MSD's legendary DIS series ignition boxes feature a capacitive discharge ignition design. Straight away from the conventional inductive ignition systems, these ignition boxes to not require the coil to store up and step up the voltage to maximum strength in between each cylinder firing. Also at higher rpm since there is less time between charges, you can expect a consistent and repeatable spark pattern.
The MSD ignition features a capacitor which is quickly charged from 460-480 volts and fired all within one millisecond. Providing maximum spark and consistent performance is what has made MSD an industry leader in ignition systems for combustion engines.
Perfect for turbocharged, supercharged or nitrous applications, these DIS ignition boxes are the favorite of many Evolution, STI / WRX, and SRT-4 drivers who want maximum spark for their performance vehicle.
Multiple Firing : MSD Digital DIS Series Ignition Boxes produce full power multiple sparks for each firing cycle in each cylinder.
Accurate to within 20 deg of crankshaft rotation for precise power delivery and fuel savings
Rev Limiter : All DIS systems are equipped with a built-in adjustible Soft Touch Rev Control - adjustible to within 100 rpm increments and using program switches on the box's end panel.
The Soft Touch produces a load-free rev limit that is accurate to within 10 rpm of the selected rpm.
Tachometer out : These Digital Series Ignition Systems feature a tach output terminal on the side of the unit. This terminal provides a trigger signal for tachometeres, fuel injection, shift lights and any other add-on devices that require a 12-volt square wave rpm signal with a 20 deg duration.
Some vehicles may require the use of a ignition adapter to properly translate the signal to your vehicle, for further details ask your sales rep.
