Overview
The launch control module can control the engine RPM by monitoring and modifying the
ignition pulses to the coil(s).
It has two modes of operation:
1. Normal mode:
The engine runs normally without any change as if the launch control is not there
2. Launch activated mode:
In this mode a rev-limit is set beyond which the launch control will apply modification to the
spark delay and miss some spark events to keep the revs under the specified limit.
The modes can be changed by pressing the clutch when the second mode is activated. For
the unit to operate as rev limiter all the time, the wire going to the clutch switch can be
permanently connected to ground to keep the module in mode 2.
Features
By keeping the engine within suitable RPM when the clutch is pressed, best launching can
be achieved, reducing wheel spin. Flat-shift is another enhancement that allows to do gear
shifts while keeping the throttle pedal completely pressed. This REMOVES lag when shifting
in turbocharged vehicles and reduces shifting time.
Besides, by tweaking the “Miss” and “Delay” settings the sound and “feel” of the rev limiter
can be varied widely. Hint: big “Delay” setting will make very loud sound from the exhaust
and produce flames.
