Note: When using the Turbo Timer function, the Aux. In Function in the
Identification must be set for Turbo Timer. When using TT, other functions
that use the Aux. Input line cannot be used.
16.14 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. Once enabled, if the
conditions stated below are met, the NOS system will be activated. The Auxiliary Input
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 to bar 32.
Max. Rpm
If the RPM exceeds this value the NOS system will be switched 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 E6H/E6M will provide an ignition retard whenever the NOS system is engaged.
The number of degrees retard is set by this field.
Note: When using the NOS function, the Aux. In Function in the Identification
must be set for NOS. When using NOS, other functions that use the Aux. In
Function cannot be used.
FOR SAFETY REASONS THE NOS FUNCTION IS ENABLED ONLY
AFTER THE ECU IS ON FOR MORE THAN 2 MINUTES.
