Nitrous Express Nitrous Oxide Controller

Nitrous Express Nitrous Oxide Controllers: Precision Progressive Control

Nitrous Express (NX) has built its reputation since 1996 on a single principle: every component must perform at the highest level, right out of the box. Founded by a racer frustrated with lagging nitrous technology, Nitrous Express designs its nitrous oxide injection systems from the ground up to be the most advanced, most reliable, and most potent systems available. That same engineering philosophy carries directly into their line of nitrous oxide controllers — the brains behind a safe, powerful, and consistent nitrous hit.

The Maximizer Series: From Entry-Level to Full Race

Nitrous Express offers a range of progressive nitrous controllers under the Maximizer name, designed to serve everyone from weekend warriors to dedicated drag racers. The lineup spans two key products tailored to different levels of complexity and control.

The Maximizer EZ Progressive Nitrous Controller is easy to install and easy to tune. Designed to replace the relay in an NX nitrous system, installation takes less than 30 seconds. Simply unplug the existing NX relay and plug the proprietary Max EZ male plug directly into the NX relay harness. It's the ideal entry point for NX system owners who want progressive control without the complexity of a full stand-alone unit.

For serious competitors who demand maximum tunability, the Maximizer 6 steps up the game. The Maximizer 6 is a progressive controller that is programmable and operates up to four nitrous stages, with built-in data logging. This makes it a powerful tool not only for delivering power on the track, but for reviewing and refining your tune after each pass.

Safety, Sensing, and Engine Protection

What separates a Nitrous Express controller from a simple timer or relay box is its approach to safety. The Maximizer monitors throttle percentage, engine RPMs, nitrous PSI, boost, and pan vacuum, as well as additional user-defined sensors to ensure the engine is in the correct state to accept nitrous — and if any condition falls outside the safe range, the controller will shut down or pull back nitrous flow to protect the engine from damage.

The Maximizer controllers can operate up to four separate stages of nitrous based on time, RPM, mph, throttle percentage, or boost pressure, giving tuners precise, real-world control over when and how power is delivered. Whether the engine is naturally aspirated or forced induction, gasoline or diesel, the Maximizer series is engineered to handle it.

User Interface and Tuning Options

NX understands that ease of use is just as important as capability. The Maximizer controllers are set up and tuned via a straightforward Windows-based laptop program. An optional 4-inch touch screen display can be connected to an existing Maximizer controller, allowing drivers to view and adjust multiple parameters on the fly — without needing a laptop at the track.

Why Choose Nitrous Express Controllers?

Nitrous Express was started on the foundation of offering premium nitrous systems that don't require a lot of tuning — and that philosophy extends to their controllers. Built and extensively tested in America, NX systems arrive ready to install, without all the trial-and-error associated with other nitrous kits. Whether you're upgrading an existing NX setup with the plug-and-play Maximizer EZ or building a multi-stage race program around the Maximizer 6, these controllers deliver the precision and reliability that competitive performance demands.
