MSD Ignition 7531 Digital-7 Plus Programmable Ignition Control Features:
- ICM Timing Control: Adjust ignition timing up to 5 degrees of retard into each cylinder in 0.1-degree increments
- Run Curve: Plot a timing curve of 0.1 degrees per 100 RPMs throughout the entire rpm range
- Launch Curve: Program a timing curve exclusively for the launch
- Launch Retard: Retard the timing up to 15 degrees for 0-2.5 seconds after launch
- Step Retards: Three steps of retard that can be activated with nitrous solenoids or switches
- Gear Retards: Program a timing retard up to 5 degrees for every gear change
- Start Retard: Ease engine cranking with an adjustable retard during start-up
- Three-Step Rev Control: Program rev limits in 100 rpm increments for burnout, launch and overrev protection
- Shift Light: Program a different rpm setting for each gear change for up to six gears
- RPM Activated Window Switch: Activate a circuit at an adjustable rpm such as a nitrous solenoid, then set another rpm level to deactivate the same circuit
- 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
- Select the RPM limiter value in RPM/Seconds
- Vacuum advance and boost retard is selectable through a MAP sensor
- There is a cam sync output for fuel controllers or data acquisition
- Program your engine's firing order for ease of setting the cylinder-to-cylinder timing
- Automatic magnetic pickup compensation for crank triggers or distributor pickups
- Output to activate a device through RPM, time or pressure inputs
- An upgraded microcontroller runs at 40mHz enabling timing accuracy within 0.1 degrees and +/- RPM at up to 10000 RPM

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
Electrical Cords
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
