[QUOTE="Rednaxs60, post: 231814, member: 4617"] Further to my last, I have been doing on-line research and have found a few additional tidbits to support my first post. I have been querying the coil-on-plug (COP) dwell time and spark duration for a COP. The COP dwell time is recommended to never be lower than 1.5 ms. Jury is still out on the COP dwell time, but I will be using the finger test to determine an appropriate dwell time. if the COP temperature using the finger test allows me to touch the COP without burning my fingers, all should be good. I have viewed YouTube videos regarding testing for this and may give bench testing a go. I have increased the COP dwell from 1.6 ms to 2.0 ms and think I have seen a difference in engine operation. The spark duration is set at 2.0 ms. I will be increasing the COP dwell to 2.2 ms, use a small temperature gun to check COP temperature in conjunction with the finger touch test, and make sure I do not overheat the COP units. Increasing the COP dwell time, increases the primary current into the coil. Cheers [/QUOTE]
