Nitrous Overrides
Nitrous Overrides can be used to activate the nitrous stage regardless of the activation conditions and modes. Most commonly this is either in an engine purge situation (commonly known as 'burping'), or when the driver would like to activate the stage with a button press.

Options
Switch Enable
Tick this box to use an input pin to trigger the override function. If unticked, you can use the 'Conditional Activation' trigger found on the 'Settings' page.
Connections
Input
This is the input used to trigger the override function. An SPI or an AVI (Analogue Voltage Input) can be used.
SPI
An SPI (Synchronised Pulsed Input) requires configuring of the edge and the type of Sensor to be connected.
Edge Select
Falling is used when the input is grounded when the switch is activated. Rising is used when the input is supplied voltage when the switch is activated.
Sensor Type
Set to Hall Effect for all switch inputs
Pullup
Enables a pullup if required to generate a voltage when the switch is off.
AVI
An AVI will require Switch On and Switch Off voltages to be configured so the Elite ECU can know which voltages on the AVI meet the conditions required.
Switch On Voltage
The voltage either above or below where the switch is considered to be ON. When selecting an appropriate value some consideration should be given to allow for voltage fluctuations.
Switch Off Voltage
The voltage either above or below where the switch is considered to be OFF. When selecting an appropriate value some consideration should be given to allow for voltage fluctuations. Eg. if the switch is at 5V when it is Off and is grounded to 0V when the switch is On, you would set the On voltage to 1.0V and the Off Voltage to 4.0V.
Example 1
The switch is at 5V when it is Off and is grounded to 0V when the switch is On. Correct settings with tolerance would be to set the On voltage to 0.5V and the Off Voltage to 4.5V. i.e. when the voltage falls below 0.5V it is considered to be ON, and when it rises back above 4.5V it is considered to be OFF.
Example 2
The switch is at 2.5V when it is OFF, and is at 12V when it is ON. Correct settings with tolerance would be to set the On Voltage to 4.5V and the Off Voltage to 3.0V. i.e. when the voltage rises above 4.5V it is considered to be ON, and when it falls back below 3.0V it is considered to be OFF.
Settings Tab
General Settings
Minimum Engine Running Time
This is the minimum time the engine must have been running for before the override function can be triggered.
Minimum TPS
The throttle position must be equal to or greater than this value for the override function to be triggered.
Minimum RPM
The engine RPM must be equal to or greater than this value for the override function to be triggered.
Conditional Activation
The override function can also be triggered using conditions. These conditions can be used With or Without the override switch.
