It's definitely knock unfortunately. My last motor threw a rod bearing and it's the same knock sound but very brief. Also it's much louder than the induction noise.
It's very much looking like the car isn't getting fuel fast enough to keep up with the throttle snapping open so it leans out for a split second and knocks. Maybe my injectors are a little clogged or something but the issue seems very much like a lean condition on the throttle blip. Once the injectors are kicked in with a bit of revs you can jab the throttle as hard as you want and it won't knock, even at 1k rpm. With how common this issue seems I'm surprised there's not much answers out there.
Won't have a data log or video today, but I'm curious to see what the AFR's are gonna look like when I do get the logs done.
