Digital 6-Plus Control Universal Soft Touch 2 Step Rev Control 1 Stage Retard Control Start Retard MSD IgnitionEvery 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
