Can anyone help me out?
As of now, I connected the PLX TX output to the S300 board.

Then I added a second display gauge, using the data from Input DI0.
To check if it works correctly, I disconnected the analog input from the PLX -> digital input works.

At "Sensor, DI0" I entered "Digital Lambda" and a range of 10-20.

At "Setting, Sensor Overlay" I selected DI0 (Digital Lambda).

But it won´t work. SManager still uses the analog AF Input for sensor overlay.
What am I doing wrong?
