Torque reduction activation:
• How you plan to activate and control the
torque reduction events will dictate how you
wire the activation/control wires.
• If you want to use a momentary switch to
activate the torque reduction event (timing
retard) and then have the dials on the LNC-
TRM control how much timing is removed and
for how long then all you need to do is wire
a momentary switch to the yellow (+12 volt
activation) or green (ground activation) input.
If you don’t have a ground source or +12 volt
source you want to use you can also wire the
momentary switch in between the yellow and
green wires. Then you set the switches for the Retard Slope, Maximum Retard and Kill Time you
want to occur each time you activate the input.
• If you want to manually control how long the timing retard event lasts but allow the switches on
the LNC-TRM to control the amount of timing retard then you would wire in a switch to the green
or yellow wire as above but then you would set the “Kill Time” switch to position “F”. The timing
retard will then be active for as long as you have the switch active (connected to ground or +12 volt
depending on how you have it wired).
• This would also be how you would wire the LNC-TRM if you wanted an external device to
control it via a simple switched output. An example would be a timer output from a time delay
box or a nitrous controller.
• If you want an external device to control when the timing retard becomes active and how much
timing is taken out then do not connect anything to either of the digital inputs (green or yellow
wire). Connect the 0-5 Volt output from the device that is going to control the timing to the purple
input wire on the LNC-TRM. We also recommend connecting the black ground wire to the ground
signal of the external device so that the two modules are using a common ground (to reduce the
changes of a voltage offset between the two devices).
• Examples of what might be connected to this input would be:
• External traction control devices like the Davis Technologies modules (see wiring diagrams
on pages 17 and 18)
• LPE NCC-002 nitrous controller when performing progressive timing retard (see page 16)
• Transmission controller performing a torque cut during a gear change event
