Progressive Nitrous Timing Retard

To allow a nitrous or other external device to control the amount of timing retard and when it

occurs:

• Set the LNC-TRM to the desired Retard Slope using switch #1

• Set the LNC-TRM to the desired Maximum Retard using switch #2

• Connect the analog output from your external device to the purple analog input wire on the

LNC-TRM

• This allows the nitrous or other external controller to control the amount of timing retard

while still allowing the LNC-TRM to limit the timing retard to the user set Max Retard

setting.

NOTE - with the analog input voltage going to the purple input wire, the yellow and the

green activation inputs are ignored and the Kill Time and the Kill Time Adder are also

ignored when ever a voltage of above 0.5 volts is sent to that input.
