LED
The LED on the side of the unit will verify at power up by turning on for one second (the remote
indicator will also light up). It will also blink steady when the launch sequence is active (the Dark
Blue wire is connected to 12 volts). Once the car launches, the LED will turn off.
WIRING
VIOLET
On/Off. Connect to a switched 12 volt supply.
BLACK
Ground. Connect to battery negative or to engine ground.
BROWN
Indicator Alert. Connect to a 12 volt LED or bulb that will alert the user that the
launch sequence has been properly initiated by flashing. It will turn off when
the car is launched (12 volts removed from the Dark Blue).
GRAY
Tach input signal wire. Connect to the ignition tach output (12 volt square
wave).
CONTROL WIRES
DARK BLUE
Launch wire. This wire is activated when switched to 12 volts. At that point,
the first time point of the boost pressure curve is selected and the time is reset
to zero. This wire overrides the burnout wire (Light Blue) when both are active.
LIGHT BLUE
Burnout wire. This wire can be programmed to be active either with 12 volts,
or when connected to ground. When active, the Burnout boost pressure
value is activated, the acquisition record is stopped and armed for the launch.
ORANGE
Over-boost control wire. When connected to 12 volts, this will activate the
over-boost ramped pressure value.
WASTE GATE CONTROL WIRES
YELLOW
Provides a pulse width modulated ground to the waste gate solenoid valve.
Note that this wire is Normally Closed to Ground.
RED
Provides 12 volts to the waste gate electric air valve.
GREEN
Provides a pulse width modulated ground to the waste gate solenoid valve.
Note that this wire is Normally Open from ground.
These wires provide a self-protected driver with an output current load of up to 2 amps continuous.
RED
Provides 12 volts to the waste gate electric air valve.
MAP SENSOR
BROWN/WHITE Five volt supply wire.
BROWN
MAP output signal
3-pin connector goes to the external MAP or Gauge Pressure Sensor.
BROWN/
YELLOW
Ground
