Nitro Ignition The Nitro Ignition is the most advanced ignition system out on the market. The MSD Programmable Nitro Ignition system combines the benefits of a Capacitive Discharge Ignition with the best features of an Inductive Ignition. The result is an incredible 800 millijoules of spark energy for 400 micro-seconds. A combination of two ignition control units are used, the main unit houses the CD and Programming controls and another with the inductive circuitry. When the two controls are triggered they send their unique power characteristics to the two Hybrid Coils. These coils must be used with the Nitro Ignition and combine the two sparks to work as one. The CD side is primarily responsible for ionizing the spark plug gap while the current form both coils produce a high level of current and sustained spark. The Nitro Ignition uses a high speed RISC microcontrller to control the ignition's output while constantly analyzing the various inputs such as supply voltage, trigger signals and rpm. 800 Millijoules of spark energy Shift Counting Rev -Max Control (adjustment range 2,000-8,000 in 100 rpm increments) RPM/Time Delay Activated Switch Start Retard (adjustment range 0°-30°) Launch Retard (adjustment range 0°-30° in .5 increments time adjustments 0-2.5 seconds in .01 increments) Multi Stage Retard (3 retard stages) Stage 3 Retard Ramp (adjustment range 0°-25° in .1° increments rpm range 800-8,000 rpms in 100rpm increments) Launch Retard Ramp by Time (Adjustment range 0°-30° in .5° increments ramp adjustment range 0-2.5 seconds on .010 increments) Run Timing Curve (adjustment range 0°-30° in .5 increments time adjustments 0-2.5 seconds in .01 increments) Timed Retard Curve (adjustment range 0-12.5 seconds in .05 increments degree range 0°-25° in .1° increments) Individual Cylinder Management (adjustment range for both 0°-10° in .1° increments) Latching Overrev Shut Off Optional Boost Retard Curve Step Off Delay By Time (adjustment range 0-2.5 seconds in .10 increments) Time Retard (adjustment range 0°-25° in .05 second increments up to 12.5 seconds) RPM Activated Switch (ON Adjustment range 2,000-8,000 rpms OFF 2,000-8,000 rpms) PLEASE NOTE 2 PART NUMBER 4215 ARE REQUIRED FOR A DUEL PLUG ENGINE!
