The retard Rate setting controls how quickly the controller goes to the amount of timing retard set with
the Degrees switch. For example, if you have the Degrees switch set to 10 degrees and you have the
Rate switch set to 1 second, after 0.5 seconds you will have roughly 5 degrees of retard and it will take
one second to build up to the full 10 degrees of retard.
When using the MAP sensor input, the Rate setting controls how many degrees of retard per pound (psi)
of boost and the Degrees setting controls the maximum number of degrees retard to allow. For example,
if you have the controller set to 10 degrees with the Degrees switch (position A) and the Rate switch set
to 3 degrees per pound of boost (position F), then at 1 psi of boost you would have 3 degrees of retard,
at 2 psi of boost you would have 6 degrees of retard, at 3 psi you would have 9 degrees of retard but at
4 psi you would only have 10 degrees of retard because you have the maximum setting with the Degree
switch set to 10. If you had the Degrees switch set to 15 degrees (position F) then at 4 psi of boost you
would have 12 degrees of retard.
When using boost based timing retard the orange retard activation input wire will force the retard to the
maximum retard level setting on the Degrees switch no matter what the boost level is. This allows you
to use the orange trigger wire to retard timing at the line in order to build boost and then still use the
boost based timing retard as you go down the track.
Timing retard notes:
• When the LNC-002 is powered up with no MAP Sensor installed it will default to Time Based
Retard mode.
• When the LNC-002 is powered up with a MAP Sensor installed it will switch to Boost Retard mode.
The “Degrees” switch will still set the Maximum amount of retard allowed. The “Rate” switch will
control the degrees of retard applied for each lb of boost applied to the MAP Sensor.
Timing retard analog output
The LNC-002 provides an analog voltage output that indicates the amount of timing retard that is being
applied. The gray analog output wire provides a linear 0 to 3 volt DC output with 0 volts indicating
0 degrees of timing retard and 3 volts indicating 15 degrees of timing retard. This voltage value can
be logged with EFILive, HPTuners, DashDAQ or other devices to allow you to determine how much
timing you really had while going down the track.
Note - because the LNC-002 modifies the ignition timing after the PCM or ECM, the factory computer
is not aware of the changed timing so it will not display the modified timing value in a scan tool.
