MSD Digital-7 Plus Programmable Ignition Control - 7531

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. 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 plus software on a mini CD.
