Present
– “click” box if using stage 1
Pause Enabled
– “click” box for pause enabled. If selected, when nitrous is activated, and the driver has to lift off the throttle
causing the system
to deactivate momentarily, and then gets back on the throttle, the system will resume the “ramp” in the same
spot when it was deactivated. If this is not enabled, the nitrous/fuel ramp will start at the beginning if this occurs.
First Gear Lockout
– This is a method that can allow for the system to not be engaged in low gear. It operates only when the
driver hits the RPM Nitrous Cutoff point. After this occurs, the system will activate as programmed. If the RPM Nitrous Cutoff
point is not hit at all, the system will not turn on. As an example, set the nitrous RPM cutoff point to 6800 RPM. The driver needs
to shift at 6900+ RPM in low gear. When the 1-2 gear change is made, the system will then activate as programmed from that
point on. In other words the controller must see 6800 RPM 1 time before it will activate the system.
Input #1 Will
– Select “Be Ignored By”, “Enable”, or “Disable” for this stage for Input #1
Input #2 Will -
Select “Be Ignored By”, “Enable”, or “Disable” for this stage for Input #2
Strategy Type
– Select from “Time Based”, “RPM Based”, “MAP Based”, or “Purge”.
o
Time Based
– Allows user to program nitrous/fuel percentage vs. time
o
RPM Based
– Allows user to program nitrous/fuel percentage vs. engine RPM
o
MAP Based
– Allows user to program nitrous/fuel percentage vs engine manifold pressure. This would typically be used
with a turbocharged application. This can be used to spool the turbo on the starting line.
o
Purge
– Allows user to program as a “progressive purge” function
Map Nitrous Cutoff
– Automatically shuts the system off at a programmed boost pressure.
Set to “20” if not using
.
NOTE: MAKE SURE THIS IS SET TO 20, if set to 0, the system may deactivate at WOT as it will sense 0 as atmospheric, WOT
pressure!! 20 is n
ot a “special” number, just a higher number so it won’t deactivate due to atmospheric pressure. If truly
using for a boost shutoff, enter the intended number.
RPM Nitrous Cutoff
– Automatically shuts the system off at a programmed RPM. Same function as the upper limit of a window
switch.
Start % - Allows for the start percentage to be typed in.
Final % - Allows for the end percentage to be typed in.
Frequency
– Frequency the solenoids will be pulsed at. 15-22 Hz is the typical range. NOS recommends 20 Hz for their
solenoids.
RPM Trigger
– RPM at which the system will activate at. Same as the lower limit on a window switch.
Delay
– (Time based only) Time delay that can be added after system is triggered for activation. This is used for fine tuning or
delayed activation of a second stage when the same input is used.
Ramp Time - (Time based only) Ramp time from activation to final %
RPM End
– (RPM based only) End RPM for final nitrous/fuel %. At RPM higher than this, % stays the same.
MAP Trigger - (MAP based only) Manifold Pressure that activates ramp.
MAP End - (MAP based only) End Manifold pressure for final nitrous/fuel %. At RPM higher than this, % stays the same.
Graph Features
“Reset to Straight Line” – Will create a linear, straight line between the Start % and Final %
“Smooth Points” – Each time this is hit, it performs a smoothing function to the curve.
“Undo” – Undoes the last smoothing function
“Smooth When Dragging” – Will “pull” and smooth surrounding points when modifying the curve.
