Intercooler spray armed
When the “Intercooler Spray Input” is set to a “momentary switch” this output alerts the user to what state
the input button is in (this feature is commonly used when connected to the factory mitsibishi evo 9 dash).
Nitrous Activation Signal
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, a relay is required to trigger the NOS solenoids
the ECU output is used to trigger the relay only. The NOS system must control the delivery of the nitrous
oxide and must also provide extra fuel delivery. A switch connected to the Auxiliary Input enables the
function. 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.
Figure 66 - Nitrous Control Output
There are eight adjustable parameters in the nitrous activation setup:
• Max Load - If the load exceeds this value, the NOS system will be turned off. This is used for turbo
engines where the NOS system 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, in this case
the max load value should be set to 150kpa (ie the nitrous is always enabled). The max load value
is an absolute pressure value in kpa.
• Max RPM - If RPM exceeds this value the NOS output will be switched off.
• Min RPM - If the RPM is below this value the NOS system will not be activated.
• Min Throttle - The NOS system will be turned on above this value.
• Min Coolant Temp - The NOS system will not be activated unless the engine coolant temperature
is above this value.
• Min Time – Engine running time after which NOS can be activated.
• Ign. Retard - Amount of ignition retard when NOS is active.
• % Fuel Enrich - The percentage of fuel enrichment when NOS is activated. This is only a minor
