Honestly, the datalogs should tell you exactly what's happening, if they don't, something is seriously wrong.

Thats one of the problems, the AMOUNT of interference....its zipping logs on BOTH the Ecu and the Wideband logger totally seperate units, its THAT much.
It happens over about 7 grand, below that its ok, but well, lots of EM, it looks like thats solved however.
8 20 amp igniters zapping over 7k and 16 plugs well....a lot of EMI,probably more than its obvious you can imagine. Im pretty familiar with EM and how to shield it, from radio electronics and all my XY expereince when my dad owned his vending company (atari XY games were notorious for that) and it looks like my "super nuclear Drooze 100MEV Faraday Cage" solved it, but hey no hating, it works.
The OPTIONS arent plentiful, not for a hot spark, not on this engine because of the coil rules in regard to numbers, so if you know a way to fire 16 plugs with 8 coils let me know, and a coil that over 65k volts on both sides. May be an import unit but we cant find one.
So the option is use a hotter igniter and spark booster, but with the igniters they were enough so we removed the spark booster, and we were still good.
Now for a new and improved non-trackside built one.....(em shield) Time to dig out all my old HAM radio gear.....(I KNEW it would have a use again !) I had to make this one out of roof flashing, alluminum window screen, anti static mylar coated bubble wrap (sun shielding) and a few other handy items I grabbed at Home Depot.
Its enough EM its zapping the flash ram....seriously.....And Not just on our ECU, but other systems, including a laptop if its in the car......when the FCC comes knocking Ill know why....its like running a magnetron in the open.
I can also throw an arc HOT across a .060 gap at over 8k....so no spark issues
But the lack of spark issues are causing other issues,
I got logs outta the last "Catastrophe" however.......so now I can print em out and hand em to the old man any time he gets "punchy"
Were aware of the issues and working to resolve them....that didnt cause a rod to aerate the pan, other things, mechanical did.....simple, 2 seperate issues.
