Pro-Data+ Software

The Pro-Data+ software is a Windows based, easy to use software. It opens quickly and displays a

plotted rpm/timing chart for the entire run and for the launch. There is also a tachometer and dial

showing the timing retard plus a complete ladder of all of the adjustments. The software can be used

with any PC running Windows 95, 98 or NT. It is available on a 3.5 floppy or can be downloaded

If you do not have a laptop or PC, all of the Programmable 7 Ignition Control’s optional programs

can be set with this hand held Programmer/Monitor. The Programmer communicates to the Pro-

grammable Ignition via the 9-pin cable. The LCD will display the programming options which you

can scroll through to adjust or view the program that is already in the ignition.

This handy controller lets you change the launch rpm setting of the Programmable 7 Ignition Control

manually and at the last minute. It plugs into the 9-pin harness. There are two control knobs and the

launch setting can be adjusted from 3,000 to 12,500 rpm in 100 rpm increments. The rpm limit can be

changed with the engine running and the new setting is verified with the flash of a built-in LED.

ynchronization Pickup Kit

In order to take advantage of the Programmable Digital-7’s Individual Cylinder Management

system, a synchronization pickup must be incorporated so the ignition knows exactly which cylin-

der is firing. With this information the MSD can begin your unique timing sequence through each

cylinder! MSD offers two ways to accomplish this.

This pickup simply installs to the number one spark plug wire and senses the trigger signal. A

fiber optic cable connects to the ignition to send the signal.
