Well as a DIY guy the current option works pretty good for me.
I mean I have 0 commercial input on my system.
I have mainly two ways to deal with my axes.
Try to set my limits within windows using stuff like dxtweak2, then I might use lfs axis limit to fine tweak in case of drift of whatever (imagine a min brake on 5%, a max gas of 97% whatever). When I use only a small range it is best to have a okeish behavior outside LFS.
Or put them directly in LFS.
I do like the idea to have full range shown, but I don´t know how to do it clean.
Currently I run a homemade direct drive wheel. Not much to do here it works fine directly. After 20 years I still don´t understand well the wheel turn compensation option, I don´t know it does not talk to me.
Gas pedal 5V from BMW my 0 - 100% are set in windows but it could work directly in LFS. Gives no issue.
Brake pedal, also from real car, wilwood stuff with sensor in milivolts plus preamp, this things is sensible to temperature, to bubbles in the system, well once I even adjusted during a race.
Clutch, currently unserviceable. But load cell in millivolts prone to drift and to pick up noise...
Handbrake hydraulic, can be set directly in LFS I don´t need precision and take margin for good on off effect...
Once I get home in can show my values but some are kind of wild.
