Hi. I just started tuning my new wideband setup on my audi tt 225.
1.8t k04 turbo.  bam ecu file.   bea engine ecu.  amu engine (wb swapped).
tuned with tunerpro

Runs good, but i just did a log of 4th gear pull,  then a 3rd gear pull.
As you can see from the attached log,  high rpm AFR is around 11.0-11.3 in 3rd gear, 
but it's as high as 11.8 in 4th.   what gives?

Is there some table that tells the car to lean out or change AFR depending on your gear, or depending on your speed???

Thanks for input.
