You can use it on both, Joe, it will transfer across and will need small adjustments, if any. I am using very similar settings on my monster SC2 AKM build, it works equally well on smaller and larger servos I’ve found…
But just my POV, it might be different for others…
Thanks Beano,
I picked up an SC2 pro v2 from a local guy recently. This time I get to drive my SC2!!

This is interesting!
Finally! Full dynamic range without injuries. But lets see how well it works first…
Yes, it’s very welcome, especially in iRacing where you usually had quite weak FFB most of the time which encouraged people to have highest max force in True Drive(25Nm for me) because setting it lower would also scale down weak forces. But on the other hand iRacing had the biggest FFB spikes on collisions so it was far from ideal solution.
Few sims have a solution for that where you can make force output not linear i.e. Assetto Corsa - Gain curve adjustment , AMS 1: low forces boost. And I use it in AMS.
I think someone already asked for adding Gain filter in True precisely because of the iRacing issue. It would be nice feature that other DD wheel software/drivers don’t have(I think) and would be useful in some games, where you’d want to have i.e. low forces boosted.
Other idea is to add a simple slider/filter in TD where you set clipping force - amount of force you want the driver to clip to(by default max force - no clipping), so that beyond that all forces will be clipped. This way you could have max force set to 25Nm or 32Nm so that low forces are strong enough, but in case of accidents(or any other events) the force will be clipped to given value( i.e. 15Nm).
Hello everyone, first of all, absolutely amazing knowledge sharing in this thread. I went to sleep 2AM in the morning cause I just couldn’t stop reading all the technical articles. Really thanks @bsohn for that…
Anyway, I hope I followed the guidance correctly here for setting up my F3 and I would really appreciate your feedback on my settings.
I tested F3 on Nurburgring, as it’s pretty well balanced track - variety of all corner speeds, variety of kerbs heights, big breaking zones, elevation changes… Pretty much perfect track for tweaking imo.
The auto feature recommended Max Force of 29Nm. To allow for spikes I added +3Nm to arrive at 32Nm. The steering heaviness personally felt best at about 0.4 ratio, so in TD I set my wheel strength of SC2Pro at 12.8Nm (12.8/32 = 0.4). I hope that I followed this guidance correctly.
I also played around wit all the other settings (RF, D, F, I,…) and the below is close to optimal settings for me. However, still one thing that bothers me is that the feel of oversteer is veeeery subtle and catching a slide is pretty hard. Like for example the left hander T2 is extremely hard to feel the limit of grip and mostly feels like ice.
Do you have any tips on how to be able to better predict oversteer and feel the grip limit? I know we are talking iceracing, but still I would be happy for every tip that I get.
Thank you very much for your tips and happy racing! 
Everything looks good… as far as the oversteer detection… After you have your wheel set-up and it doesn’t feel as if it is actually imparting handling effects (I.e snapping semi uncontrollably or feeling too heavy to steer the car) then the issues usually come with car set-up as changes.
That being said friction might be a little on the high side to allow for the lightness in the steering to be felt quickly when a car begins to oversteer. Inertia helps counter that a bit but normally only after the moment has happened… As well your Slew rate is set very low… This will limit how fast of a change you can feel in the weight of the wheel… While it smooths things out if there is a quick change in the weight of the wheel it will be mitigated by this setting this can also allow the car to get away from you as you no longer have the sharpness of the movement to tell your brain Wait the car is seeping out… Which is needed in the sim world to a degree as we don’t have the seat of pants feel that we have from a real car… This is also why some people do run toward more activity in the wheel.
Thank you for your tips @bsohn
I always used slew rate as a tool to mitigate sharp peaks in torque caused by going over aggresive kerbs. The value of 0.2 was recommended somewhere in this thread, so I went with it. Now I noticed that while it did the job of smoothing the sudden sharp changes in the feedback, it also caused a lot of detail to be lost along the way. So turning off the slew rate really helped to feel oversteer more.
However, with slew rate completely off I had to turn up Damping in order to mitigate the issue of torque spikes. But then again, I don’t want to overdampen my settings to make all of my inputs dull…So the question is - what is a good tradeoff in slew rate/damping?
Regarding Friction/Inertia - turned both settings down to 5, still really can’t objectively say whether it’s better and whether this resulted in better detail, need to understand correlation between these settings a bit more…I am still pretty new to do this
Thank you once again for your help.
What is your steering wheel?
Diameter, shape, wheight…
I learned the hard way that you need to match Servo Damping Friction and Inertia to your wheel.
