Cheers Christian. This is probably useless info but I could not help having a poke about and found a reg entry for my wheel here I have settings ConstantForce, Sine, Spring, Damper, Inertia and Friction. A friend with a Fanatec Podium compated and had a load of extra entries for diff attributes like RampForce and Triangle wave and others. I duplicated these entries and with some tweaks to match my settings but still unique where it mattered, added to my registry. The moment I entered the car with these settings (and the FFB activates) the game crashes. This showed that this had an effect but I quickly got out my depth lol and all I managed to do was make the game crash. I had to manually tweak the key names, default RZ name and Attribute setting with educated guesses so probably cocked something up but seemed to be on to something so sharing just encase it helps. Sounds like you are well on it anyway and likely much more accurately than I Cheers.
