Closed Loop Fuel Disabled due to LTC "Unavailable"

My M1 has stopped seeing the LTC in Closed Loop Fuel control.

The LTC has the latest firmware,(Re-downloaded and installed this morning) and shows functional in the LTC config tool without any faults.

I can see the LTC in M1 Tune, and can data log lambda without issue. But closed loop is not able to see the sensor since yesterday.

Just to make sure it wasn't something I changed in the tune, I loaded a file from 2 days ago, and got the same result.

The screenshot below shows what I'm seeing with the engine running. (Please excuse the help screen)

The issue was me.

If I had used a tune file from 3 days ago, I would have found the issue quicker.

I accidentally filled in a row of the Post Start fuel compensation that resulted in continuous compensation with the engine fully warmed up.

Hopefully this post saves others some headache....
