SEQUENCE OF EVENTS
The sequence of the Boost Controller is controlled through the Burnout wire (Light Blue) and the
Launch Wire (Dark Blue). The Light Blue wire must be activated to arm the acquisition feature of
the controller followed by the activation of the Dark Blue wire (which overrides the Burnout setting).
When the 12 volts is removed from the Dark Blue wire the acquisition begins (with two seconds
prior) as does the boost map that you plotted.
It is recommended to connect the Light Blue wire to the brake switch and the Dark Blue to the trans
brake or clutch switch. As the car rolls into the lights, the Light Blue wire will be activated through
the brake switch to arm the acquisition. Once in, the trans brake is activated along with the Dark
Blue Launch wire which puts the Controller at zero time or the first value in the Launch boost curve
to control the boost pressure. When the transbrake is then released, the launch wire is deactivated
and the sequence begins.
Note:The Light Blue wire MUST be deactivated before the Dark Blue wire is deactivated in order to
set a proper launch and record sequence.
