RPM/TIME/PRESSURE ACTIVATION SWITCH
This program lets you activate a circuit by supplying a ground path on the Brown/White wire (up to 3
Amps continuous). This can be activated in one of several ways: RPM, Time or Pressure.
RPM Window: Program an rpm value to activate and deactivate a circuit from 800 – 12,500
rpm in 100 rpm increments.
RPM On: Rpm that the circuit is activated
RPM Off: Rpm that the circuit is deactivated
RPM/Pressure Hysterisis: Built in Hysterisis allows the deactivation point to be set lower
than the activation value.
Pressure Activation: Program a manifold pressure activation point from 2 – 45 psia in 0.25 psi incre-
ments. This also can be programmed where the deactivation point is less than the activation point.
PSI Switch On: The pressure at which a circuit can be activated through the Brown /White
wire. Adjustable from 0-45psi.
PSI Switch Off: The pressure at which the circuit is deactivated. Adjustable from 0-45psi.This
can be set lower than the activation pressure.
PSI Delay: Delay the activation or deactivation of the pressure switch.
OffDly: The amount of time that the switch delays turning off after the given pressure is reached.
Adjusted from 0-25 seconds.
OnDly: The amount of time that the switch delays turning on after the given pressure is reached.
Adjusted from 0-25 seconds.
Time Based: Program an activation point in 0.1 second increments after the launch. Up to 25 sec-
onds of total time.
OnDelay: The amount of time after launch (12 volts removed from the Dark Blue wire).
OffDelay: The amount of time that the switch stays activated. This can be programmed
from 0-25 seconds. It will always deactivate after 25 seconds.
SHIFT LIGHT
This program lets you select the number of gears (Last Gear), program the shift light to come on when
the Launch Light rpm is reached, set an rpm point for each gear and the rpm drop for the ignition
to recognize as a gear shift between each gear. When the correct rpm is reached the Yellow wire is
switched to ground to turn the shift light on.
Launch Light: This programs an rpm window that will illuminate the shift light when the correct rpm
is reached for the holeshot. When the rpm is in this window the light will be on solid. If the rpm goes
high, the light will flash. If the rpm goes low, the light turns off.
RpmHi: The high rpm for the launch light program.
RpmLo: The low rpm for the launch light program.
ShiftLight: Program the rpm point for each gear change.
(1)Rpm
First gear rpm point to shift.
(2)Rpm
Second gear rpm point to shift.
(3-5 gears)
ShiftGear: Program the rpm drop between each gear that the ignition must see to recognize
a shift. Programmable from 200-1500 rpm.
(1)DropRpm
Rpm drop between first and second.
(2)DropRpm
Rpm drop between second and third.
(3-5 gears)
LastGear: The program lets you select the number of gears to use with the shift light from
2-6 gears. Default is five gears.
