I agree with you on the AFM. But putting a known good one should have made that go away. But it didn't. I don't have a spare turbo ECU to swap that out to cross that off the list.

^It should have unless there's a open circuit in the harness wiring somewhere between the AFM safety switch and the ECU. Swapping out a good AFM in that case wouldn't isolate that problem.
