Stage2 Tab—Setup
Enable Stage2—this seng allows the enre Stage2 system to be turned off/on as desired.
Important—when Stage is off the Stage2 Timer output will be disabled as well as any Stage2 sengs for Timer1 Output and the Relay
output.
Stage2 Delay Timer ‐ this seng sets the delay me in seconds
before Stage2 starts aer Acvaon.
Valid range ‐ 0.000 to 10.000 in .001 second increments.
Enable Stage2 RPM control ‐ this seng enables a RPM Window funcon for Stage2.
Note—If the RPM window feature is enabled and the engine is
not running the solenoids can be dry fired for tesng. Once an
RPM signal is present the solenoids will only operate at the
desired RPM range.
Stage2 Minimum RPM ‐ this seng controls the minimum engine RPM that must be achieved before Stage2 will turn On. A seng of
0 will disable the Minimum RPM funcon and the Maximum RPM seng will be used to turn off Stage2 if the engine RPM exceeds the
seng.
Valid range ‐ 0 to 15,900 RPM in 10 RPM Increments.
Stage2 Maximum RPM ‐ this seng controls the maximum engine RPM that Stage2 remains On. When the engine RPM exceeds this
seng Stage2 will be turned Off. The Maximum RPM must be at least 100 RPM greater than the Minimum RPM seng.
Valid range ‐ 1000 to 16,000 RPM in 10 RPM increments.
Stage2 Synchronize Pulse Frequency ‐ the Stage2 nitrous and fuel solenoids can be configured to funcon 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 opon 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 different frequencies (hertz) you MUST insure that both sole‐
noids operate as desired in the delivery of nitrous and fuel to the engine!
Informaon ‐ the solenoid pulse frequency (hertz) is how many mes per second the solenoids open and close when not at 0 or 100
percent operaon. 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 different styles of solenoids available and they will react differently to changes in the operang frequency. It is up to
the user to verify that the solenoids are opening properly with the sengs used for operaon
As a general rule a lower frequency seng will allow a solenoid to open properly when a high nitrous pressure is used and a low
starng percentage. This is just a general rule, test your sengs!
