Today I don't have any codes, yet...it figures, as I was going to uninstall the Cobb anyway as I'm due for rear rotors and brake pads at my neighborhood BMW service center.
I have had this issue intermittently ever since I ran E85 on PROcede and now occasionally on my Cobb after switching back to a pump gas map after running E40. I couldn't open your logs but when my car isn't running lean or maxing fuel trims. I suppose it could also be an O2 sensor issue but that is just a guess on my part. Usually I just clear it and doesn't come back.
