If I'm understanding you correctly, you are saying that the commanded CL AFR has absolutely no bearing on what the car will actually run once trims are accounted for.
Thats exactly right, if its working for you then something else is wrong on your car. Either your wideband is off or your o2s are bad. If your narrowbands are still switching at 450mv and your wideband says its lean then it's your wideband. If you aren't switching at 450mv then it's your o2s. Care to post a log?
