MSD has activelyreacted to this problem by introducing theNitro programmable ignition system. Thissystem combines the benefits of a capacitiveDischarge ignition with all the advantages ofan inductive ignition; better and longersparks. For this kind of power two ignitioncontrol units are required; one for the CDcircuits and programming controls andanother with the inductive circuitry.Togetherthese controls send a unique spark to twohybrid coils. These coils have to be used incombination with the Nitro ignition tooptimize the ignition, fuel efficiency andmotor management. The Nitro system alsoprovides racers with limitless tuningpossibilities through advanced PCprogramming with MSD pro data+ software.Program timing curves up to 0.1° per 100rpm, program shift points and retard stagesand different rpm limits. Ignition unit, coils,pick-ups and rotor all sold separately.711830 Ignition coil.

Your engine will run smoother,burned points are history, plugs will lastlonger and troublesome condensers areeliminated.You can expect consistently betteroperation at a lower maintenance factor.232282 Dyna Ignition BoosterDYNA RPM LIMITERDyna's RPM adjustable from 6.000 to over12.000 RPM by easy to operate dip switches.This new version of the RPM limiter has anadditional output stage that worksindependently of the RPM limiter.The outputstage can even function when the RPM limiterhas no power. It works on a simple 12 Voltsignal and can, for example, be used forclutchless upshifts. The Dyna RPM limiter isdesigned to prevent bent valves and blownengines due to overrevving or missed shifts.The limiter will work with any electronicinductive type ignition and can use up to 4Dyna blue, low impedance coils. It does noteffect engine performance until the pre-setmaximum revs are reached.At that momentthe spark is killed until the RPM's drop tounder maximum, the spark is then reactivated.Note: Can not be used with CDI ignition.232266 Dyna Single stage RPM Limiter05Electrical & Ignition711829 Programmable ignition unit V-Twin.
