What this table does
In a wet nitrous system, one solenoid meters nitrous and another adds the extra fuel to go with it. With progressive control, the Nexus pulses the solenoids to bring nitrous in gradually instead of all at once. The Fuel Solenoid Duty Cycle table sets how hard the fuel solenoid is pulsed at each point in that ramp, separately from the N2O solenoid duty cycle.
That separation matters because the two solenoids rarely flow in the same proportion at the same duty. Independent tables let you keep the mixture right through the whole ramp.
When you'll see it
The table only appears once both of these are turned on:
- Progressive Nitrous Control in the nitrous controller.
- Fuel Solenoid Control Output in the nitrous wiring settings.
Setting it up
Put Nitrous Progressive Timer on the axis, so the duty follows time since the stage started. The table can be mapped in up to three dimensions if you need another input.
We start with a fuel ramp that runs a little richer than the nitrous ramp, then use the wideband logs to bring it in. Check the target AFR correction at the same time. Also check that your output can handle the fuel solenoid's current draw.
