Guide for G27 (and other wheels) configuration

[RasmusP]

February 2024 Update:
Please don't read this thread. I know Google will show it, but it's old and filled with partly wrong information from me.
Just use my LUT package instead:

-------------- Don't read this! --------------

Older edit: After almost everyone prefers the LUT-Configuration, I created a Lut-only Thread with all my LUTs attached in a zip-file in the Download-Area here at Racedepartment.

Original post:
Hello everyone,
I know there are a lot of settings and guides online for "the perfect settings" but after I spent about 30 hours searching and trying, I really found MY best settings.
They are a combination of different guides (but with the "GAMMA-option" in use) that I will name right now and first:

Really nice and complete Guide on Assetto Corsa Forum
Reddit Thread where my adventure began (and where I got the Link above)
FFB Deadzone Fix Logitech G27
Guide for LUT Generator (can't recommend it but helped me understanding)

EDIT: I thought the LUT was what gave me my perfect feeling BUT IT WAS THE TYPE=GAMMA, not a LUT so I rewrote that whole Guide:

EDIT2: I found out how to write a LUT yourself so I did it and the result is something similar to the gamma-setting BUT less compressed, smoother middle-transition and therefore BETTER! Here is the link to the post if you don't want to scroll down: LINK

TL: DR Lines:
1. Adjust InGame-settings and Profiler

2. Open the controls.ini:
you find this ini in: "C:\Users\%username%\Documents\Assetto Corsa\cfg\controls.ini"
set MIN_FF=0.04, CENTER_BOOST_GAIN=1.3, CENTER_BOOST_RANGE=0.001

3. open the assetto_corsa.ini:
you find this ini in: "%...%\SteamLibrary\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini"
set ENABLE_GYRO=1, DAMPER_MIN_LEVEL=0.0, DAMPER_GAIN=0.7

4. open the ff_post_process.ini
you find this ini in: "C:\Users\%username%\Documents\Assetto Corsa\cfg\ff_post_process.ini"
set VERSION=1, TYPE=GAMMA, ENABLED=1, VALUE=0.5, CURVE=%doesn't matter%

5. HAVE FUN

6. additional:
- Logitech Profiler:
- overall: 100
- spring: 0
- damper: 0
- untick center spring, NO combined pedals, 900° rotation, TICK "allow game to adjust settings"

- AC InGame:
- Gain: 50% [depends on your wheel but for my G27 it is 50%. 75-125% InCAR]
- Filter: 0
- Min Force: 4%
- kerb, road, slip: 0
- understeer: untick
- Steering Settings: gamma 1, filter 0, sensivity 0!!

For those who want a detailed guide:

After I read very very much about all seen and all hidden settings in Assetto Corsa, I tried everything out, but one of these things was always bothering me:

1. you have a huge dead zone
2. your wheel oszillates
3. deadzone ok but no smooth transition at center
4. just too much force

The solution for me was the GAMMA-setting in the ff_post_process.ini!
Combined with the dampening-setting, the Gyro-setting, the min_force and the Center_Boost!
Short version of what this settings do:
To get rid of the Deadzone you need to combine the very little center-boost with the min-force. But then you will have a little bump in the middle because they have a "hard cut" at zero-force.
If you enable the GAMMA-setting this hard-cut will be transformed into a curve, just like the FFB-Output from Assetto Corsa will get compressed to a curve where little forces are boosted and the high forces are lowered.
Here are a few pictures of that:

1. Wheelcheck Result:
2. How the AC-FFB has to be alternated:

3. All these settings combined:

So you get rid of the deadzone but don't get an oscillating wheel! [Plus you feel more details.]

The Settings in detail:
1. controls.ini:
you find this ini in: "C:\Users\%username%\Documents\Assetto Corsa\cfg\controls.ini"

- Filter=0: This should eliminate FFB-spikes but for me it seems like it just kills little details but does not really smoothes out! So let it on 0!

