Guide: Optimal FFB settings for rFactor 2 - The key to being in the "Zone" :D

Are you asking for confirmation that the FFB multiplier "in fact scales the NMST to within the available strength on the physical wheel."? If so, then yes and no. Yes in that it has the same affect as if you're simply increasing or decreasing the NMST/STC value. No in the sense that that's not how the calculations go about scaling the virtual steering torques to the physical wheel torques.

That's right. But there must be a defined limit that corresponds to the maximum torque output from our physical wheels.

Yeah, sounds like they just suffer from clipping out of the box with the default ffb multi of 1. This is quite normal (from memory). But i don't see a need to fix it with NMST. You just need to lower the ffb multiplier in game until you no longer experience clipping (using TechAde's plugin to help).

I think one of the main reasons that devs set the NMST lower than optimal to avoid clipping with the default ffb multi =1, is that most people still use older generation ffb wheels. These older wheels don't have a lot of torque which makes low end forces very difficult to feel/notice if at all. Decreasing the NMST naturally increases the strength of low end forces but at the cost of lowering the virtual steering wheel clipping threshold.

 

I hope I have found it.
.hdv file, controls section, NominalMaxSteeringTorque

e.g. BT20:
[CONTROLS]
NominalMaxSteeringTorque=13.2

 

So, is it worth setting STC option to an custom value? I mean, if a car has NMST lower than STC, than our STC value won't be realistic? If NMST is higher, then STC value also won't be realistic and it will be ignored.

So, is it best to ignore setting the STC value completely and just adjust it with FFB multiplier ingame?

Or, if the STC is important, can someone write the value for CSW V1 wheel?

 

Adjust the FFB Multi. The only point of using the STC to globally override the NMST setting is if you have a wheel with very large range. I'd say an Accuforce in 13 Nm mode (there's a 16 Nm mode) is just about the bare minimum to use STC. Then again, are there any cars that even have a NMST of under 13 Nm in the first place? Hmm...

 

from hdv file. Run MAS2.exe in ...\rFactor2\Support\Tools, choose "Open" and find desired vehicle folder at ...\rFactor2\Installed\Vehicles, choose the package to open (usually named ...car but not as a rule). Then find .hdv file and "Extract" it to desired location. Then open with notepad and look for the NominalMaxSteeringTorque as I have just done

PalatovD4 - there was NominalMaxSteeringTorque in upgrades.ini file

 

NMST is meaningless if you want to drive the car in 1:1. NMST is just a value stating "this virtual Nm value is what will equal 100% FFB output" (FFB multi @ 1.0 of course). it just a number someone decided on.

The only way to drive a car at 1:1 is if you have a wheel that can cover the entire range of forces that the particular car will ever output. I think you can check this through Motec from data going around the track. Or, you can set STC to match your wheel's power, and if this is more than the particular car's NMST then you will have 1:1 FFB until the virtual car goes over that STC value - if it goes over it - then you'll clip.


EDIT: I think I may have misunderstood you. If you want to know ever car's NMST in order to change it or to calculate the FFB multi which will = 100% output at your wheel's max torque (NMST × Multi = your wheels max torque) then I see what you're doing but the problem with that is many cars, in-fact the majority, will output forces higher than 13 Nm, therefore, driving every car @ 1:1 with a 13 Nm limit is going to introduce clipping quite early on.

 

As I already said, the Palatov has 11 Nm with rf2 steering and 7 Nm with rf1 steering. Have a look at the upgrades file.

 

hm, I have found 9 there...
anyway thanks for the advice, post edited.

 

download

Hi Dripper thx for your thread .

i downloaded the first link you mentioned , that went well also the test went well then i looked in my documents and i found the log file BUT how do i make this graphics from this logfile , is this easy to explain, i hope so
2nd yoy where talking about a second download but this one i cant find , so if you please can you put that download link once again.
Thanks very much

regards Peter

 

Hi Peter,

You want to plot a graph of the rightmost data column (y-axis) against the leftmost data column (x-axis) in excel or i can make it for you if you send me your .csv log file. If so, what wheel do you have and what settings in the profiler?

Here's the link to TechAde's plugin: http://isiforums.net/f/showthread.php/7546-rF2-Pedal-Overlay-Plugin

However if you are using the steam version of rf2, i don't think it will work based on the most recent post by TechAde.

 

FR3.5 2014 is 16Nm

 

thanks, updated. How did you find it, what is the source?

 

Wheel

Hi thx for replying

I am not using Steam for RF2 normal installation. Pedal overlay got it and works
I have the uploaded , hope its done well , the test was done in Iracing Settings on Profiler Mmos2014 Rotation 900 Overall Filte OFF Min Force 0.95% Max force 100% Damping 10 Frictio Filter 10 In iRacing Controler FFB enabled 5% Lineair selected Damping off .
I have a OSW settings in Mmos2014 for RF2 max force 29% Filter all 3 all rest default

Hope you can do something with my information if its given to you .

Regards Peter

 

Hi peter,

You've sent the file as a pdf and i'm having trouble coping over the array of numbers into excel without them all pasting into just a few cells.

Could you upload the original .csv file that wheelcheck.exe should be creating after performing a steplog2 test please? thx

 

Hi

I was just wondering if anyone here uses motec at all?

I've just noticed two new channels that are logged called "FFB Output" and "Steering Shaft Torque"
View attachment 18753
Would these two graphs help at all when setting up a wheel?

 

Sure, as you can see where FFB exceeds 100%, and torque values.

 

What about the bottom graph?

 

The "Steering Shaft Torque" is the net torque acting on the virtual steering shaft due to the sum of all forces acting on the cars two front tyres at each moment in time.

"FFB Output" is the resultant ffb output from rf2 telling our ffb wheels motor to produce some percentage of it's maximum torque.

What your graphs also show is that rf2's "FFB Output" is basically an exact copy of the "Steering Shaft Torques".

I think only in checking whether your chosen car-specific ffb multiplier is optimally set to avoid clipping in game. You can already do this whilst ingame with TechAde's pedal & ffb overlay plugin but you might find it easier to check afterwards with the motec logs.

 

Looking for some insight on where to get some understanding of Wheelcheck results on a G25? Any suggestions on where to ask appreciated.

Cheers

 

Run wheelcheck.exe and under spring force select "min force" test a few times. You will be given a percentage at the very bottom of the app use that as minimum force in rf2 ffb settings.
