The following article is about the MSD Honda TRX400EX Ignition System and its schematic diagram. The Enhancer Ignition System for the Honda 400EX produces a high output spark that is approximately double the stock spark output. This increased spark energy allows the use of richer fuel mixtures or even exotic fuel such as alcohol. The MSD Ignition will put out approximately 30,000 volts to the spark plug.
The MSD Enhancer Ignition system allows you to program an ignition timing curve. Changes in altitude, compression, fuel octane or a number of other variables requires that the ignition timing be compensated. The Enhancer allows you to advance or retard the initial timing as well as designate a different timing curve to increase overall power and performance.
