Logitech G29 Force Feedback Settings

I've been playing with the settings of the FFB and I can't seem to get it right for any scenario. I was wondering if anyone had found some nice set ups for either the Logitech G29 or the G920. I've had no issues at all setting up the H pattern shifter working with the clutch, which works tremendously I must add.

The only problem I seem to be having is getting both the steering and the throttle set up right. I think this may be something to do with the linearity but I'm unsure.

Can the throttle linearity be adjusted? I seem to have gone back to my early days of driving with either wheel spinning off the line or bogging down

To put it plainly does anybody have any preferred or recommended set ups for either across the board or for the different scenarios such as track racing, rock climbing, off roading, or general slow driving (cruising).
