RPM Settings (Gauge Abbreviations)
1.
Mode (RPM Mode) -
Select how many pulses per rotation (ppr)
based on your tach signal source. When setting the Mode using the
gauge interface, you will also see a real-time display of the RPM to
ease the setup. Default is 1 pulse per rotation.
2.
Scale (RPM Scale) –
Select either 10230 or 20460 RPM scales.
Default is 10230
3.
Shift RPM –
Set to desired RPM to trigger illumination of the shift
light on the PSN-1. Default is 10230 RPM.
3.4
Nitrous Safety Settings (Gauge Abbreviations)
In an O2 error state, all relay functions are automatically
disabled.
1. Window Switch Min and Max RPM (Window Min and Max)
– This is
the engine RPM range where the PSN-1 will arm the system. When the
system is within the defined RPM window, “Armed” will be displayed on
the upper right hand corner viewport. To disable this function set the Min
RPM range to 0 RPM and maximum to 10230 RPM. Default setting is
Min RPM 2000 and Max RPM 4000.
2. Boost Cut by Bottle Pressure
(
Pressure Min)
- This is a safety trigger
to cut nitrous at a desired minimum bottle pressure. When the safety
Bottle Pressure is triggered, the PSN-1 will display “P Cut” on the upper
right hand corner viewport and the relay will interrupt all nitrous
functions. Default setting is 950 PSI.
3. Nitrous Cut by AFR
– This is a safety trigger to interrupt nitrous function
by a defined AFR. There are two setup parameters to trigger this safely
cut:
Min RPM (AFR RPM Min)
and
AFR Cut. Min RPM (AFR RPM Min)
is the minimum engine RPM where the safety cut will become active.
AFR Cut
is the defined lean A/F that will trigger the safety cut. When the
Nitrous Cut by AFR
is triggered, the PSN-1 will display “O2 Cut” on the
upper right hand corner and the relay will interrupt all Nitrous function.
Default setting is 2000 RPM at 13 AFR.
4. Valet ON/OFF –
When configured from the gauge, this setting is
accessed from the main screen. Press and HOLD both the left and right
interface buttons at the same time, this will disable/enable the Valet
function. When Valet mode is active, the relay will interrupt all solenoid
control and nitrous activation will not be possible. If there are no other
error codes on the status viewport of the screen, the PSN-1 will display
“Valet” when active. In LM Programmer, use the ‘Valet Mode OFF’
