MSD Digital-6 Plus Ignition Controller 6520

MSD's Digital-6 Plus ignition controller combines terrific power, digital accuracy and great accessories making it ideal for street/strip applications, with every spark from the Digital-6 Plus Ignition unit, 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 over-rev protection.

The Digital-6 Plus accepts points, amplifier and mag pickup inputs and will run on 4, 6, or 8 cylinder engines. It 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).

Features:

• 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
