Simucube 2 True Drive software feedback thread

So what number should we use in latest firmware?

Depends on what simulator you run. iRacing and AC should be quite happy with something around 12-15% and might get a bit worse in 20%. Rfactor2 seems to not be very happy at all with this filter, 0% seems to be best.

Mika, I can’t say that I’ve had any oscillation issues with AC for example and I always have the low latency filter switched off.

Would you think there would be anything for me to gain by using a setting of 12-15% or should that only be used if I was experiencing some kind of issue?

Nothing to gain in feeling wise using this filter.

But anyway, it helps those faster drivers who is at the top-end of the spectrum, where every bit counts. But your mileage may vary, latency on SC2 is already at very low levels, before using this LL Filter.

Hi Mika,
i´m very happy with the simucube 2 pro, but I have a question:

In iracing when I hit a curb hardly, then I often loose the usb connection of my simucube2.
Simucube switch off, because usb connection is lost.
When i reducing overall strength to 70% or something, it´s solved or better, but is this normal, safty mode
clipping ?

I´m a beginner, with a direct wheel…

Thanks for your support Dirk

Do you have both the power supplies connected?

“Ultra low latency mode”

Obviously the idea is a good one but i can’t help but think the allure of a setting called “Ultra Low latency mode” is going to encourage people to run it as high as they can where as it seems to be for the better for user experience that the name indicates its nature and behaviour better.

Was thinking something like “USB polling adjustment” or words to that effect to encourage people not to play until they understand that this is an application specific option. If they don’t know what it does its better that they don’t touch it until they do. I would also say a mouse over (i) would be warranted for this option :slight_smile:

Looking forward to September batch when im due to get mine :smiley:

Tim.

In next firmware version, there will be some more game titles presented in the template profiles via the Add Profile button. In case you definitively have some “killer” settings that should be included, please post that setting in the relevant thread.

We have added AC, ACC, AMS, ETS2/ATS and a credits field functionality so we can show your name/forum username as well.

I would recommend the tips that @Exact-Performance has given in regards to AC as being well worth a look at.

I think many of us have followed his guidance for this title have came away feeling very impressed.

Hi @Mika, i’m new here and curious about this platform.

i’m waiting for my Sc2 Ultimate from RaceWerk. You think that RW is a good/serious distributor ?. I’m completely new on Simucube/OSW. Anyway, i want to ask you some questions :).

  1. You know if an API Set (SDK) is provided for your Sc2 platform ?. On my spare time i want to write a little app for smartphones to control all settings via touch screen without continuosly switch windows or exits from sims “full screen” mode. I think that this can greatly help for fine tuning and better profiling.

  2. I don’t know if the problem was fixed but in case it’s not fixed, you think that ( for now ) i can mitigate the problem with USB bandwidth with a dedicated PCI-e card ?.

  3. Why Sims or ( true drive ) is not capable to dinamically change settings based on telemetry from simulators ?. Is not a good idea if parameters like Inertia, Friction, Gain, Damping, RECON and others can dinamically adjusted based on telemetry, steering angle/car inclination and be able to change all feeling in Realtime ?.
    you can call it (Drive Match) or something like that. Can be a premium unlockable features at around 59 / 99. Even a Db with all car manufacturers official specs ( like REAL power steering / Steering torque Nm can be matched ) can be a nice add or a section where users ( drivers / teams ) can fill this DB with their findings on real tracks and cars. This is the real advantages that your product have to offer. it’s not a g29… Granite Device says that your products are the Ultimate , says ( only good is enough ) and it’s strange that features like this is not present in your software.

  4. You think that a pedals with RJ12 connector can be converted to be used with your SC2 ( accessory port ) and obviously mapped as ANAlog inputs on True Drive ?.

that’s all for now :).

thank you.

Hey, i’ve watched your videos but honestly this is what high performance servos sounds like when you try to develop a good firmware to use it. If you go to a factory where servos like this is used… you can’t stay in for more than 3 minutes. I’m waiting for my SC2 Ultimate but i just know that it’s more than probable that i have ( at least ) the same exact noises you have with your Pro unit. Price don’t give you nothing about this things.

A little bit of Coil Wine or noises is absolutely normal , expecially with some settings. That a DD is dead silent ( it’s a legend ) if you don’t use a really safe settings.

