logitech g25 turning issue

Hello. I went to the wiki and setup my steering wheel properly (it's a G25), but I'm still having one minor issue. When my actual G25 wheel is rotated to the left slightly, the in game car wheel is straight. It's like its off center, but I set the angle in settings to the same degrees that my wheel is configured to turn (900), and it does in fact stop in the right positions, it's just that it won't center.

(For reference when I take my G25 and set it straight, the angle of the wheel in game is 7%)

 

I don't know if this is related to, but I'm having -1% ingame, while this is what Logitech software shows (yes, with gamepad):


Ingame it starts as 0, but when I touch any button of the controller it goes to -1%:


However as it is only -1% it might very well be just controller, but in that profiler crosshair appears to be centered, I measured 66 pixels and crosshair being 33 pixels from both edges, but it's still bit hard to tell.

I just add 1% deadzone to deal with that, so it's not too big issue, but with OP's 7% that might be bit too much.
