Programmable Capacitive Discharge Ignition Control

Fits Race Engines Using a Magnetic Pickup or Points Trigger

Three Programmable Rev Limits in 100 RPM Increments

Launch Limit Adjustable from 2,000 to 12,500 RPM

Individual Cylinder Timing

Bracket and heads-up racers need timing and rev control that can be dialed in for each run rather than set once and left alone. This capacitive discharge ignition is programmed from a PC, holding timing accuracy to better than a tenth of a degree while managing separate burnout, launch and overrev limits, three cumulative step retards, and per-cylinder timing when a cam sync sensor is fitted.

MSD 7530T Programmable Digital-7 Ignition Control Features:

Capacitive discharge design charges to 520-535 volts so full coil energy is available even at high rpm.
High speed RISC microcontroller maintains timing accuracy to better than 0.1 degree and plus or minus 2 rpm.
Three programmable rev limits in 100 rpm increments: burnout, launch and max speed, with the launch limit taking priority.
Launch rev limit adjustable from 2,000 to 12,500 rpm.
Three step retards are cumulative to a maximum of 30 degrees.
Start retard adjustable from 0 to 25 degrees, active below 500 rpm and off above 800 rpm.
Launch retard ramp programmable from 0 to 15 degrees over 0 to 2.5 seconds.
Timed safety rev limit ramps the engine down for a safe shutdown.
Individual cylinder timing when used with a cam sync sensor.
Traction Control Detection circuit monitors the magnetic pickup for signal tampering.
Reverse polarity protection and an LED that flashes diagnostic trouble codes.
Multiple spark series lasts 21 degrees of crankshaft rotation, becoming a single spark above 3,300 rpm.

No Timing Compromises

Ignition timing is always a compromise between cylinders. The dynamics of air and fuel flow into each cylinder is never exactly the same no matter how much machining magic has been done. This has always caused top engine builders to compromise their ignition timing. With the Programmable 7-Series Race Ignition Boxes advanced Individual Cylinder Management system and other exact timing programs, you will never need to compromise again.

When you need race-proven ignition performance that won’t let you down, the MSD 7-Series Race Ignition Boxes are built to deliver. Engineered for serious competitors, these ignition systems offer unmatched spark energy, advanced features, and rugged construction to handle the harshest racing conditions.

The MSD Digital 7 ignition box delivers ultra-fast processing power and precision timing control, making it the ideal choice for high-horsepower drag, circle track, and off-road applications. With programmable RPM limits, timing curves, and data acquisition capabilities, this unit gives racers the ultimate edge in tuning and customization.

For those looking for legendary performance in a straightforward design, the MSD 7AL-2 remains a favorite in the racing community. It’s known for delivering a powerful capacitive discharge spark throughout the RPM range while providing built-in rev control and compatibility with MSD’s RPM modules for quick adjustments at the track.

The MSD 7-Series line stands apart with its durability, consistent output, and seamless integration with other MSD components. Whether you're pushing big boost, nitrous, or high compression, these ignition boxes provide the spark intensity and reliability needed to keep your engine firing strong—pass after pass.

Built for racers who demand precision and power, the MSD 7-Series Race Ignition Boxes are the backbone of countless winning setups. Trust MSD to ignite your competitive edge and help you dominate the race day.
