MSD 7531 Ignition Control Module

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!
