lambda readings / ignition timing
Don't know much about these things (yet) so please enlighten me !
02 sensor :
My lambda readings are between 0.69 and 1.49 but that seems a bit odd to me. Shouldn't lambda be between 0.90 and 1.10 ? I have read that ideal lambda is 0.90.
Ignition timing :
have seen timing between 0 and 47° . Isn't that also a bit 'conservative' (knock correction is ONLY -0.5)
(ps. it's for the n/a Impreza)

O2 readings should be between 0.0 & 1.0.
Timing will vary for engine load & rpm....so it's hard to say where it should be. Usually you check it at idle to verify everything is fine.
