Any PID to see the actual (not commanded) AFR ?

Hi,

Please advice what PID I have to select to see and log actual AFR at O2 sensors 1 (bank 1 and 2)

Thanks in advance.

most vehicles do not report actual AFR, what vehicle is it?

no, you need a wideband sensor to see the actual AFR.

Thanks, because I do worry. When I see the picture with actually flat desired AFR and knock retards when engine goes to load ... I do worry.
During the whole log (run) I saw only one moment where AFR went to reach.

Please see the pics just on the fly ( flat AFR)
