Launch Control/2-Step Features
The independent coil drive of the LNC-002 provides sequential ignition kill when RPM limiting is
active. The desired RPM limiting is set as shown on page 3. The activation for the Launch Control/2-
Step function is controlled by the ground (green) or +12 volt (yellow) activation wires.
If you are triggering off of the clutch switch, the 2-step will trigger each time you depress the clutch
pedal. This can be used to provide an ignition cut/torque cut on each gear change to potentially allow
for faster shifts/faster clutch engagement.
If you do not want the 2-step to trigger when you engage the clutch pedal once you are moving then you
will need to install a momentary switch or use the Lingenfelter MPH activated switch. With the MPH
activated switch you can set at what MPH you want the 2-Step activation to be disabled.
Timing Retard Features
Up to 15 degrees of timing retard can be applied. The amount of retard is adjusted with the Degrees
switch and the retard rate is adjusted with the Rate switch. The timing retard function can be triggered
two ways:
• Retard activation wire - orange wire to be connected to a 12 volt DC activation trigger switch
• MAP sensor input connection - to be connected to a GM 3 bar MAP sensor
For either trigger method, ignition retard is only active when the engine RPM is above 1,000 RPM.
MAP sensor based retard is only active if a MAP sensor is connected to the MAP sensor input. If
the orange wire is connected while a MAP sensor is also connected then the timing retard will go to
the maximum retard value set with the Degrees switch. The Retard may be activated while the RPM
Limiter is active.
Setting The Spark Timing Retard Value
The spark retard amount is set with the Degrees switch on the box. The settings are as followings:
