Used - (7531) MSD Programmable Digital-7 Plus

This is a perfectly operating MSD Digital-7 Plus that was used in an old build of ours, but we have decided to update to a newer combination. This comes with the wiring pictured. 

Features:

• Map a complete timing curve for every gear.

• Output to activate a device through rpm, time or pressure inputs.

• Automatic magnetic pickup compensation for crank triggers or distributor pick-ups.

• Program your engine's firing order for ease of setting the cylinder-to-cylinder timing.

• There is a cam sync output for fuel controllers or data acquisition.

• Vacuum advance and boost retard is selectable through a MAP sensor.

• Program an rpm limit that is ramped in during the launch.

• Select the rpm limiter value in rpm/seconds.

• Acquire 20 seconds of run data including two seconds prior to launch.

• View all ignition events in a new Launch History window including the retard sum, manifold pressure, rpm, shift points and more.

• Updated X-Y plots with interpolation for smooth changes.

• Stage retards can be set to ramp the timing.

• An upgraded micro- controller runs at 40MHz enabling timing accuracy within 0.1 degrees and +/-1 rpm at up to 10,000 rpm!
