Ignition timing corrections

I am FBO e50 custom tune, wanted to know why I am getting a lot of ignition timing corrections at idle.

That's a data log at idle, this has been happening for a while.

New:
plugs
coils
valve cover/gasket

Wide open throttle is perfect, just idle is rough

There are no timing corrections in that log...

That channel logs actual timing advance not timing corrections (knock).

Timing at idle will bounce around as the car uses various feedback to control idle load.

Log "fuel mode" next time and send the logo off to your tuner with a note that you have a rough idle.

It's in the options. You can select whatever parameters you want to log. Adding fuel mode as a logging channel can be helpful for the tuner.