Now that we have pretty much completed the hardware and initial software project, we can look into these things. Most likely your smartphone app would have to communicate with an application on the PC, and we would need to have an API to expose the current profile parameters on PC. It is exactly these things such as advanced API’s that we will look into next. Feel free to PM me some specifications so we can start to think what to do, and to maybe narrow the scope a bit. Perhaps the API will go through the True Drive software directly?

A dedicated USB card has solved the USB bandwidth issue always. Only some AsMedia and VIA USB3 chipset are confirmed to have issues. Also some HMD devices (VR glasses) hang up the USB bus while SteamVR starts, which makes the FFB effect initialization things not to get through to the device. But this affects also other devices (Thrustmaster etc).

We are looking at telemetry based FFB - a reader is already developed for one of the most popular simulators. The problem thus far has been that it takes a lot of time to interface with a simulators, and to generate relevant FFB signals based on telemetry. The simulators themselves do not have any realistic data on what the friction and damping felt at the steering column is, and that is the main limitation. But we are investigating some innovative ideas!

a pedal with RJ12 input does not really say what the signal is. The accessory port has 4 analog 0-5V inputs. If your pedals are load cell pedals, a separate load cell amp circuitry is required inbetween.

Hope this helps; I might amend the reply tomorrow :slight_smile:

I disagree, my Bodnar SS2 was practically silent where as the SC2 Ultimate makes a lot more noise. I’ve got used to it now but it shocked me at first as it’s noisier than either the Bodnar, Lenze OSW or Accuforce I’ve owned previously.

Argon, IONIx1 and Simucube with Mige on MMOS was quiet as long as you did not run the filter on low settings.
You could make it noisy and feel quite digital at certain settings. Some of the settings we played around with in the early days would vibrate the fillings out of your teeth!

The noise depends mainly on the aspect that how quickly you want the shaft to follow the reference signal. If loose control is acceptable, then low noises are possible, but the more quickly you want the servo to follow the reference signal, then more audible noises will be created. Assuming that electrical designs are of equal quality and has low signal path noise by its design, then, when you have low noise servo equipment, its overall control is tuned to be “loose”, not “tight”. Bad electrical designs can also induce noise from the motor.

Our principle is to have as tight control as possible but with acceptable sound characteristics from the device. We want to make as low noise equipment as possible but some characteristics are more important than sound especially the ffb feeling.

SS2 is known to “oversmooth” the signal quite a lot. That’ll definitely add to the characteristics of low noise.

Hello Mr. Mika, :).

for what i read here you are for sure a pretty clever technician/engineer. :wink:

Remote Control
For remote control over API i think on a little server from the Host App ( a little module integrated on True Drive and this is good because true drive have to be always on, right ?. I have to try binding some slider vith python and remote it to xcode SDK or Android IDE.

I think even without directly expose crucial API or write frameworks some binned sliders can be useful via true drive with the help of a little html/css based APP on smartphones.

Mixed FFB telemetry.
Ahh Mika, you say me things that i don’t know… :|… Really the telemetry from those SIMULATORS don’t give realtime value for this data??.. i’m shocked :|… what simulate this things ?. i have to learn about this.

Pedals
Excuse me, Mika. you are right :sweat_smile:

pedals kit like Fanatec v3 or v3 inverted etc and i perfectly know that this kits is not the best of the best but is not that bad and i think can be an advantages. i don’t know the diagram but i think is not to much complicated to reverse it.

Anyway, i have a lot… of ideas on how to dramatically improve and increase this things. This things have to evolve and this is possible only via software because i think the hardware is 4 times better than software.

I really hope… that my Ultimate Unit is shipped as promised from Racewerk but i’ve read about late september!!! instead ( in august ) as claimed from racewerk web store.

Sorry for my over modified ( first post ) :).

Hi Si-Po,

your unit is certainly one of the best out there but you have to understand that even Bodnar don’t expose you the entire story :). The settings you can play with that unit is “balanced and controlled” to be advances, yes, but ( safe ).

For Lenze, OSw, accuforce…
i’ve tryed all of this motors but, honestly, this new units for SC2’s is different for what i can read onm specs… the Ultimate is on another league… totally. the performance of this motors are spectacular. the only data that i don’t knwo why is not present is the official sustained torque level/decay ratio and rpm but other than that the specs are really impressive.

Really not sure what you’re trying to say, you realise I have an Ultimate?

I’ve had it for 2 months, there’s no doubt that it is significantly better than any of my past DD wheels my only complaint is that it’s noisier. However if a little extra noise is the price you have to pay for lower latency and higher fidelity then I’m okay with that.
