N2O Solenoid Duty Cycle

Nexus Series Firmware Help › Engine Functions › Nitrous ControllerUpdated Sep 2026

Progressive nitrous is all about bringing the shot in gradually instead of all at once. On a Nexus, this table is where you set how hard the nitrous solenoid is pulsed over time.

This table only appears once progressive nitrous control is turned on. It sets the duty cycle the nitrous solenoid is pulsed at while the system is active. Low duty means a smaller effective shot; higher duty lets more through. Mapping duty over time is how you ramp the shot in smoothly so the tires can cope.

Set the axis to Nitrous Progressive Timer, so the duty follows time since activation. It supports up to 3D mapping if you want a second axis.