Bigger wheel: -Damping, +Friction, -inertia
Lighter wheels: +Damping, -Friction, +inertia
-Damping never higher than 20% in any scenario
-Friction <5 in a 32cm 1.8kg Porsche wheel, <2 in a 28cm 1.4kg formula rim
-Inertia <3 in the Porsche wheel, <6 in the formula one.
Then, at Racing FFb options, put Wheel Force slider al 1nm and forget about It, just change TrueDrive Overall Forces and iRacing Max Force.
Another tip is to match incar steering with True Drive steering Range. Take an example with F3 car, It has 450° aprox ( dont remember) see that in box turning to the bumpstop. Match that steering Range in TrueDrive and recalibrate on iRacing ( or match the slider manually). This is useful in Cars with less than 540⁰
Ascher F-28. Definitely will try to match that as you say, thank you! Also will the steering range matching.
Then, at Racing FFb options, put Wheel Force slider al 1nm and forget about It, just change TrueDrive Overall Forces and iRacing Max Force.
Here I think already got the Specific Output sorted (~0.43) to my preference so I think is not relevant I think.
It is all a balancing act as such… The thing is to Not try to mitigate the spikes but focus on the other details coming through, you can then adjust the Slew Rate, Reconstruction Filter and TBW to help reduce the feel of those spikes. The reconstruction filter is the only one of these three that will tend NOT to mitigate the signal as TBW is a low pass filter and Slew Rate alters the torque deliver. The Recon filter however tries to smooth the signal to the drive system with minimal alteration to its intended amplitude.
Here are the settings that I use for every car I run I haven’t run the particular car that you are running much at all but the iRacing open wheelers tend to have very spiky feedback in general.
The Wheel Force Slider is irrelevant as long as your Max Force needed is above the number indicated. It is a protection for say you have a 30Nm wheel set to output 30Nm and “auto” says the car you are driving (i.e miata is 15Nm) if you had the wheel force at 1Nm it would change Max force to 15Nm but you are outputting on a 30Nm wheel which has just created an override of 2:1 so you would be getting twice the force you should through the wheel… however if you had the Wheel Strength slider set to 30Nm as the wheel is… “auto” would ONLY go as low as the wheel force or 30Nm even though the miata might have the ability to be lower without clipping… this 30Nm with a 30Nm wheelbase would be 1:!.
Just “put Wheel Force at 1Nm and forget about It” is a more simple explanation but yes, you are right, It would be a “problem” in a few scenarios
thank you the settings are very good. I only drive gte / gt3 cars and it drives very well. did you change anything at the app.ini at the ffb?
Yes I did all of the Normal app.ini changes. Though I think newer installs of iRacing already incorporate many of the changes… The Bumpstop angle Is one though that should be changed for sure to somewhere around 100 - 180 degrees.
Why I agree with most what you’re saying, I simply cannot see why Damping should never be higher in any scenario.
I am very often (mostly always) running mine on 25%, and I have a large akm65 servo, see a fr# posts up the page for a screenshot of my settings.
Damping 25%
Friction 20%
Inertia 18%
Low-latency 8-16%
I leave slew-rate default though due to my large servo with heaps of mechanical damping. But ffb feel/settings are mostly always different for each of us, there’s no hard and fast rule of ‘we must never use this’ or ‘you should use that’ type of scenario.
Yes, agreed, that are settings that will be obviously impacting to the dynamic range capability of the servo, not referring to those, but from a filtering perspective, almost anything goes, I have seen over the years. It’s just up to what a specific individual prefers
Sure, you are running your custom servos at 100% Overall force, but @yeree and I are running our servos at 15Nm Max generally.
One point I can’t understand in your setting is Friction and Inertia so High, why?
I bought a servo Drive to not deal with hardware Friction or too much inertia.
Did you tried any of the Fanatec Porsche FFb wheels? If I put your values on my SC2 Sport It will work like any of those Fanatec wheels, yes with 17Nm but sluggish and incapable of self-centering.
Never had an issue with centering here, but probably because my TD is running 100% and I adjust in-sim to my liking.
Even with those filters I am using, running the TD at full setting gives me really good dynamic range and fidelity, especially my servo is capable of 45NM. My only comment was to say that filters will be dependant on personal requirements, servo-size and torque, slew and few other factors.
Even on my real SC2 Ultimate I run similar settings to what I have shown above, because it is extremely powerful and very fast in response. For the Pro, I typically reduced the main-filters all-round by 5%, so I would imagine I would do the same again going to the Sport.
So I would say that your servo torque capability and things like slew and mechanical inertia will determine filtering levels to a larger degree, but, of course, so will personal preference.
I use servo D, F and I to equilibrate my steering wheels to a given Overall force, because is not the same a light formula rim that a round chubby one.
Any other filter I change is to achieve the best signal from the sim, It is like a 2 step setup for me.
