Plx wideband afr, trying to log afr on efi live Newb to this im sure i got it hooked up rite. I try to log data on efi live with plx the afr says 14.8 and stays 14.6 to 14.9 all the time even at wot. Commanded fuel pid is correct and even o2 mv are correct around .860 to .880 at wot. But the afr is not rite or is it? I dont think the o2s could lie about what theyre seeing. Just tuning a pretty stock 02 chevy silverado z71 nothing but muffler on it. Put wideband in bank 2 sensor 2 hole. Idk what to do about this its reading but not what it should be reading at wot. If anyone has anything please help. Thanks
