This sounds like a good bit of deductive reasoning. I had similar problems
getting my 16v conversion to run, and it turned out I had fried the main
brain box.

If you know someone with spare brain boxes, knock sensor and the main one,
try swapping them and see if you can get the correct readings at the DPR.
Sounds like you have done some good detective work, start with KS.

Rare as it seems, it CAN happen.  In my case, I had made some bad
connections when wiring the engine in and it allowed a ground to happen that
should not have.