- MIN_FF=0: That means, that the "zero force" is still zero force, theoretically it's THE setting to get rid of the deadzone BUT I experienced, that you need to get up to 17% for the G27 and then don't have a deadzone anymore but case 2.: your wheel oscillates.
If you go down to about 12% you have case 3.: the deadzone is still there, but little. Problem: it doesn't feel nice... 0 Force in the Deadzone and then BAM, FORCE.
My thought about that:
The "MIN FORCE" doesn't have a "Curve" for the lowest force. It just does a hard cut which ends up in my experienced results. (See Picture above: 3. combined)

- CENTER_BOOST_GAIN: In the Guide "FFB Deadzone Fix for Logitech G27 1.2" this setting is used.
Explanation: If you imagine the Wheel, the FFB begins at a little bit right and left from the center-> "deadzone". That is because the force that IS THERE, IN THE CENTER, is too low for your wheel.
This setting BOOSTS the FFB in the RANGE of "CENTER_BOOST_RANGE"

- CENTER_BOOST_RANGE: as mentioned, this is the range of the boost that applies on the FFB FROM THE CENTER. Theoretically you just need to "Boost the deadzone away". But this does not work, I tried EVERYTHING!! (combined with GAMMA this transforms to a "curve"!)

I combined this 3 settings in every possibility but you have always ONE problem: the "center transition" as in "you steer from left to right" gets a BUMP in the middle, because of the boost.
I tried to lower the boost, widen the range, give a little more MIN_FORCE. But nope, you always gets this unrealistic "center-bump". (so you need the GAMMA!)

I have to give the author much credit, it is a really nice setting but it's just not enough for me.

2. assetto_corsa.ini
you find this ini in: "%...%\SteamLibrary\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini"

- FF_SKIP_STEPS=0: If set to 1, you get half of the FFB-Refresh-Rate. So if you have a decent hardware, go with 0! Some people get an error on servers because their CPU is too weak. Then go with 1. It doesn't make a HUGE difference, but the more FF-Inputs, the better, right?

- ENABLE_GYRO=1: Honestly, I don't understand this settings but it smoothens the wheel without taking away important informations!
If you read about that setting: It is for Direct Drive Wheels as the Logitech G27 (not belt drive like Thrustmaster for example) and interprets "the wheel as a Gyro on certain speeds".
If your wheel is a little bit "shaky" overall or oscillates: go with 1!

- DAMPER_MIN_LEVEL=0.0: This means, that the InGame dampening (a few versions ago there was a slider?!) is OFF, when the Engine says the damper to be zero. If you increase this settings, your dampening will ALWAYS BE ON, even if the engine does NOT give the input for it.

- DAMPER_GAIN=1.0: That is simple. If the engine gives the input to dampen the FFB-Signal, it is indeed dampened. For my G27 I like it on 0.7 but if your wheel feels a little "numb" you can lower or even deactivate it. I find my wheel too shaky when on 0.0!
Sidenote: ALWAYS USE THIS SETTINGS FOR DAMPENING, NOT THE LOGITECH PROFILER DAMPENING!!!


3. ff_post_process.ini
you find this ini in: "C:\Users\%username%\Documents\Assetto Corsa\cfg\ff_post_process.ini"

- Version=1: No idea, just leave it!

- TYPE=GAMMA: I don't know how it works exactly but it is THE setting that got me stunning! I drawed a Curve about how it feels for me and it makes sense but honestly: no idea...
Here is the picture:

- VALUE=0.5: Well in one guide the author tells you "it is on 1 at mine, no idea, just leave it" BUT IT IS IMPORTANT!
It determines how strong the FFB gets "compressed". So on 1.0 it does NOTHING, on 0.1 you feel absolutely no details, it's like ultra-power-steering.
For me about 0.5 is the optimum for having details but no deadzone.
THIS IS THE SETTING THAT ELIMINATES MY DEADZONE AND LET IT FEEL REAL!
What is important here: you have to lower the global FFB in order to have "normal forces". The lower the value, the lower your global FFB! If you put VALUE=0.1 and global FFB on 100% you get broken arms for sure...

- CURVE=%doesn't matter, not active%": Well this is just the settings to take the correct LUT. BUT: I don't use a LUT and I can't recommend it with the G27. Tried it and it was just awful!
IF you want to activate a LUT you have to change TYPE=LUT (thanks to Ross Garland for giving me that info!)


