IRacing settings v firmware settings.
-
Hello folks,
i’ve just become the proud owner of a Sim-plicity SW20 v3. I’ve attached a Thrustmaster Rally wheel via the Simracingcoach QR adapter. I have to say it’s all great kit and fitting was simple.
It’s an upgrade from a loaned Thrustmaster TX Leather (also a decent entry level wheel).l
I predominately drive the L49 but participate in SRF, GT and Porsche cup.
Knowing little about DD, Once fitted I tried the L49 on the “factory” settings. I went around Road America and used the Auto button. Boy was it heavy. It did feel like I was driving a weighty car on rubber tyres. I couldn’t over turn at a corner because I could feel the grip. Sadly I’m incapacitated and may not be able to use it for the next 6 weeks. So I’ve been doing some research.
I’ve found these excellent resources :
They are in the order I discovered them

iRacing FFB Settings and Analysis
https://svappslab.com/iRacing/FFBAnalysis
a graphical tool for analyzing the iRacing simulator FFB clipping point for your DD direct-drive wheelbase

So to my workings on the above chart the L49 at 31Nm telemetry, With the wheel set at 20NM. To get a “gentle” specific output of 0.333 I would set the iRacing maximum force setting to 58Nm.What I don’t understand is the relationship between “weight” in the firmware and “iRacing max force settings”. I’m assuming they do the same thing and having weight at 1 would be the right way?

"Weight" is a calculated force that acts against movement of the wheel in any direction. It seeks to simulate the masses that would exist in the steering system of a real-world car. Consequently the optimal value will differ from car to car. Ideally, you want just enough "Weight" applied that you can steer with a fingertip down a long straight but not so much that you can hands-off completely.
"Torque" is the value you adjust in concert with iRacing's Force settings and ideally should not be set at values that cause over-exertion.
In iRacing (or any other sim), the "Telemetry" tab is your friend for identifying clipping. FFB sessions in excess of 60 seconds are displayed in real-time with the last 4 sessions stored as historical data.
The basic principle is to run a representative lap with "Torque" set to a comfortable level. 8-10Nm is a good starting point. Use the auto setting in iRacing to get into the Max Force ballpark and run another representative lap.
Check the "Telemetry" tab for clipping in the current session. If your clipping % is higher than 0.00%, raise the Nm value to reduce the gain from the sim and raise the "Torque" value to compensate.
Ensure the FFB session is ended by disabling FFB within iRacing then re-enabling it.
Iteratively run representative laps till "Telemetry" shows 0.00% clipping
Adjust the "Weight" if required to reflect the current settings
Finally switch to the "Settings" tab and reduce the "Controller Mode" iteratively until you feel no additional benefit (the lower your "Weight" values, the lower you can run Mode values without motor noise).
