First off I'd like to thank @SlowE93 and @doublespaces for posting about bimmerlife tuning Motorsport Ignition Upgrade kit issues and solutions. While there had been misfire reports on various forums, we had not experienced them (yet), but were planning to investigate. Misfires at a Sunday track event jumped ahead of the measurement session. Again thanks to those that have been posting their observations, as well as for @Alex@BimmerLifeTuning being responsive to my messages over the past week.
While measurements gave us some clarity on what's actually going on, those measurements also inform some speculation on our part as to why misfires are experienced by some, not by others, and why for some the car runs fine, and then begins to misfire.
With that said, I'm going to post what Barry Battle and I found yesterday evening, with measurements and photos, along with what we found to be the solution for us. We ended up working on @MDORPHN 's 1M which is One Lap of America bound, instead of my Z4, which I'll fix later this week. I hope this is helpful to others. I'll make multiple posts on this thread, as follow-up. I hope the details are helpful to other BL coil owners.
