High frequency noise

Hi, i just got the SC2 Pro, when it is turned on there is a constant high frequency noise coming from the motor, the noise kinda goes away/stutters when I move the wheel but as soon as I stop moving it’s constant again.

Anyone else ever had a similar issue?

I will PM you a test firmware that should solve this.

That fixed it, thank you… 30mins after i post on a sunday and i get a reply with firmware to test… thats support! Very happy i took simucube over all the other competitors.


@Mika; I just installed a new SC2 Pro - and also have high feq noise out of the motor. When I turn the wheel 90 degrees, it stops, whe I turn back to center the high freq noise is back. Can you help me with this please? I have SC software 2021.1, TrueDrive v 1.00.33 and servo drive firmware 10826.

Hi, I also have an annoying resonance noise (I think). No solution?
Also because I recently changed the DD family and between True Drives that if opened before the motor crashes, plus this noise, I was a bit disappointed and embittered for the moment. :frowning:
Thank you

I have the same sound when driving.

Same, brand new SC2 pro.

It’s kinda annoying, true. The bad part is that it wakes my missus as it travels through my Alu Rig and gets amplified on top.

Does anybody have a usable solution / workaround?

Are you using the latest FW already that supposedly has the fix for the noise? Other option is to use a FW from march/april that also had the original fix, or even an older one (2020.10?)

Currently using the 2021 September build. The checkbox in the settings make no difference for me.

The only thing that helps right now is turning up the recon filter to 10 and lower the amps to barely usable levels.

Might try downgrading a few firmwares, but I’d like to wait on the October build first.

We are working on the new Simucube 2 firmware release, which will add support for new wireless wheel module. But it is likely not ready this month.


Yeah my simucube makes a sound like a metal “Slinky” toy.
I’ve started calling mine the “Slinkycube
I do wish this was fixable, but it appears to be a byproduct of the hardware design.

I once saw a cutaway view of the simucube and it looked like the copper coils were wrapped around the unit, picture a slinky, but much smaller and longer, wrapped around the center axel a dozen times.

Most of the time, you don’t hear movement of the coils at all, it seems like you need a “Fast Reverse force event” to cause the slinky sound.

The easiest way to reproduce this is just to set a hard stop in true drive and, without any sims running just turn the wheel as fast as you can until it hits the stop - I hear the coils “Slinky” every time.
(Another way to reproduce is to load up your favorite go-kart sim, as they ALL seem to make this sound with every single turn of the wheel)

@Bernhard_Berger thanks for the tips on recon 10+lower amps I’ve also had good luck by turning the slew rate to the minimal setting - I wonder if some combination of recon and slew rate reduction might allow for higher force (amps) in your case.

Just curious, if you turn the recon filter to 10+ don’t you lose most of the FFB detail?

imho, it (at least with my sc2p) sounds more like a metal cable hitting a flagpole

Has anyone tried to move from an Aluminum mounting solution to a Steel/Wood based one? In my case the Aluminum frontmount and especially the aluminum extrusions really amplify the noise.

I then removed the SimLab front mount, took a 80x20 Aluminum extrusion, mounted the official SC2 mount on it and it was MUCH quieter. Still too loud for my wife not complaining at night, but way better.

I suspect with increasing the mass further (thinking about a 6mm - 10mm stainless steel mount and ridding myself of the aluminum on the rig alltogether) and additionally decoupling the SC2 from the mounting solution via some kind of damping solution it could become relatively silent.

There is another noise related post for a reference.

Seems to me that some units with otherwise same settings and mounts are just noisier than others.
May be Mika can shed some light on this.

If I had to guess I’d say while there might (or might not) be minor differences in noise it probably comes down to how they’re mounted.

And for full disclosure: I own a used/second hand SC2 and I have a very unlucky combination of a very light weight and minimalistic aluminum rig that’s additionally decoupled from the floor which helps resonant frequencies even more. In my constellation it’s mainly down to my construction. Yes, there is noise - but in my case it’s heavily amplified of my own making and I’m just looking for ways to get out of my situation.

If it’s just resonance of the mount, try to dampen it with something like Dynamat, that should remove buzzing/ringing effect.

What True Drive version are you running?
