    A/f sensor 1 ratio number Accessport

    Recently installed Cobb ap v3 stage 1 Aem Acn91 map on 14 wrx 265hp motor. Driving to work, I got the following numbers.

    A/f sensor 1 ratio: 11.14/20.33. The high number is achieved on. De acceleration with no throttle. This seems lean to me.

    Boost: 17.28 max.

    Feedback knock: -4.20/0

    Inj duty cycle: o/83.89

    This is at sea level in Ca, about 60 degrees ambient temp. I only have 650 miles on it so I am shifting at 4k rpm till I hit 1000 miles and change oil.

    Any comments on the numbers? I am going to add Dam to the monitoring parameters and report back.
