A couple times in the lifetime of my car, I've had a startup knock on my car when it got hot out. Like when the car had been sitting out in 90-100* weather. I think its when you have bad gas or something is just out of range for a second during startup, like maybe exhaust VVT out of range.
I'd try some fresh fuel and keep testing on it, record stuff with a camera, put a screwdriver to the engine and put an ear to the end of it, and maybe get a OBD reader and take a reading on both AVCS advance angles.
