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.
