At what rpm does this process take place. When I cruze at around 90 and at 4200 the car goes lean. Is that the trans. point ? Is there a way to fix that ? Beside going to a standalone. Thanks(dunno)

It's not RMP dependant. It's load dependant. 100% throttle kicks it into open loop.

Going standalone is the best route...

So when I am moving along at that speed the position of the throttle might not be 100 % open. So if I use my SS I can adjust the AFR to take care of the lean pt. What do you think ?

Ya that is what it's designed for... A voltage clamps works well too if you don't have the AFC.
