6A-Ultra Ignition Control Box, Universal
The Ultra 6A Series continues to use a high speed controller that can make extremely quick compensations to the output voltage, multiple spark series, timing and rpm limits while maintaining precise timing and accurate rev limiting. The circuits and controller of the MSD have been thoroughly filtered to create protection against Electro Magnetic Interference (EMI). The Ultra 6A Series feature a capacitive discharge ignition design. The majority of stock ignition systems are inductive ignitions. In an inductive ignition, the coil must store and step up the voltage to maximum strength in between each firing. At higher rpm, since there is less time to charge the coil to full capacity, the voltage falls short of reaching maximum energy which results in a loss of power or top-end miss.

  • Plug and Play upgrade to current installations with a 6201, MSD 6A
  • New processor and board design provide a highly efficient ignition, minimal heat and max spark energy with less current draw
  • 60% smaller and 50% lighter than the MSD Digital 6A (688 grams vs 344 grams)
  • High rpm operation and maximum output using the Blaster HVC, PN 8252 or HVC II, PN 8253
  • Powerful capacitive discharge of multiple sparks improves performance, and ensure complete combustion
  • Consistently high spark energy of 135mJ to 150mJ for every firing, from idle to redline rpm
  • Easily installs on 4, 6, 8-cylinder engines with distributors
  • Operates on most 7 to 28-volt electrical systems
  • Connects to points and magnetic pickups
  • Fully protected against an open coil, shorted coil & open load
  • Compact design - full MSD power
  • Quickens throttle response & improves starting
  • Tach Output to drive an external Tachometer

MSD Performance

Racers never stop experimenting as they search for every way to wring out more power or handling performance to to gain an edge over the competition. The team at MSD is no different as we strive to deliver the products you need to meet your performance goals. We continue to innovate and invent components and technology that deliver performance and reliability with products that are easy to use and install. Over the course of 40-plus years, MSD Performance has been driving the development of innovative components that helped shape the way our cars race and perform. From super speedways to road courses, land speed racing to top fuel dragsters, and of course your traditional hot rod, MSD has provided the components to fire nearly anything in motorsports. Early on, MSD focused squarely on ignition systems with revolutionary products like the multiple sparking CD ignition, timing and rev controls, billet aluminum distributors and the Pro-Mag, an incredible breakthrough in power and endurance. Today MSD is developing electronics for your entire powertrain. The Atomic EFI systems for the LS engine platform and throttle body are now complemented with a transmission controller. Our DynaForce Starters and Alternators ensure that your engine cranks over to fire up and the Alternators keep it charged. MSD is poised to deliver components that work and communicate together to provide performance and value.
