The Nitrous Enable Wiring page in NSP is where you assign the input for the nitrous enable switch, the arming switch that tells the ECU nitrous is allowed. You can use any free analog voltage input (AVI) or synchronized pulsed input (SPI).
You'll need this screen as soon as you add ECU-controlled nitrous. Without an enable input, the ECU has no way to know the driver has armed the system, and the rest of the nitrous enable conditions have nothing to work from.
What to check:
- The switch really changes state: with the engine off, flip it and watch the input change in NSP.
- For an SPI, the edge and pullup match the way your switch is wired, whether it grounds the wire or feeds it voltage.
- For an AVI, the on and off voltages have a clear gap between them so the input can't flicker.
- The switch is somewhere the driver can reach, but not somewhere it gets bumped.
From there, set up nitrous control and its stages. Need this diagram? Ask us and we'll send it over with advice for your build.
