PROGRAMMABLE FEATURES
The following explains the programmable features of the PN 6012 Controller. The features are listed
in the same order shown on the Data Editor list in the software. Note that the Help pull down menu
of the software offers explanations of all the features.
Note: STATS Stat 1 or SCAN are display features only used with the Hand Held Monitors, PN
7550, PN 7553.
RPM TABLE (RPMtbl)
Note: When plotting a timing curve by using the RPM Table or MAP Table through your PC, there must
NOT be a Timing Module installed. Power-up with a module installed will override the saved
timing plot.
This setting can only be modified from the RPM Timing Curve edit graph on the lower right of the
screen. It can also be set with the Hand Held Monitor. The chart allows you to map out an entire timing
curve, much like the centrifugal advance of a mechanical distributor.
To create a map, simply position the mouse at a point on the chart and right click to add a dot. By
moving the mouse over this point and a left click, the dot changes to red (active) and you can move
it around the map.
Note: The timing has minimum and maximum limits that are set in the Data Editor Menu. These
settings include the cumulative value of any vacuum advance or retard as well as the Step
Retard if used.
MAP TABLE (MAPtbl)
Note: In order to take advantage of a vacuum advance or retard, a MAP sensor is required.
Note: When plotting a timing curve by using the RPM Table or MAP Table through your PC, there must
NOT be a Timing Module installed. Power-up with a module installed will override the saved
timing plot.
This is a Manifold Absolute Pressure (MAP) chart. It gives you the capability of modifying the timing
curve based on manifold pressure (vacuum or boost). A curve can be created from the MAP Advance
Curve graph on the upper right of the screen. It can also be set with the Hand Held Monitor. The chart
allows you to map out an advance curve based on manifold vacuum (much like the vacuum advance
on a mechanical distributor).
To create a map, simply position the mouse at a point on the chart and right click to add a dot. By moving the
mouse over this point and a left click, the dot changes to red (active) and you can move it around the map.
Note: The timing has minimum and maximum limits that are set in the Data Editor Menu. These
settings include the cumulative value of any vacuum advance or retard as well as the Step
Retard if activated.
MAP SENSOR SELECT
Allows the selection of a 2, 3, or 4-bar MAP sensor. This setting should be set to match the MAP
Sensor in use: 2-bar (2-20 psia), 3-bar (2-30 psia) or 4-bar (2-45 psia). GM Part Numbers 12615136
and 12580698 are 2-bar sensors that connect to the MSD harness.
TIMING LIMIT
There are two adjustments that set the limits of ignition timing. These settings are meant as safety
targets to keep the timing in check. Both the Minimum and Max values include any timing retards or
advancements.
Min Timing This is minimum amount of timing advance. It is adjustable from 0°-20° BTDC
with a default of 5°.
Max Timing This is the maximum amount of timing advance. It is adjustable from 25°-65°
BTDC with a default of 45°.
