SHIFT LIGHT
This program lets you select the number of gears (Last Gear), program the shift light to come on
when the holeshot 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.