Conclusion:
I know that was a lot and I know it's not perfect but maybe it will help you with your settings and increase the fun you have with Assetto Corsa.
I switched over from Project Cars but was so mad with my wheel that I thought about buying another one. The Deadzone was so annoying but the graphics, sound and gameplay were better and I really wanted that game to get working!

This is just a wrap up from other people's posts and guides but I didn't find a guide here, where you don't need to login to the Assetto Corsa Forum or even there, where all these settings are packed up so you can just read it down and get your settings.
And most importantly: I nowhere found any mention of this GAMMA-setting in the ff_post_process.ini so alone for that setting I wrote that all down.

I made this post to give all searching souls another thing to try and hope this makes even a few people happy

Let me know if it helped you!

Kind Regards,
Rasmus

Holy cow, this looks like rocket science!!!

I plan to play AC in the future with my G27, not so sure anymore!

Maybe I have to come back to this for help, so my thanks in advance

 

[UMC 22]

Where did you get the info about the LUT? The reason I ask is because there is another guide here on RD somewhere which says you need to change TYPE in ff_post_process.ini to "LUT" in order for your custom LUT file to be used at all. Curious as to who is right and who is wrong.

 

[RasmusP]

... you need to change TYPE in ff_post_process.ini to "LUT" in order for your custom LUT file to be used at all...

Well I didn't try that to be honest. What could be: my lut get's "mixed" with something Else and therefore "gamma". I will try that out and tell you about my experience but what I don't get is what "post process" other than a LUT should be applied? Anyway: my LUT did a big change and feels really nice, so it works! How: I will report back!

Holy cow, this looks like rocket science!!!

You are welcome to ask then!
Yes, it's rocket sience (I study mechatronical eng. and figuring that all out and putting together felt like a whole semester haha).

But it is totally worth it! This feels real for the first time in any game! I can nothing but recommend that game

 

[RasmusP]

EDIT: after the few responses about the "TYPE=LUT" I rewrote that whole Guide so don't get confused

I switchted TYPE=LUT and VALUE=1.0 (in the ff_post_process.ini).
GOD it feels awful! HUGE deadzone and then way too strong FFB when it kicks in Oo
VALUE=0.5 is little bit better but still the same, just awful!

Then I deleted my LUT and it didn't change anything.
So I switched ENABLED to 0 and I had my old FFB back, which I don't like...

So I put ENABLED back to 1 and it was fine again.

Switched the GAMMA to 0.3 and oh boy, really strong FFB from the beginning but no details.

SOOOO I can delete my whole Guide because the LUT didn't do **** and it was just the GAMMA from ff_post_process->ENABLED=1 which simply compresses the FFB.

I don't know if I am happy that I now can tweak it to personal perfection or really mad...

Anyhow: THANK YOU for seeing my mistake and telling me about it! Shame on me, but I am just another noob who tries hard


Conclusion to the GAMMA:
if you put it too high you don't feel any details, it's like "super-servo". But if you let it on default the G27 feels unreal... Seeing how smooth the real pro-drivers are steering let me think that GAMMA=0.5 is way more realistic on the G27. You won't get so much details but you can drive really smooth and due to the smooth steering you really feel when the back wanna slip out!

 

[ronip]

I tried this settings and they are better then everything else i tired. very smooth, only thing not feeling right is: a little bit slow in response.

yeah that's right. I find the feeling when you drive tracks like the Nordschleife very nice because it's smooth and you really feel the grip but if you try to cut through tight corners left-right the wheel is way too slow.

If you want that to change: activate the "center spring" in the profiler till your wheel is fast enough.

OR: lower the damping setting in the assetto_corsa.ini! The lower, the faster but also a little bit less smooth.

 

[ronip]

will try, did you changed anything lately, i am driving your setup from the beginn of thread, only thing i didnt change is this last line with LUT. cos i dont have lut. there is still just a little feel about grip also in this setup but i think thats already a maximum of g25 wheel.

The entry post is my current setup, I didn't change anything! Car is set individual from 80-120%, also different on different tracks!
the LUT-line doesn't matter at all, because TYPE=GAMMA and not type=lut. I don't have a lut either

If you want overall stronger FFB just set the global force to your liking instead of my 50%.

I am open for further questions

 

[Piereligio Mods]

Very interesting, I'll try to follow this guide from the start to the end.
I think some of these things could be helped out by improving my mod (the one for the deadzone. It's basically a .bat file actually). It would be cool to start a cooperation about it.

