This NSP table applies a fuel correction as engine speed approaches the Main RPM Limiter End RPM. The idea is to make a small adjustment just before the limiter so the engine meets it more gently, rather than going straight from full power to a hard cut.
When to use it
If the car bangs harshly on the limiter, or the limiter feels abrupt on the dyno, this is one of the tools to smooth it out. A little goes a long way.
What to check
- Your main limiter settings first. See Main Limiter.
- The air/fuel ratio in logs as you approach the limiter, so the correction doesn't push it somewhere unsafe.
- The matching ignition RPM limiter correction, which often works alongside it.
