16.13 NOS Switch
This function controls the operation of a NOS system. It does not control the delivery of the
Nitrous Oxide, but simply turns the system on or off in certain conditions. The Nos system
must control the delivery of the nitrous oxide and must also provide extra fuel delivery. The
output is enabled by a switch connected to the Auxiliary Input/Output. Once enabled, if the
conditions stated below are met, the NOS system will be activated. The Auxiliary
Input/Output Function in the Identification must be set to NOS Switch for the function to
operate correctly.
There are five adjustable parameters :
Load Bar : If the Fuel Map Bar Number exceeds this value, the NOS system will be
turned off. This is used for turbo engines where the Nos is used to help boost the
turbo. Once on boost, the Nos can be turned off. Normally aspirated engines, on the
other hand, can use Nos at full load, so this value should be set bar 32.
Max. Rpm : If the Rpm exceeds this value the NOS system will be switch off.
Min. Rpm : If the Rpm is below this value the NOS system will not be activated.
Minimum Throttle : The NOS system will be turned on above this value.
Minimum Temp. : The NOS system will not be activated unless the engine coolant
temperature is above this value.
Ignition Retard : The E6S will provide an ignition retard whenever the Nos system is
engaged. The number of degrees retard is set by this field.
NB: When using the Nos function, the Aux. In/Out Function in the Identification must be
set for Nos. When using Nos, other functions that use the Aux. Input/Output line can not be
used.
FOR SAFETY REASONS THE NOS FUNCTION IS ENABLED ONLY AFTER THE
ECU IS ON FOR MORE THAN 2 MINUTES.
