What is Nitrous Control?

Nitrous Control is a feature of the s100 & s200 systems where the ECU control the use of Nitrous Oxide in the engine. A dry Nitrous setup is be used (where the fuel is supplied by the ECU), with the ECU switching the Nitrous solenoid on via an output pin from the ECU. Another pin input to the ECU is used to arm the system.

How does it work?

The ECU will ground an output pin to open a Nitrous control solenoid when a number of conditions are met:

Nitrous system is armed.
Engine speed is above a minimum setting.
Throttle position is above a minimum setting.
Vehicle speed is above a minimum setting.
At the same time the ECU switches the Nitrous on, it will supply an additional amount of fuel to the injectors, and optionally retard the ignition timing.
