BOOST RETARD CURVE
This timing curve can be programmed in relation to boost/vacuum pressure within the intake manifold.
The curve can be programmed from 2 psia-45 psia in 0.25 psia from 0°-25° in 0.1° increments. Up to
32 different points can be input on the Boost Chart. Also, all of these points are interpolated every
millisecond to create a smooth (no steps) curve. This curve can easily be edited using the Boost
Curve chart in the Pro-Data+ software. An MSD MAP sensor is required to use this feature and three
are offered:
1-Bar, for normally aspirated engines, PN 23111
2-Bar, for 2-30 psia, PN 23121
3-Bar, for 2-45 psia, PN 23131
Note: The Boost Retard Curve default is 0° retard.
Rev Average: This allows you to program the number of engine revolutions that occur to pro-
duce an average boost value. It is adjustable in 2, 4, 6 or 8 crankshaft revolutions. This function is
designed to help average the boost pressure to provide an accurate reading. The default is two
revolutions which should be ideal for the majority of applications.
PSI Sensor: This allows you to input the specification of the MAP sensor. Select a 15 psia, 30 psia
or 45 psia sensor. Default is 15 psia.
RUN RETARD CURVE
This program provides the ability to create a timing curve. The curve can be programmed from 0-12,500
rpm in 0.1° increments for every 100 rpm. You can program up to 32 different points on the map. Also,
all of these points are interpolated every millisecond to create a smooth (no steps) curve.
CYLINDER COUNT
CylCnt: This is the number of cylinders of the engine. Programmable for 4, 6 and 8-cylinders.
Once a change has been made, turn the ignition Off and On to reset.
HALL-EFFECT/ECU TRIGGER
The White/Blue wire can be used as the ignition trigger source with a Hall-effect distributor or ECU
trigger signal. Default is for Hall sensor. To use as an ECU trigger, ECU must be selected in the menu
(see page 14). Figure 4 and 5 show diagrams with the ECU trigger. Note that a distributor is still re-
quired.
ALERTS
This is only used with the Hand Held Monitor, PN 7550. You can program an alert to interrupt the screen
on the monitor. You can select which alerts to show and how often. The alert is for Low Battery.
Fault: Program the number of counts that occur for a Low Voltage alert.
BrownOut 0: This is the count of low voltage resets. This should always be set at 0.
WatchDog: The count of Watch Dog resets. This should always be set at 0.
TEST
Can be set to spark On for normal operation. Set to spark Off to disable the output as an antitheft
setting.
