HAND HELD PROGRAMMER, PN 7550

The Hand Held Programmer (Fig. 1) allows you to select and program the

different features of the Programmable Midget Ignition. The Ignition does

not need to be connected to the programmer in order to operate because

the program values are stored in an erasable memory circuit in the Ignition

Control. The Programmer only needs to be connected when you want to

check or change programs or to monitor different operating parameters.

PRO-DATA+ (INCLUDED)

MSD has a software package for your PC that allows you to create timing and rpm programs

for this ignition. All of the adjustable parameters can be reviewed and set, then uploaded to

the ignition. This software program is included to allow the upload and download of programs

for the Ignition Control as well as monitoring and editing of all the ignition's parameters. It will

work with any PC running Windows 95, 98, NT, ME, 2000 or XP. More information is available

in the Programming instructions. Visit our website to download the current version at www.

msdignition.com.

CYLINDER SELECTION

The Ignition default is for 4-cylinder operation only, using two mag pickups and two Ignition

Coils for waste spark operation.

PROGRAMMING FEATURES

The most current release of the

MSD Pro-Data+ software is available which allows trans-

ferring all of the menu items and user data to the PC or from the PC to the timing controller

as well as viewing the Alternate and Run Timing curves and the monitored items. Also this

program allows editing the Alternate and Run timing curves on the PC. This software allows all

the data to be printed out, timing plots and the other data items, from the Graph-View program.

RUN TIMING RETARD CURVE

This is the default timing curve and is active at all times unless the Alternate Timing Curve

is activated. This Curve is adjustable from 800 – 15,000 rpm and is programmable in 0.1°

increments every 100 rpm. The maximum amount of retard is 25°.

ALTERNATE TIMING RETARD CURVE

This feature provides the opportunity to switch to a second timing curve. This Curve will

override the Run Timing curve when the Dark Blue wire is supplied with 12 volts. It will remain

active until the 12 volts are removed (where the Run Curve becomes active again). This Curve

is adjustable from 800 – 15,000 rpm and is programmable in 0.1° increments every 100 rpm.

The maximum amount of retard is 25°.

Note: Both the Run Timing Curve and the Alternate Timing Curve defaults are zero degrees

of retard over the full RPM range.

START RETARD

This program will retard the timing when cranking to ease the load on the starter and fly-

wheel. The retard will activate during cranking and will automatically turn off at 800 rpm. If

the engine drops below 500 rpm, the Start Retard rate will reactivate. The Start Retard has a

default setting of 15°.
