You can install the base and then reset the center to any rotation you want or need.
Have you tried googling for settings? Anyway I would start from iRacing forums, or other general simracing communities, discord servers etc. Or even here where there is many profiles shared in iRacing specific threads.
Best way would be to figuring out how the settings affect the forces and start tweaking the wheel for your liking.
Many thanks for the answer.
The profiles I have are all very good. The only problem is that when I drive into a curve, effects such as bumps on the road disappear.
Edit:
Try activating “Torque Clipping Notifications” on TD Hardware settings and if you hear a BEEP BEEP then the Game are sending 100% constant force to SC2 and the Signal is clipping, lset a lower value on ingame FFb
With your help I was able to solve the problem. I actually overlooked the fact that the torque was not activated. I had normal FFB and therefore I hadn’t looked at it at all. Now everything works and I’m happy again
Let’s see if I notice a difference between the Pro and the Ultimate.
