MSD Digital 6-Plus Ignition Control

Part No. 6520

Autotronic Controls Corp.was founded in 1970 as a research and development company by two engineers from White Sands New Mexico Missile Range. The men and their other partners were working on a lean burn performance fuel system called the Electrasonic Fuel Induction system to help fuel economy of new and older automobiles.

ACC has produced the best performing and most popular performance MSD ignitions for over 20 years. The high energy performance spark of the CD design combined with multiple sparks resulted in a potent performance ignition. Not only did the multiple spark discharge ignite the lean fuel mixture, it made overall improvements in the engine's performance! Improved starting, smooth idle, less emissions and more performance power are benefits every car and truck can take advantage of, especially race cars.

Today MSD Ignition encompasses over 84,000 square feet! There are over 400 employees including an excellent core of highly trained engineers, performance technicians, assembly specialists and a host of performance enthusiasts at MSD Ignition.

Together, our team designs, develops, tests and manufactures the entire line of MSD performance products including MSD Ignition Controls, MSD Coils, Timing Accessories and MSD Spark Plug Wires and Accessories. MSD, housed in three buildings includes four MSD performance engine dynos, two MSD performance chassis dynos, complete MSD CNC and machining performance centers, modern shipping and packaging areas plus MSD performance assembly and MSD performance burn-in departments.

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. When used with the MSD Blaster HVC Coil, PN 8252 <http://msdignition.com/WorkArea/linkit.aspx?LinkIdentifier=id&ItemID=5101>, a spark with over 300 milliamps burns across the plug gap for 400 microseconds. Below 3,300 rpm the Digital-6 Plus produces a series of sparks that burns in the cylinder for up to 20 degrees of crankshaft rotation. This incredible heat ensures combustion to produce great power, quick throttle response, smooth idle and quick starts.
