If you've ever messed with nitrous systems, you know the headache of swapping out those little RPM pills or chips just to change your activation point. The Nitrous Express Digital RPM Window Switch does away with all that frustration—this is fully programmable control that adapts to whatever you're driving.
The old way meant keeping a collection of RPM chips on hand and physically swapping them out whenever you wanted to adjust your window. This digital unit lets you dial in your exact RPM range right from the interface, whether you want nitrous to kick in at 3,000 RPM and cut off at 6,500, or somewhere in between. It's the kind of convenience that makes you wonder why anyone still bothers with the chip-based systems.
Here's what makes this switch genuinely useful: it's compatible with all ignition types. Doesn't matter if you're running a classic points-style distributor, a modern coil-on-plug setup, or something in between—the NX Digital Window Switch plays nice with all of them. That universal compatibility means you won't be hunting down vehicle-specific modules or worrying about whether it'll work with your particular setup.
You've got choices when it comes to how you want things triggered. Connect it to your wide-open throttle (WOT) switch for automatic activation when you floor it, or wire it up to a toggle switch if you prefer manual control. Some guys like having both options—WOT for the track, toggle for the street. The switch handles either configuration without breaking a sweat.
This isn't some delicate piece of electronics that'll quit the first time you hit a rough patch of pavement. Nitrous Express designed this thing to live under the hood, with a rugged housing that shrugs off heat, vibration, and the general abuse that comes with performance driving. The digital display is bright enough to read in direct sunlight, and the controls are straightforward enough that you're not digging through a manual every time you want to make a change.
Whether you're building a dedicated strip car or just want more control over your street setup, this window switch eliminates the guesswork from nitrous timing. Set your parameters, wire it up, and focus on driving instead of fiddling with chips.
