SimuCube2 Pro - vibration issue

Hi Experts,

I just received SimuCube2 Pro from the dealer, and replaced my Fanatec CSWv2 with the SC2Pro. It physically mounted well and securely, also Fanatec wheel mounted well with the conversion kit, however, am experiencing a vibration issue when I playing iRacing.

The steering wheel vibrates strongly even when the car is not running or running straight. This occur even when the ignition is turned off on iRacing and the engine is stopped.

  • Frimware version: 1.0.33
  • True Drive version: 2021.1
  • True Drive setting: Read-only safe profile

Is this a hardware problem? Are there any settings I should check?

iRacing setting:

Let’s start simple: Move the iRacing wheel force slider to 25NM, then move the Max force slider to 25nm.

Similarly, also move damping and min force both to zero. Try never to use those two settings in iRacing, they are not meant for dd wheels.

Let’s go from there.


Hi @phillip.vanrensburg
I appreciate your advice.

I applied those settings to iRacing, and the vibration is disappeared.

I also tried to change True Drive setting from safe profile to the preconfigured iRacing profile. This worked well too, but I found that clipping occurred frequently because the Strength was limited to 9.3Nm on SimCube side. So, I changed the Strength to 15Nm and 25Nm, and the vibration happened again :weary:

My biggest question here is why the vibration occurs even when the engine is stopped and the car is not running.

Something is loose in your QR or the wheel, or in the mounting of the Simucube wheelbase.

Hi @Mika

I just double-checked that the mount, QR and wheel are securely tightened

The vibration is occurring even when the QR has removed (engine stopped on iRacing)

You’re going around things the wrong way. Create a new profile in your True Drive and set the torque there higher, maybe 15-16nm.

Set iRacing then on max-force to perhaps 35-40nm level.

After that, we can set some tuning filters in true-drive to remove vibrations and oscillatory behaviour, it will need some tuning with iRacing open-wheelers to get everything happy and working as it should.

Also, like Mika says, check if your coupler in the servo is tight. I suspect though a lot of that noise is coming from your rig rattling…

PS: Is your car turned off in the video just above, or is it idling in the garage?

It is turned off. In the last video, the engine is not running.

Are you sure the damping is at 0%?
Can you show us the Force Feedback section of you app.ini?

Yep, it sure seems to be the case that something is feeding a signal to his servo. Simple to test, just exit iRacing and leave True-Drive open, see if it does the same.

There he can play with desktop spring etc to test very basics…but it is definitely a tuning-issue with some stuff from iRacing ffb section in ini file causing problems. Best to start with a fresh file.

@Mika @phillip.vanrensburg

I found that if I set Damping at 50% in True Drive, no vibration occurs.

If I set it at 35%, the vibration starts when I off my hand from the wheel in a straight line.
At 0%, the vibration occurs regardless the car is running, idling or engine is off.

What could be the possible cause in this case?
I am thinking that maybe it is the lack of stiffness due to using SC2 QR and Fanatec QR(with Conversion Kit) at the same time. It seems tight enough though…

It’s 0%. Here is my app.ini setting.

had the same problem. This worked for me. Thx
