Croustibat is an unknown quantity at this point
First, get a new knock sensor. I could not hear sound on the video, but starting that lean and keeping that lean could be anything fuel / air metering related. So ...bad fuel delivery (pump/injectors/filter/FPR), bad air metering (faulty MAF, boost leak, leaking BOV), or bad mapping.

I'd try with a known working z32 maf, too. If you know someone with a scope, have him analyze the maf response, i am quite sure you got a chinese copy and these are known to have a very poor, unfiltered response.

I'd check if your injectors are leaking past the orings. If they aren't I'd then check the maf.
Dude, when you don't know, don't post.

When the ECU detects knock, it pulls timing AND uses the alternate fuel map and timing map.

If injectors were leaking, he would have hydrolocked his cylinders too.
