Excessive knock

Morning,
I was datalogging and noticed a lot of knock. I pulled the timing but there's even knock close to idle. Can you guys take a look at the map and datalog and let me know if i'm missing something. Really concerned if i have a mechanical issue or my knock sensor is too sensitive?

Thank you.

Set up is a completely stock 08 civic Si + bolton turbo kit with a huge wastegate leak. Max boost is just 1.7psi. With the minimum boost/load i don't think it should be knocking this bad.

It probably is mechanical contact causing the noise. I'd check the exhaust system is not hitting anything under flex.

Thanks it really had me worried that the knock count was going crazy.

Have a great 4th July
