MSD Digital 7-Plus Programmable Ignition Control Microprocessor

Riding the dots! This one set the standard for programmable ignition control. If you’re a consummate engine tuner and know how to take advantage of minute changes in timing during a quarter-mile pass, then the Programmable Digital-7 Plus is the ignition for you! All of the standard programmable features such as Individual Cylinder Management, Step Retards, Rev Limits, Shift Points, and more are included in the Plus version but you also get more. Much, much more.

A MAP sensor is required for the boost circuit. The Ignition is supplied with wiring harnesses, mounting hardware, an RS232 computer harness, and the Pro-Data+ software on a mini-CD.

Note: Illegal for use in NHRA classes except Pro Mod. The Programmable-7 Series of ignition controls has been updated with the Power Grid Ignition System.
