You'll want to modify these settings to suit your own taste, but I just posted them in another thread...  In FH5, go to settings>controls>wheel. Under "Custom Profile 1", save your steering axis, brakes, h-shifter or sequential shifter, clutch, handbrake, etc. You must also save a few things for activating ANNA etc. Then, go to advanced control, set vibration on, set deadzones to 0/100 for steering, throttle, brakes, etc. Set deadzone for e-brake at about 20/100. Leave game defaults for force feedback scale, etc. Under HUD and GAMEPLAY, set DATA OUT to ON. Set Data OUT IP to 127.0.0.1. Set Data OUT port to 10001. Exit game. Now, go to SC4: Launch game using SC4. Within SC4, my settings are Game Force Feedback OFF (Red circle around toggle switch), Game Force Feedback Smoothing OFF, Damping, Friction and Inertia at 1.18. Stationary Oscillation Control 100, Oscillation Control 100, Engine RPM 12.62, Steering Force Feedback Foundation 100, and Road Bumps 5. Under Device settings, I normally use about 650 degrees rotation but occasionally swap up to 900 degrees or down to 300 degrees for things like drifting. Set your intensity at whatever feels best. For me it is at about 60. If you have additional, non SC4, motion peripherals, then you can use SC4 to forward to a different Port operating those peripheral(s).

I personally suggest that in FH5, you opt for Simulation Steering, set ABS to OFF, Stability Control to OFF, Traction Control to OFF, and (assuming you have an h-shifter) that you set Shifting to Manual w/clutch.  And, NEVER ever expect a stock tune to drive like the real thing.  Finally, remember that a lot of the downloaded tunes rely on ABS, Stability Control, Traction Control and other built in controller helpers.  As a steering wheel user, you'll wanna be picky about the tunes you use.  Feel free to try mine.  I have only shared about 10 tunes but I have many more that we keep within the discord server to run against each other, or to set records.

In FH5, I am using the Accuforce Pro V2, Fanatec Clubsport Pedals v3, Fanatec Handbrake, Thrustmaster TH8a H-shifter, and a Next Level Racing Platform V2.  I already have over 20,000 miles driven in game (mostly tuning cars for myself and friends on Goliath and more recently running Rivals).  I am enjoying it immensely and I "blame" SimXperience and Mr. Villers for all of it!  TY again Mr. Villers!

Finally, feel free to add me in game:  FWYFLYER.  Likewise, you can private message me for our discord server.  This is an arcade racer so we don't expect perfect driving.  We just enjoy the banter and the friendly competition. 

There appears to be a bug in the controller input wheel setup in FH5.  When I first select the wheel tab in the controller input screen, nothing happens and no assignments can be selected or made.  I have to click out to the keyboard tab, select don't save and continue, then click back on the wheel tab and it will create "Profile 1" and show all inputs are unassigned.  You can then go through the usual assignment process.

It also appears FH5 will only detect up to 3, the first 3, USB devices.  I have several button boxes, wheel, shifter, pedals.  The device ordering in Windows 10 is a royal pain to manage.  I had to unplug the button boxes and then can map anything from device1, device2 or device3 as listed in the joy.cpl Game Controllers list.

I left the standard SC4 game force feedback and game force smoothing enable.  Turned on both oscillation items to 100%.  No steering foundation.  I turned down offroad effects in FH5 to 0.5 and everything is working well. 

Tons of low-key fun!
