The Ultra 6A Series uses a capacitive discharge ignition design and a high-speed controller that makes extremely quick compensations to output voltage, multiple spark series, timing, and RPM limits while maintaining precise timing and accurate rev limiting. Its circuits are thoroughly filtered against Electro-Magnetic Interference (EMI), and the compact housing is 60% smaller and 50% lighter than the MSD Digital 6A.
