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
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.
Features:
- Automatic magnetic pickup compensation for crank triggers or distributor pick- ups.
- Vacuum advance and boost retard is selectable through a MAP sensor.
- There is a cam sync output for fuel controllers or data acquisition.
- 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.
- Program your engine's firing order for ease of setting the cylinder-to-cylinder timing.
- Output to activate a device through rpm, time or pressure inputs.
- Program an rpm limit that is ramped in during the launch.
- Stage retards can be set to ramp the timing.
- Acquire 20 seconds of run data including two seconds prior to launch.
- An upgraded micro- controller runs at 40MHz enabling timing accuracy within 0.1 degrees and +/-1 rpm at up to 10,000 rpm!
- Select the rpm limiter value in rpm/seconds.
- 1.1 Amp per 1,000 RPM
- Map a complete timing curve for every gear.
