In CL AFR will float +/-1AFR that is what the NBO2s do,
AFR will never be solid like commanded AFR is.
In my experience it can be difficult to distinguish rich/lean by smell.
If adding/subtracting the offset in the sae_generic.txt or your calc_pids.txt
does not change things then check to see if the analog ground gives 1volt.
I don't know how the ADFILTER in the V2 works or what setting is best.
I think the FJO can be used with serial connection, have you looked into that?
