I have recently installed an ez steer on a lexion. This is my 1st ez steer and am having a little difficulting getting it "dialed in". I have gone through the wizard and have it engaging and keeping the line pretty well. Occasionally when I engage it has a total meltdown and starts weaving around aggressively. I stop it. back up and re-engage and it aquires the line perfectly. I wonder if it has something to do with the wheel angle when I engage.  I try and have it as straight as possible prior to engaging, but something is going wrong somewhere.

I have the online aggressiveness at 95, but I have read in some of the tech releases that 75 would be better for a combine???
wheel angle/turn is set at 9 or 10. started at 20 and it wandered 100 yards before sobering up...could I reduce this some more?

What are some of the settings others are running in combines.
