Burnout Rev Limit. When 12 volts are applied the Burnout Rev Limit is

active.This disables the Slew Rate rev limits and overrides other rev limits.

It is recommended to have this wire switched from an outside source, such

as the crew chief before the burnout and while staging the car.

LAUNCH

This wire activates the Launch Rev Limit and is the main reset wire for

several features of the Ignition. When 12 volts are applied to this wire it

will activate the Launch Rev Limit. It also resets the shift light, the gear

indicator to first gear, the Launch Retard curve and select Gear 1 curve.

When 12 volts is removed, the Launch Time begins as does the Gear 1

curve. When 12 volts are applied the Slew Rate Rev limit will be disabled

as well as the Time-Based Rev Limit curve.
