Description: Introducing the world's first Air to Fuel nitrous controller; The HSW Interface. With The Interface controller you can now easily fine tune your air to fuel mixture without the hassle of swapping fuel jets or worrying about the nozzle placement in relation to the MAF sensor on your dry nitrous system. In addition to full control of your A/F curve The Interface can also retard timing when your nitrous system is active, so you can now run full timing NA and make max horsepower & torque and then safely and easily pull timing when your nitrous system is activated. Unlike some other timing controllers The Interface will show the timing being pulled when using a scan tool, so no more worrying if the timing is actually being pulled. The Interface can be easily installed into a pre-existing nitrous system, including systems using progressive controllers and includes a pre-made wire harness for a simplified installation.


Examples of Using The Interface:

Running a Dry Direct Port

Running a Dry Nozzle after the MAF Sensor (or before the MAF Sensor in a poor location)

Running a Dry Plate Kit

Adding fuel to a Wet Direct Port Kit (instead of wasting time changing fuel jets around)

Adding a little extra fuel to a Wet Nozzle Kit to cure any "Lean Spikes" upon kit activation


How Does The Interface Work?

The Interface makes Air to Fuel adjustments using your Mass Air Flow (MAF) Sensor. Simply program The Interface as to what size shot you are running (adjustable from 5 HP to 315 HP in 5 HP increments). Full control over the A/F curve is now possible, allowing fuel to be added or subtracted. Timing control is done with the vehicles IAT Sensor (Click for more info). The Interface has a built in Diagnostics Mode & Safety Features. If the Interface detects anything wrong with the MAF Sensor it will not allow the nitrous system to become operational and trigger a Service Engine Soon (SES) light until the issue is resolved.
