When used with the a MSD Blaster HVC Coil Part, a spark with over 300 milliamps burns across the plug gap for 400 microseconds. Below 3,300 rpm the Digital-6 Plus produces spark that spans up to 20¦ of crankshaft rotation, producing greater power, quicker throttle response, smoother idle & quicker starts. To prevent Electro Magnetic Interference (EMI) a filter circuit is made up of magnetic suppressor components. This is combined with the micro-controlle which checks & rechecks inputs determine clean signals before making any compensations.
