The heart of the Digital-6 Plus Ignition is a 15 Megahertz microcontroller, the fastest of all digital ignitions. What this means is that the controller analyzes up to 15,000,000 critical instructions per second! This is over three times the speed of comparable ignitions and produces the most accurate trigger signals, timing and rev limits possible. The 6 Plus produces more power with less current draw (20% less) by incorporating an IGBT coil driver that can be controlled for improved coil saturation control. Also, power MOSFET technology and high frequency magnetic converters require less input current while producing more energy and voltage. 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, 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. To prevent any chance of Electro Magnetic interference (EMI) a filter circuit is made up of state-of-the-art magnetic suppressor components. This, combined with the more than competent microcontroller checks and rechecks inputs many times to determine "clean" signals before making any compensations. The magnetic input also features a unique microcontrolled feedback circuit for total EMI-free operation.
