6520 MSD Digital 6-Plus Ignition Control Universal - Soft Touch 2 Step Rev Control - 1 Stage Retard Control - Start Retard. Every spark of the Digital-6 Plus Ignition is packed with 135 millijoules of spark energy and 535 primary volts.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).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 Ignition Control combines terrific power, digital accuracy, and great accessories making it ideal for street/strip applications.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.. CARB EO # D-722-2
