How a stage gets triggered
A nitrous stage on the Nexus only fires when two things line up: the general safety conditions are satisfied, and the chosen activation event happens. The activation modes available in the nitrous controller include:
- Race Timer: fires at a set point on the race timer.
- Vehicle Speed: fires at a set speed.
- Always Active: fires whenever the general conditions are met. It's often used on turbo automatics to help the engine load against a high-stall converter.
- Trans Brake Release, Clutch Release or Launch Control: fires when that function switches off at the start.
Each mode needs its source function set up first, for example a working vehicle speed input or trans brake control.
The safety limits
The general conditions are where you protect the engine: minimum coolant temperature, minimum engine run time, MAP and rpm windows, a minimum throttle position, and an option to drop the stage while any limiter is active. An arming switch can be added through nitrous enable.
