MSD Performance 6520 - Digital 6-Plus Ignition Control Box. Start & Stage retard
The MSD Digital-6 Plus Ignition Control combines terrific power, digital accuracy, and great accessories making it ideal for street/strip applications. Every spark of the Digital-6 Plus Ignition is packed with 135 millijoules of spark energy and 535 primary volts. For nitrous-equipped cars, the Digital-6 Plus offers a step retard that will retard the timing when the nitrous is activated. There is also a 2-step rev limiter for holeshot consistency and overrev protection. The Digital-6 Plus accepts points, amplifier, and mag pickup inputs and will run on 4, 6, or 8 cylinder engines. The MSD Digital 6 Plus uses a high-speed RISC microcontroller to control the ignition's output while constantly analyzing the various inputs such as supply voltage, trigger signals, and rpm. The high-speed controller can make extremely quick compensations to the output voltage, multiple spark series, timing, and rpm limits while maintaining accurate timing signals to within 1° and 1% of the rpm limits. The circuits and controller of the Digital 6 Plus have been thoroughly debounced and isolated to create protection against Electro-Magnetic Interference (EMI).
 
  • Switch between two rev limits that adjust with rotary switches in 100 rpm increments.
  • Single stage retard for nitrous and top-end performance.
  • Start retard eases pressure on the starter, flywheel and engine.
  • Adjustable magnetic pickup compensation produces accurate trigger signals.
  • LED display warns of trigger signal problems or faulty charging system.

MSD Performance

MSD Performance is one of the most recognized brands in high-performance ignition systems. The name MSD stands for Multiple Spark Discharge, a technology developed to provide strong and consistent ignition performance. MSD products are widely used in classic American cars, muscle cars, street-performance vehicles and racing applications. The MSD range includes ignition control boxes, performance coils, distributors, spark plug wires, crank triggers, starters, RPM controls and electrical components. Popular products such as the MSD 6-series ignition controls and Blaster coils are used in a wide variety of performance builds. MSD also offers different distributor designs, including Pro-Billet and Ready-to-Run distributors. Ready-to-Run models contain their own ignition module, while Pro-Billet distributors can be combined with external MSD ignition controls for more advanced performance setups. Whether you are upgrading a classic V8, improving ignition reliability or building a dedicated race engine, MSD provides proven ignition components designed to deliver accurate timing, strong spark energy and consistent engine performance.
