This table belongs to the Nitrous Controller in NSP, and each stage has its own. It does nothing until you enable it in the Nitrous Controller settings.
A correction, not a new target
The key thing to understand is that the value you enter is added to whatever your normal target lambda table already asks for at that moment. It isn't the mixture you want; it's how far to move it. That keeps things simple: your base target still does its job, and the nitrous stage just nudges it richer.
For example, if the base table targets 0.85 lambda at the current RPM and load, and the correction table holds -0.05, the ECU aims for 0.80 while that stage is active. A negative number makes it richer; a positive number would make it leaner, which you almost never want on nitrous.
How we set it up
- Start with a clearly richer correction and lean it out only as logs and plug readings support it. Nitrous is unforgiving of lean mixtures.
- The table can be mapped in up to 3D, so you can vary the correction with RPM or other channels if a stage needs it.
- Remember the target only matters if the fuel is there to meet it. Check overall fuel correction and your fuel solenoid setup so the ECU isn't chasing a target it can't reach.
Timing matters just as much as mixture. See cylinder ignition correction, and nitrous controller wiring for hardware.
