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.
