Fired right up once i had the fuel pump relay signal jumpered from the adapter board. Used the key in the column.

yeah making progress.
FINALLY discovered my running rough issue.
I had checked timing, but had to repeat it. Turns out the flywheel is off location. Either I installed it wrong, or the custom flywheel has the orientation off. Set the base timing at 20 degrees finally, and it purrs like a kitten.

Put my latest tune and log on the database.
Changed to batch injection, now fighting lean condition. Can't get enough fuel.
Must be missing something simple.

Chasing issues. Lean running turned out to be no spark on 1-6. Found bad coil, replaced, and still no spark of life.

Please confirm you are using the "bench test" buttons to click things individually without trying to run the whole thing

We have been running it for a few weeks now. Have not used the bench test for this current issue.

Followed the bad coil, dizzy was good, traced wires back to the ecu adapter. Pulled it out of the case and found the issue. Talked to Andrey and we have a plan

Well, you get the award for most brutal IGBT damage I've seen on rusEFI.
Unfortunately I witnesses some igniter damage myself this Saturday. I suspect it was a combination of loose/lame/random patch cord and some unresolved software issue maybe https://github.com/rusefi/rusefi/issues/4310
In the mean time please twist both ETB motor wire pairs in the patchcord between your proteus and M73 adapter that could be contributing to the unclear problem we are facing.
