Unable to get Harmonic notch and proceed for autotune

I performed the FFT, but it was unable to set the harmonic notch.

Also, when I try to do autotune, it not even start to twitch and just shows failing to level. I guess it would get solved after setting a good harmonic notch.

Here is the log file : log file
I really appreciate any help you can provide.

Why? Disable FFT and use ESC telemetry RPM. And you need to enable Batch Logging to collect the data. And update to latest Stable firmware.

Okay ! I will use ESC telemetry data to setup the notch filter.
