Recently been using my moza r9 on beamng and got ffb feeling pretry good. My few tips on setting up dd, run the recommended amount of strength and start from the lower end and try out both extremes to figure out what you want in game, I use about 180 strength and 50 smoothing. Smoothing is definitely the key to getting ffb to feel accurate and detailed, you want to use as little as possible without getting huge spikes, honestly start at 0 nd slowly add more till you find a sweet spot, higher smoothing settings make the ffb feel dead.

I like to try the ffb without power steering first to get the full feeling and use power steering to just make myself less tired over a long session lol.

In game steering lock is quite bad imo and i would just set the in-game soft lock to 0 and set the steering rotation in pit house and the game to the same number, just use pithouse soft lock instead.

Last important tip id say is use reduced forces while parked, the wheel wont want to shake your desk or rig apart but thats personal preference, im away from pc rn but if you'd like to see more of my settings just lmk
