I have had the V1 for about two years now. Make sure you update SC4 to get the ACC plugin. Everybody uses different settings to get the feel they want. I've tried other people's settings and I don't end up using them because it doesn't feel right to me. I don't like a heavy FFB. I like to be able to feel what the tires are doing as best as I can get it.
I'm using 98 Gain and others at 0 in ACC.
In SC4, I'm using Default mode 45 Intensity, 6 Spring.7.06 Smoothing and 540 rotation.
Game FFB 98, Game FFB Smoothing 15.69, Friction 1.18, Dyn Osc Stationary 100, all others OFF.
This is a good guide from Accuforce to go by...I use it.
Thank you. It's all good now with the same settings I posted which are the one to use when in beta. It was sim commander not in sync with the hardware and it needed several reboots of windows to do the magic.
