Hi mate,
could you describe what exactly you mean by "sensation of power steering enabled"?
I'm asking because AC has no power steering simulation at all. My LUT config doesn't change anything else apart from the first 20% of ffb being stronger (but in a smooth curve instead of just +15%) to get rid of the deadzone.
Power steering would mean a dynamic compression of steering forces.
When going from the G27 with my LUT to the CSW 2.5, which has no deadzone, everything felt the same, apart from being way stronger and allowing for more dynamic.
So my thoughts are that you mean 2 things by "sensation of power steering":
1. power steering cars are always very tight around the center because of the hydraulic pressure.
cars without power steering feel a bit weak around the center in city traffic.
2. the dynamic range is too low, which is a bit like power steering in real life
The thing is, though, that cars without power steering feel super tight on the Autobahn at higher speeds. And AC is only good at simulating driving quite fast. Everything below 60 kph is a bit "meh".
And the G27 simply has not enough torque to give the dynamic sensation of no-power-steering-cars
Quite a long explanation but if you want a bit less tightness around the center and a bit more dynamic range:
Go into your CSP settings (are you using custom shaders patch?), go into the ffb tweaks extention and enable the "Steering range compression".
This is ACTUALLY a dynamic compression of forces. Default is 100%.
300% is like modern power steering in road cars.
For you, 50-70% should achieve what you're searching for
