In those logs there was no major knock. Now that you fixed the ebcs take another log to confirm everything is ok.
If everything will look good in the logs then you may need to look somewhere else for the clapping sound: engine mounts, axles, radiator frame, or anything loose in the engine bay which may clap when transitioning from acceleration or cruising to engine braking.

These engines are known for VVT actuator failure which can result in a clacking sound under the hood.

Indeed, knock is pretty significant. You may be running a bit too much timing for the fuel you're using. Copy the timing tables from a 91 octane tune and try again.

Please use this logging preset next time you take a log:
