My understanding is that the system is a multi-spark similar in theory to aftermarket high-perf ignition systems used in race applications (manufacturers include Daytona Sensors, MSD, Holley, etc). Lower RPM is where the effect is seen, and once an engine reaches about 3k rpm, the spark events become so constant that multi-spark is no long possible. I can see where this is another tool in the arsenal of performance and emission control.

In my case, the insulation was cracked and destroyed. You could see the arc scars. Once the spark demand of the coil pack began to increase, the electricity found the least path of resistance and the misfire was experienced. Was interesting to see that the misfires would occur right at 3250 rpm per Xentry.
