Okey Dokey..
So, ignition timing seems completely normal while lightly accelerating and coasting. Hovers around 25-30 at cruise, 40-50 at 3k RPM when stopped, and close to 5 when on decel. Only when under heavy load does it drop like a rock.
lswing, your requested block 93 is here (bottom row)
The camshaft adjustment is off at idle, and comes on and stays on during tip in, cruise, and acceleration. seems normal. when adjustment status is on, each bank adjustment goes to +21*KW or so. binary, on or off. no inbetween
The block 93, started out with bank 1 at -10*KW and bank 2 at -4*KW, but after warming up changed to the above levels, and never moved, no matter what state the engine was in.
Below, we see the system failed the knock sensor test.. and you can see voltage at 5 and 6 at the .234 as stated, while all other cylinders varied with RPM/load.

Mark, here is your requested log.. short 3rd gear pull. we can see that ignition timing pull is progressively decreasing, not in line with timing retardation by cylinder. pretty much right when i give it partial throttle, all cylinders peg at 15.8 for retardation.

OKAY. I feel like an idiot, once again. Found the problem - crushed/cut wire to sensor. not quite sure how it happened.. can probably repair it, don't really feel like pulling the intake manifold. I'm 99.9% sure this will take care of the power issue. Will report back once done. Thank you all again for helping.

Good work, well done I really hope this fixes your problem. I know what it's like to finally put the engine back in after 6-12months pulled apart and then looking at all the pics to try and figure out where everything goes.
P.S. block 93 shows that the timing is a bit out of wack between the 2 banks but not enough for it to be a problem, they will get further out over time but nothing to worry about unless it throws a code.
Wishing I had a proper garage to pull off this big of a job. Glad you (hopefully) found your issue.
Personally not looking forward to the 5-digit parts & labor bill I know is on its way when I decide to do a full button-up maintenance :\

Fixed the wiring over the weekend. Re-soldered all 3 wires to the knock sensor. another problem was the plug, it had a crack in the flange, so it wouldn't always click all the way in if wires were tugging on it. All sorted out now, runs like a bat out of hell!!

Nice! Should be there soon myself. You ever get the temp sensor fixed?

Good deal. I'm not sure it's what caused my new trans to fail in 8 months, but it was the only code or issue that's shown up. Maybe we'll find something more upon tearing the broken one apart. What I found repeatedly in searches on the issue was belief it causes issues with the TC not locking up at the right time, therefore transferring too much power or staying open and cooking the fluid, then cooking the clutches.
