Don't post random useless stuff please.
Here is my setup, jpg attached.
I modify the button control rate from 3.0 to 4.0 according to the car I use:
TBOs and LRF usually 3 to 3.5
FBM 4 or more if you want to be able to change gears
Low powered car 4 or more
Faster cars with more power and downforce 3 or less but still hard to control on/off, requires some tapping...
Tip: I separated the throttle and brake from the mouse and back on kb, that makes steering more stable.
Adjust brake strength, usually down a lot, and move the bias to prevent lockups.
You can get decent lap times with the mouse, it takes longer to get them because of the lack of feeling - check my stats, as mid-pack driver, and Palluka's stats for alien fast mouser.
I use a MX1000 laser mouse, excellent and I have had it for a few years with no issue - I can say control is probably as good as a non FFB wheel but the onoff keyboard "pedals" are the worst of things. Force yourself to use minimal steering input if you want speed and tyres that last.
LFS will become frustrating with a mouse, but you still have a few months ahead for this to happen. I need a wheel
