Stage2 Tab—Setup
Enable Stage2—
this se ng allows the en re Stage2 system to be turned o
ff
/on as desired.
Important—
when Stage is o
ff
the Stage2 Timer output will be disabled as well as any Stage2 se ngs for Timer1 Output and the Relay
output.
Stage2 Delay Timer
‐
this se ng sets the delay me in seconds
before Stage2 starts a er Ac va on.
Valid range
‐
0.000 to 10.000 in .001 second increments.
Enable Stage2 RPM control
‐
this se ng enables a RPM Window func on for Stage2.
Note—If the RPM window feature is enabled and the engine is
not running the solenoids can be dry
fi
red for tes ng. Once an
RPM signal is present the solenoids will only operate at the
desired RPM range.
Stage2 Minimum RPM
‐
this se ng controls the minimum engine RPM that must be achieved before Stage2 will turn On. A se ng of
0 will disable the Minimum RPM func on and the Maximum RPM se ng will be used to turn o
ff
Stage2 if the engine RPM exceeds the
se ng.
Valid range
‐
0 to 15,900 RPM in 10 RPM Increments.
Stage2 Maximum RPM
‐
this se ng controls the maximum engine RPM that Stage2 remains On. When the engine RPM exceeds this
se ng Stage2 will be turned O
ff
. The Maximum RPM must be at least 100 RPM greater than the Minimum RPM se ng.
Valid range
‐
1000 to 16,000 RPM in 10 RPM increments.
Stage2 Synchronize Pulse Frequency
‐
the Stage2 nitrous and fuel solenoids can be con
fi
gured to func on at the nitrous sole
‐
noid frequency (hertz) only (both Stage2 outputs synchronized). Or the Stage2 nitrous and fuel solenoid output frequencies (hertz)
may be set independently.
Note—this op on is only available if the
All Solenoids use Stage1 Nitrous pulse frequency
is enabled in the Stage1 Setup.
IMPORTANT
‐
if you choose to operate the nitrous and fuel solenoids at di
ff
erent frequencies (hertz) you MUST insure that both sole
‐
noids operate as desired in the delivery of nitrous and fuel to the engine!
Informa on
‐
the solenoid pulse frequency (hertz) is how many mes per second the solenoids open and close when not at 0 or 100
percent opera on. Example
‐
pulse frequency set to 10 hertz and 50 percent, the solenoids would open and close 10 mes per sec
‐
ond. Total me for each pulse = 1 / 10 = .1 second, total me solenoid would be on = .1 * .50% = .05 second.
There are many di
ff
erent styles of solenoids available and they will react di
ff
erently to changes in the opera ng frequency. It is up to
the user to verify that the solenoids are opening properly with the se ngs used for opera on
As a general rule a lower frequency se ng will allow a solenoid to open properly when a high nitrous pressure is used and a low
star ng percentage. This is just a general rule, test your se ngs!
