Yeah, I've done quite a bit of 2nd gear checking. Usually KR begins with any boost, even in 2nd.
If I understand correctly AE is an additional initial fuel dose compensating for PID lag. After this it does nothing.
That is what I do for PE tuning. I haven't spent much time with PE tuning yet because of sub PE KR. I was getting KR at 15% throttle.
I'll try to grab a 2nd gear scan and post that.
To the suggestion of releasing TC lockup earlier in throttle, I agree to a point, but not to the point of it releasing every time you hit resume accel in cruise control.
Thanks for suggestions guys.
