    		Maximize your vehicle’s distributorless ignition system (DIS) with MSD’s powerful new ignition controls; the MSD DIS-2  These Ignition Controls feature Multi-Channel capability, and can deliver up to 480 volts to the primary side of most DIS type dual output coils. With its two channels, the MSD Digital DIS-2 is designed for use on all 4-cylinder applications using 2 coils.

    These new DIS Ignitions feature the race proven capacitive discharge, multiple spark design of the MSD 6 Series Ignitions. Each spark of the MSD Digital DIS Ignitions is packed with up to 115 millijoules of spark energy, resulting in more efficient combustion to produce more power. To improve low speed throttle response, smooth out the idle and stop low speed spark plug fouling our engineers included MSD’s proven multiple spark discharge feature. This race tested design produces a series of full power sparks that last for 20° of crankshaft rotation to ensure complete combustion of the fuel mixture!

    The MSD DIS Ignition Controls are an incredible breakthrough for  Eclipses. With the proven MSD Ignition high speed RISC microcontroller technology and years of performance ignition experience, the MSD DIS Ignition Controls will make a great addition to your car!

    SOFT TOUCH REV CONTROL
    The DIS-2 features an adjustable built-in Soft Touch Rev Control to protect the engine from overrev damage caused by missed shifts or broken driveline components. This feature produces a smooth rev-limiting action by randomly dropping one cylinder at a time and then refiring that cylinder on the next firing cycle. This feature is easily adjusted with simple program switches mounted on the side of the unit.

    TWO STEP MODULE SELECTOR
    The Two Step function of the MSD Digital DIS Ignition allows you to activate a low rpm limit while staging and waiting for the light to turn green. This popular feature gives you a distinct advantage over your competition by permitting you to control your engine’s rpm precisely before every launch. With a fixed rpm limit at the starting line, each launch will be consistent and quick! The rpm limit is easy to adjust in 250 rpm increments with switches built into the side of the housing.

    PROGRAMMABLE TIMING CONTROL
    Precise timing control is essential to producing maximum engine power. With the addition of nitrous, turbos or supercharger systems, timing becomes even more critical. To get the most out of your engine, the ignition must be able to compensate for these extreme changes in cylinder pressure throughout the engine’s entire rpm range. During low speed operation, the MSD DIS Ignitions use the factory ignition to control basic timing functions. Once maximum timing is achieved, the DIS-2 can be programmed to retard the timing at a specific rate and rpm point to prevent engine damage due to detonation caused by excessive timing.

    LED MONITOR
    A built-in LED monitor is a useful tool to determine the status of the charging and ignition systems. When the battery voltage drops below 8 volts, the LED will begin flashing at a rate of two times per second, letting you know that the charging system is not operating properly or that the battery has failed. Also, if any of the ignition’s channels lose their trigger input, the LED will flash at a rate of one flash per second.

    IGNITION INTERRUPT
    To prevent accidental or unauthorized starting of the vehicle, the MSD DIS Ignition systems feature a driver activated ignition interrupt feature that can be used as an anti-theft device. When activated, this feature will prevent the engine from starting by disabling the ignition’s voltage output to the coil.

    EMI NOISE PROTECTION
    As with all MSD Ignition products, additional protection from Electro Magnetic Interference (EMI) has been added to the design of the DIS. Special circuitry filters out unwanted noise that commonly causes other aftermarket ignition systems to false trigger, operate intermittently and even fail.

    DIS-HO Ignition Controls

    The popularity of small displacement, high rpm, turbocharged racing engines has created a need for an even higher output ignition for DIS systems. Wherever there’s a demand for powerful sparks, MSD is there and the answer is the MSD DIS-HO Ignition Controls. Like the popular MSD DIS Ignitions, the DIS-HO models are designed for vehicles with distributorless ignition systems with two, three or four coil packs. The HO models produce 170 milliJoules of energy and deliver 470 volts going to the coil packs, plus the CD circuits deliver a series of multiple sparks below 3,000 rpm! This combination is more than capable of completely burning the fuel mixture of engines with through-the-roof cylinder pressures. Along with all of it's spark power, the MSD DIS-HO Ignitions have some great built-in programmable features. There is an ultra smooth Two Step Rev Control which gives you the ability to set two rpm limits so one can be set during a holeshot while the other comes in for top end protection. There is also a timing retard feature that allows you to pull timing out of your engine at a specific rate and rpm point to prevent engine damage from detonation.

                             Digital-6 Plus Ignition Control

    The all new MSD Digital-6 Plus Ignition Control embraces advanced digital technology to take performance ignitions into the future. No other digital ignition can match the power and efficiency of the all new MSD Digital-6 Plus.  MSD combines race winning experience with cutting edge technology to create the most powerful Digital Ignition available! The Digital-6 Plus isDigital Done Right!

     The heart of the Digital-6 Plus Ignition is a 15 Megahertz microcontroller, the fastest of all digital ignitions. What this means is the controller analyzes up to 15,000,000 critical instructions per second! This is over three times the speed ofcomparable ignitions and produces the most accurate trigger signals, timing and rev limits possible.
     
    MSD engineers have spent an endless amount of time testing the components ofthe Digital-6 Plus to ensure the most efficient and reliable operation. 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. 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 up to 535 volts. 

    When used with the MSD Blaster HVC Coil, PN 8252, 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 glows in the cylinder for  up to 20° of crankshaft rotation. This incredible heat ensures combustion to produce  great power, quick throttle response, smooth idle and quick starts.  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.
