Looks like you have all the advice you can get for a system that is functioning properly. If you still have problems, there may be a soft electronic component or something like that. I hope there is a good, competent dealer or performance shop that can help you out in that case. I chased an intermittent problem with one of the ignitions randomly shutting down in my airplane. REALLY frustrating, and a little dangerous. Finally sent the whole EI control box back to the mfr, and sure enough, one of the complex IC chips had an intermittent open circuit. I never would have fixed that on my own, even with lots of electronic/circuit board experience.
