wideband readings

[jumaaneface]

Curious about what most of you guys with wideband o2 are seeing as AFR out of boost under normal driving conditions.

I'm seeing 14.3-15.1 when cruising
16.1 when shifting then bumps to 13.6 before going back to 14.7

Asking because I couldn't find much information on the car and I'm barely hitting 20mpg with city driving.

Thanks

sounds normal to me

I wonder what had been causing my bad fuel mileage then..
This car makes me paranoid

maybe clean air filter and sea foam car

Air filter isn't that old but I guess it could be a bad filter. I seafoamed it less than 8k miles ago

you're afr sure isn't causing poor mileage...if those are your normal day to day readings while driving lightly...you're staying in closed loop...so fuel wise, you're not going to get any leaner than that...car drives normally otherwise? No codes or anything?

so yeah...check your air filter...and stop driving around with your parking brake up?
