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.
Programmable Digital-7 Plus 
Features
- Map a complete timing curve for every gear.
- Stage retards can be set to ramp the timing.
- Updated X-Y plots with interpolation for smooth changes.
- View all ignition events in a new Launch History window including the retard sum, manifold pressure, rpm, shift points and more.
- Acquire 20 seconds of run data including two seconds prior to launch.

Ignitions
Since electricity is not something we can physically see, the ignition system of our cars sometimes holds a little mystery or suspicion in its operation. It's important to realize that electricity, especially in an automotive setting, is not magic. And it's also important to realize that the ignition is key to your engine's performance. Your engine's overall performance is counting on that spark for complete combustion. Once you have a better understanding on how the ignition works and what each component actually does, things will begin to all make sense – and you'll be able to build the right ignition for your engine. Key goals of the ignition system:
- Produce and deliver a high-voltage spark from a low voltage supply source (the battery)
- This spark must be distributed to each combustion chamber as the piston nears top dead center on the compression stroke of the piston
- Control and even alter when the spark occurs in the cylinder to meet different engine demands
- Deliver a spark that has enough voltage and energy to ensure combustion of the fuel mixture
- Be able to reliably accomplish these goals throughout a variety of rpm, load
