I’m having some problems with my new Simucube 2 Pro and hoping I can get some help from the community!
I am using a SimLab GT1 Pro and the Simucube is mounted to it using a P1X Pro Front Plate. I have checked all bolts on the rig, they all have washers and are tightened properly. The quick release mechanism on the Simucube wheel is also properly tightened. I’ve also tried my settings using the latest 5 firmware releases and although I noticed minor differences in wheel feel, the core problems laid out below remained.
For my TrueDrive settings, see the start of the first video linked below. The settings I refer to for each of the following games I have been testing on are referring to the in game settings rather than TrueDrive.
So, here are my problems:
Assetto Corsa: I set the FFB gain to about 50% and it feels good, fairly strong and snappy although at lower speeds there isn’t much feel at all which is odd. I do get some pretty crazy oscillations as well at speed if I let go of the wheel and it feels (and sounds) audibly grainy when I apply some force during turns. Overall, I am fairly happy, although I’d like to get rid of the grainy feel.
Assetto Corsa Competizione: I set the gain to 20%, dynamic damping is 100%, damping is 0% and road effects are 0% and it’s completely unplayable. The wheel is oscillating violently constantly when moving, even in a straight line at very slow speeds, and even worse when breaking and going over rumble strips. It vibrates so loud it shakes the entire house and rig. Interestingly, turning down the gain to 1% just “scales” down this effect, it still happens, just with much less force. I have tried hundreds of combinations of settings in the Simucube app, and nothing fully gets rid of it. The best I’ve managed is Recon of 10, and turning down gain to 4nm, but that just feels pathetic and the vibrating still is pretty bad… This is like absolutely woeful, I’ve tried all the in game settings and none of them seem to make the slightest bit of difference. Surely there are lots of people running Simucubes in ACC that don’t have this problem?
Asseto Corsa Evo: Fairly good out of the box experience, feels a bit mushy and I’m not too clear what all the in game FFB settings actually do, but I’ve got it to a fairly similar level of acceptability as for Assetto Corsa; it has some grainy-ness but I can live with it. Going over rumble strips is causing some loud vibrations which caused me to dial back the gain more than I would have liked to fix it though, I’d like the gain to be about 50% but if I do this the vibrations are too loud, so I had to dial it back to 40%… kinda sucks. For an example of what I mean when I say “vibrations”, see the videos below which are taken from ACC.
Here is a video showing all my settings in TrueDrive, ACC settings and the vibration problem:
And this shows what happens if I turn the gain in ACC all the way down to 1%, it still vibrates like crazy (i.e. the vibration frequency remains unchanged) but it just quieter (i.e. the amplitude is lower), although honestly, not much quieter which I do find quite odd given 1% gain should really be resulting in barely any wheel movement at all, right??? It almost feels as if something is borked in the hardware and is resulting in overpowered torque changes… I dunno though, just pure speculation.
I get the same problem in iRacing too, no matter how much I tweak the gain, it just scales up or down this vibrating madness. Something seems wrong, right?
I am pretty sure there is something wrong with my unit… obviously I’m not expert, but surely no one can tell me what is seen in these videos is to be expected from the Simucube?
As mentioned before, I have tried tweaking the TrueDrive settings which would in theory remove this crazy vibration; namely recon, dampening, friction and inertia and although it improves marginally, it doesn’t go away. The only thing that really makes it mostly go away is reducing the force to silly numbers like 4nm, and even then the oscillations/vibrations remain they are just much quieter.
Something “feels” or “seems” wrong with this unit.
