Programmable Digital-7 Plus Ignition
The Programmable Digital-7 Plus Ignition includes all of the standard programmable features such as Individual Cylinder Management, Step Retards, Rev Limits, and Shift Points.
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
