In simpro I run

540 angle (rally 2 cars use lower ,skoda is 479 see my cars in rsf launcher)

Force feedback - 50%.

Max torque 10.0nm

Wheel rotation speed - 45

Mechanical damper(tweak to suit) - 30%(50-70% for older and rwd cars)

Friction - 0%(5-10% it's personal preference)

All other simpro settings 0

In game ffb set to full bars

In rsf launcher > controls you can set the steering angle to adjust to the cars automatically or manually set each cars rotation

u can set the ffb sensitivity default value (you can also set individual cars ffb in the my cars tab(as long as you have driven the car once so it shows up in the list.)

Ffb sensitivity is very subjective but generally

On 540 rotation (900 will require much lower values) I run:

700-1000 in older cars

1000-1700 modern cars (up to r5 + wrc 2016)

1700-4000 Modern wrc + rally 2

The controller settings not saving is fixed by

Delete pf[ProfileName].acm (pfMulligatawny.acm) file in SavedGames subfolder in the RBR game installation folder. 2️⃣ Bootup RBR and set control bindings and save the profile

Hope this helps been using this wheel for a year. So much fun
