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.

  • 15,000 RPM with 14.4 Volts
  • Quickens throttle response & improves starting
  • Compact design - full MSD power
  • 12-15 Volts, 7 Volt Start

  • 1.1 Amp per 1,000 RPM
  • Fully protected against an open coil, shorted coil & open load
  • Tach Output to drive an external Tachometer
  • Powerful capacitive discharge of multiple sparks improves performance, and ensure complete combustion
