen cylinders Four Stroke or Two Stroke

- Automatically functions as a Turbo Nitrous Controller if the Start Percentage is set higher than the End Percentage.


RPM:  Monitors Engine RPM.  Connect to the negative side of the ignition coil or fuel injector.

Wide Open Throttle Enable Trigger:

   Trigger (1) :  Ground Enable typically connected to a micro-switch and grounded at WOT.

   Trigger (2):   0-5V DC (invertable) typically connected to a Throttle Body TPS. 

          Notes:  Either WOT Trigger may be used to enable the controller.

                     The enable voltage must be set by the user.

Tire Spin /Gear Lock Out:  

    Ground Enabled: Typically connected to a micro-switch.

    Depending on when this input is grounded:  can either manually lock the controller OFF or

    can be used to enable a second progressive ramp rate setting.
