Excessive knock

Post by smithgrinds »

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.
