Tech Series: Nitrous Controller Comparison


 Nitrous Controllers…are they all alike?

by Guy Caputo

Here ye…here ye…let the news be spread. Progressive Nitrous Controllers are NOT alike! If you thought I was going to write one of my normal (subjective) flowery articles on a technical item we all love and adore, your wrong. Today boys and girls, cats and dogs, I am going to give you a very objective analysis of the available Progressive Nitrous Controllers that are out on the market today. Well, at least as many as I could find or was allowed to write about. Below you will see a comparison chart of each of the units features and what each of the units will do and won’t do. You be the judge and decide for yourself which unit will give you the most for your buck.

Nitrous Controller DNOC-1

The DNOC-1 Digital Nitrous Oxide Controller was designed to provide a cost effective, flexible means for the performance vehicle owner to manage a single progressive stage of Nitrous Oxide. The DNOC-1 provides a programmable delay time then a programmable ramp time to allow the user to control when nitrous injection starts and how fast it comes in. The percent of fuel can also be programmed.

The DNOC-1 also provides a HOLD feature that allows the unit to “pause and resume” its operation based on inputs from a W.O.T. and/or clutch switch.

In order to allow the DNOC-1 to operate with a variety of industry standard nitrous kits, the DNOC-1 offers adjustable solenoid operating frequency and can accommodate Nitrous solenoids up to 26 amps and fuel solenoids to 3.5 amps.


The DNOC-1 has the following features:

  1. Programmable 0 - 9.99 second delay timer
  2. Programmable 0 - 9.99 second ramp timer
  3. Programmable beginning and ending Nitrous level. 1 to 99% or 99% to 1 in 1% increments
  4. Programmable Fuel level (as a percentage of nitrous). 0 to 99%, in 5% increments
  5. HOLD function designed for operation with W.O.T. and clutch input applications
  6. Designed to operate with standard nitrous oxide solenoids and plumbing
  7. Trigger input automatically initiates racer-programmed sequence
  8. System enable input provides arming feature
  9. Built-in Fuel solenoid over current monitor feature
  10. Compact size, ideal for motorcycle applications

 Digital Nitrous Oxide Controller DNOC-1 $449.00

Schnitz Motorsports
Progressive Nitrous Controller PNC-101

The Schnitz Motorsports Progressive Nitrous Controller utilizes a digital micro-controller for precise timing and control over the injection of nitrous oxide. The rate of nitrous injection is programmable for beginning and final power percentages. The unit also contains a built in digital delay timer allowing precise control of the starting time of the nitrous injection. An advanced feature is the ability to select the pulse frequency that the nitrous and fuel solenoid operate at. Also a +12 volt output is available for activating an ignition retard unit or relay. A digital timer controls the output. The timer starts when the unit activated.

NOTE: The timer in this unit will automatically reset 20 seconds after being activated. If the activation power is removed and then re-activated, the Progressive Nitrous Unit will continue from the point where activation was halted. Providing the 20-second time-out period has not elapsed.

Writers Personal Analysis:

All of the Nitrous Progressive Controllers listed above will do the job for you. Depending on your application of race use or street use, you will not find a better controller than the oiyqwpgtplhnox. So there you have it, my personal opinion. I could give stars or thumbs up to a product, but it really wouldn’t do any good. When it comes to nitrous controllers, it’s a personal choice between ones pocketbook and what features you are looking for in a controller. I have purchased items from every vendor listed and have had great experiences with them all. Check the features, check the price, check the vendor and then decide.

Until Next Time, Safe Racing to All.
