Then tested the CAM output signal to the ECU, by waiving a screw-driver tip in front of the trigger. It's reading 4.7X volts. I also swapped in another sensor to check, still the same.
So I have the cam input set at "MS3 cam in", continuity between the sensor and the harness, output signal being created, power and ground.
What am I missing in this equation? I can't imagine there's an air gap on the cam sensor, it just bolts to the valve cover, and is sitting flush.

I decided to take wiring out of the equation.
With known good 12v power and ground, I apply each to the pins on the sensor.
When hooked up to the multimeter, the center signal pin shows static output at 10.XX volts. Waving a metal screwdriver in front of the sensor changes nothing.

Cam signal is now in and ok.
However, on that log, it appears you have an issue with the crank signal, on the latter half of the log. I can't tell but if you have a somewhat weak battery, that could be it.
Can you grab a longer log?

The 10 seconds for OEM cars is not a protection for the starter, it's more a protection for the oil and cat in case the problem is the with the coils. I usually ask for a 10 sec log to diagnose cranking issues.

I enabled test mode, selected coil A (1 and 4 trigger I believe), output interval 199ms, rpm 600, coil testing mode "one", Dwell set at 5ms.
Number 1 wire (powered by 1/4 coil) has a plug in it, grounded on stainless racing beat header.
Tried on "coil" A/B/C/D. No spark output. Burn page 1 failed - displays iff I hit "burn".

Okay, new info.
I hooked up the 94 coil pack into the stock wiring, attached a plug wire, and test-mode gives me spark.
So, I then wired the 01+ coil-on-plugs into said stock wiring, test mode does not trigger spark. I tried both coils (powered via the 1/4 wiring), still no spark.
Is it reasonable to believe that I have two dead coils? Spark outputs through stock coil, wire in COPs, no spark.
When looking from the drivers side at the engine bay, the top plug in the COP connector is 12volts, then signal, then ground.
