How To Set Up G920 For Assetto Corsa

Assetto Corsa is all-time played with a force feedback wheel. As entry-level options, the Logitech G29 and G920 are fantastic, only the experience can be improved quite a bit by calibrating the wheel'south force feedback response. When you are trying to drive at the limit of grip, every little bit of information transmitted through the wheel is of import.

The motors in these wheels don't provide a linear response curve and accept quite a big dead zone where light forces just won't be felt at all. Calibrating your cycle goes a long style toward fixing both of these issues.

In this guide, I will show you how easy it is to calibrate your bike and amend the driving experience on these cheaper wheels.

Downloads

You will need two programs to calibrate your wheel. First, download the WheelCheck app. This actually tests your wheel response.

Adjacent, download LUT Generator for Air-conditioning. You lot will need to sign upwards for a free business relationship on Race Department to download this. On the Register page, whorl all the manner downward to the bottom to create a free account. This converts the information from WheelCheck into a file that Assetto Corsa can use.

Finally, download and install the in-game app FFBClip using the instructions on that page.

Calibration

Wheel Bank check

Wheel Check Settings — Bicycle Check Settings

Wheel Bank check is a tool from iRacing used to calibrate your individual wheel. It'south a very simple procedure:

Run WheelCheck.
Set the Max Count to 100.
In Spring Forcefulness, select "Step Log 2 (linear strength test)". This starts the calibration process.

Your bike will start moving in increasingly larger motions. Don't bear upon the wheel during this process! This process compares the corporeality of force the computer sends to the wheel to how much the bicycle actually moves.

Once it finishes, it creates a file called something like "log2 2022-04-25 ten-00-02.csv" in your Documents folder. We volition give this file to LUTGenerator in the next step.

LUT Generator

Run LUTGenerator and open the csv file that was just created by WheelCheck. This volition create a Await Upwardly Table (lut) file that Assetto Corsa can employ to control the force feedback.

Save this file in Documents\Assetto Corsa\cfg every bit myLut.lut. When information technology finishes, it displays a graph that shows the raw data in ruddy and the new curve in light-green. You tin conspicuously see what a huge difference this will brand. In my case, it is going to increment the forces at the low end and lower them in the heart to create an even force feedback response across the whole spectrum.

Assetto Corsa

To make Assetto Corsa use this file, open the Documents\Assetto Corsa\cfg\ff_post_process.ini file in Notepad and paste in the following text:

            [HEADER] VERSION=ane TYPE=LUT ENABLED=1  [GAMMA] VALUE=1  [LUT] Curve=myLut.lut

Content Manager

If you are using Content Manager instead of the default Assetto Corsa launcher, you no longer have to modify the ff_post_process.ini file. In Content Manager, go to Settings > Assetto Corsa > Controls > Force Feedback. Make sure "Enable FFB post-processing" is checked, and then set the Mode to LUT and choose the myLut.lut file.

I recommend saving these settings every bit a preset, every bit I take had Assetto Corsa forget all the wheel bindings for no apparent reason in the past.

Wheel Settings

Now that the force feedback response has been calibrated, allow'southward look at the available force feedback settings.

In Thou HUB:

Setting	Value
Operating Range	900°
Sensitivity	fifty
Centering Jump	Off

In Assetto Corsa:

Steering Settings

Setting	Value
Gamma	1.00
Filter	0.00
Speed Sensitivity	0.00

Force Feedback Settings

Setting	Value
Gain	100%
Filter	0%
Minimum Force	0%
Kerb Event	60%
Road Outcome	23%
Sideslip Consequence	0%
ABS Effect	25%
Enhanced Understeer Effect	Disabled
Half FFB Update Charge per unit	Disabled

Proceeds is the overall strength of all forces. Go out this at 100%. The FFBClip app volition adjust the gain automatically as you drive.

Filter smooths out spikes in the force feedback. I don't find this necessary on these wheels.

Minimum Force raises the lightest forces to a level where they can be felt on these lower-finish wheels. The LUT does this implicitly, so exit this at 0%.

Kerb Effect is the vibration felt when running over kerbs. I like to feel when I hit the kerbs, so I set this fairly stiff.

Road Effect is the vibration felt based on the road surface. This can get annoying if set too high.

Slip Effect vibrates the wheel when y'all lose traction. I observe this more distracting than anything, so I turn information technology off completely.

ABS Outcome vibrates the wheel when ABS engages.

Enhanced Understeer Consequence lightens the cycle to a higher degree during understeer. This feels unnatural to me, so I plow it off.

Half FFB Update Rate causes the Forcefulness Feedback calculations to run on every other frame. This could help your frame charge per unit on older computers.

The Kerb, Route, Slip, ABS and Understeer furnishings are personal preference. They are designed to requite you lot feedback most the motorcar just are non things you would really feel through a steering wheel.

FFB Clip

If you haven't already, download and install the in-game app FFBClip using the instructions on that page.

To get the almost data from the wheel equally possible, you want to make certain the game never sends more than ability to the wheel than it is capable of handling. This is called clipping. In the previous step, we set the Strength Feedback Gain to 100%. Left as is, the forces would clip constantly, making the wheel feel terrible.

The FFBClip app automatically adjusts the proceeds level as y'all drive to maximize the forces and prevent clipping. During your showtime lap or two, you will detect the strength feedback change as information technology finds the best setting. Arrange the FFBClip forcefulness setting to your preference for a lighter or heavier feel.

The Dynamic Fashion in the app maximizes the forces at all times. This raises the forcefulness feedback gain on the straights when forces are very light and lowers information technology in a corner when the forces are very high. I find this more distracting than helpful. You should attempt turning it on and off to see which yous prefer.

What is all of this doing?

Strength feedback is handled very much like an audio system. The louder the signal, the harder the wheel will turn. The game calculates the forces assuming that the bicycle tin "play dorsum" the exact bespeak it gets, very much like a speaker. Very expensive direct drive wheels tin can exercise exactly that, letting you feel all the tiny niggling details that get lost on lesser equipment. Cheaper wheels have a very poor ability to accurately reproduce the point, much like cheap speakers with very poor bass response.

When you lot calibrate the wheel and create the LUT file, you have a measurement of how the cycle really responds to the signals it gets. In this mode, the LUT acts like an equalizer on a stereo. Using the LUT, Assetto Corsa can adjust the signal levels sent to the wheel to get in movement the intended amount. It'due south a pretty clever solution to improve the feedback on cheaper wheels.

Continuing with the audio analogy, the FFBClip app with Dynamic Fashion on is acting every bit a dynamic range compressor. It raises the serenity parts and lowers the louder parts to overcome the inherent limitations of these weaker wheels. With Dynamic Style turned off, it is simply lowering the overall "volume" until the forces never prune, even when they are at their "loudest."

FFBClip isn't directly related to the LUT; you tin can use either 1 without the other, as they operate at different points in the calculation of the final force that is sent to the cycle. When used together, they provide a lot more useful data that yous can actually feel through the wheel.

Conclusion

The first time I set this up, I couldn't believe how much better the wheel felt. You lot'll get a better feel for what the car is doing and, as such, may find it easier to catch slides and improve your lap times.

Let me know if you lot have any questions or comments.
