I would try replacing it and see what happens

That is your knock sensor... Where's that "well, there's your problem!" meme??

that definitely has to be his problem

Yeah I know looks bad. I really don't know how the lack of the polymer stuff behind the knock sensor would cause it to malfunction, but then again I don't know too much about knock sensor mechanics...
I really hate just throwing parts without any more evidence, but I caved in and ordered a Beck Arnley sensor. 60 bucks let's see what it does.
Also, "iracemine"
I know this is a late reply but I don't have the ZE crank pulley, sorry!

OK, so I slapped the new knock sensor in. Thought I'd show some pictures of the face of the old knock sensor. As you can see, that brown polymeric material was also on the other side! What could have caused this???
Anyways, the result????
STILL pinging(rlaugh)
It's OK, it seems like I needed to replace that sensor anyways. I think on average it pings less, but to confirm that, I would have to do a "negative control", ie put 100 octane in again and see the difference. Someone in the very beginning of this thread said to check the cam timing. I thought that was kind of absurd, but now it's starting to make more sense. I've actually spun the engine by hand (wrench) with the valve cover off to see if the cam I and E marks line up at some point. They do, but I can't confirm that it's at TDC; I don't have power tools or means to get crank pulley off and mainly back on...
Back to the drawing board.
ps - on tangent, I would like to say that that adding the FS ZE intake manifold to the FS ZE engine has made some difference. It definitely did not make a world of difference (and I wasn't expecting that), but I can feel the power band is a bit flatter, especially at WOT. I assumed that installing the manifold would increase top end performance due to the variable resonance chamber thing, but I am pleased to report that the high end performance not only stayed the same or slightly increased, but that the mid-rev torque and power increased. The higher mid range power is what I like about the manifold the best.

Can't believe this is still going on. Just get a fricken aftermarket ECU and fix the problem.
Its like the definition of futility. Keep posting and complaining about the problem but knowing the solution to all your problems and doing nothing to solve it.
Not only that but you lack the intellect to comprehend that going WOT on and engine that pings is like giving an 80 yr old with heart problems viagra.

There's timing marks on the plastic cover and crank pulley too. (at least there is on the stock engine)
