Dual light speed ignition system

I am using dual plasma III, interconnected, with the magnets on the ring gear sensor - semi installed and not flying yet. I wanted to follow along with the discussion, though - are you seeing any issues?
 
Dual plasma III
same here, and super happy with the set-up. Ran a dual Plasma II for 2'300h on my previous engine with no trouble at all. Simple, reliable, light, no mechanical connection to the engine, no bearings (...), etc.
Only "mandatum": thorough and careful install (wiring, magnets and hall sensors, etc), and care/testing the standby (or alternate, or... anyone's choice of wording) battery.
I'm using EarthX's smallest (ETZ5G, minute and super lite), and religiously test it (running on it only for 30" whilst reading V decay on the dedicated V output) prior to any flight.
Did the recommended flight test a couple of days ago, flying 1hr with the ignition only powered by that tiny battery: initial 14.3V, 60 minutes later 13.1V.

Thank you everyone. The issue has been resolved. I wasn’t able to start the newly mounted engine due to the spark plugs connected in wrong coils. After reading the manual for two days and 3 people still couldn’t figure out. May be too dumb of us. But VAF is super awesome. Carl got on a FaceTime and solved in 10 mins. This forum is awesome.
 
Now that I got it started, I am having some issues with the fuel pump. I have a low pressure pump Airflow performace and then it is connected to Andair from the tanks to the facets high pressure pump. ECI IOX 360 with dual LSI Plasma 2+, the low pressure pump is connected to the Ignition switch and when I start the engine on off position, it is fine but as soon as I turn on the switch, it dies.