Yes of course, take your time and give me Feedback when and if you want always happy if I can improve things further.
Problem with all that: I lose details.. But when I raise the Gamma I have to raise the min force or the boost gain. If I do that, the center get's less smooth. But I really need that smoothness to have a good turn in. It's a misery haha

UPDATE:
after getting caught up in a thread about the LUT I found out, that it is quiet simple to write a customized LUT yourself. So I tried it and after about 10 hours of work I got a LUT that feels even better than Gamma+Min_Force+Center_Boost.
I got way more details and the "bump" in the middle is completely gone!
Here is what I think my old settings look like in comparison to my LUT which I created with Excel+Diagram to see exactly what I am doing.
Old setting:

My LUT:

So you see: less compression of the forces and also a smoother transition to "zero force". No more bump in the middle and a very smooth and detailed FFB when turning in.

What you have to configure for using the LUT:

\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini:
ENABLE_GYRO=0 I like it off with the LUT
DAMPER_MIN_LEVEL=0.0 no dampening!
DAMPER_GAIN=0.0 no dampening!

\users\dokumente\Assetto Corsa\cfg:

controls.ini:
MIN_FF=0.00 the first line in the LUT 0|0.08 is the 8% min force!
CENTER_BOOST_GAIN=0.0 not needed!
CENTER_BOOST_RANGE=0.001 not needed!

ff_post_process.ini:
TYPE=LUT activates the LUT instead of GAMMA!
ENABLED=1 activates the use of the LUT/GAMMA
VALUE=1.0 with GAMMA this is how much you compress the FFB. With a LUT you want 1:1 processing because your LUT is already the compressed curve!
CURVE=YourLutName That must be the same name as your LUT-file!


And finally: here is what my LUT looks like: (yes, very long...)
[I updated my LUT so it gets a bit more "heavy" but I don't know if others like it. It's in the spoiler:]

So you see: less compression of the forces and also a smoother transition to "zero force". No more bump in the middle and a very smooth and detailed FFB when turning in.

What you have to configure for using the LUT:

\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini:
ENABLE_GYRO=0 I like it off with the LUT
DAMPER_MIN_LEVEL=0.0 no dampening!
DAMPER_GAIN=0.0 no dampening!

\users\dokumente\Assetto Corsa\cfg:

controls.ini:
MIN_FF=0.00 the first line in the LUT 0|0.08 is the 8% min force!
CENTER_BOOST_GAIN=0.0 not needed!
CENTER_BOOST_RANGE=0.001 not needed!

ff_post_process.ini:
TYPE=LUT activates the LUT instead of GAMMA!
ENABLED=1 activates the use of the LUT/GAMMA
VALUE=1.0 with GAMMA this is how much you compress the FFB. With a LUT you want 1:1 processing because your LUT is already the compressed curve!
CURVE=YourLutName That must be the same name as your LUT-file!

Very interesting, again. However using this way, won't the little bumps feel a bit more aggressive on the zones that aren't the center?

 

[RasmusP]

Yes and no. That's why I needed about 10h to figure it out. The curve in the beginning of the graph needs to fit the deadzone.
But I don't know exactly what you mean so I will just write some things about it!
The bigger the curved section gets, the more compressed will be the ffb. So yeah, if you do that to the extreme you will have 100 percent force everywhere, no details, much oscillation etc. But then you also need to lower the overall force. (See first Post, gamma = 0.5 - > overall force only 50 percent!)
I tweaked so long until the ffb felt really linear on the g27. So my curved section fits perfectly in the ffb Response of my wheel. It doesn't feel like a modified ffb but it feels firm around the Center and then get's heavier in a smooth, linear way.
If the curved section gets just a little bit bigger, you will have a strong turning in but then not much force coming afterwards on top of that. If the curved section gets too little, you will either get a deadzone or a light turn in but then too much force coming on top of that (bumps, curbs etc).

I hope that wasn't too confusing

That is actually the first usable FFB setting that isn't a terrible drift or a just outdated one since I bought the game in 2014. For some reason the minimum force has set itself to the maximum (I think it was 0.30 or 0.40) after I changed everything in the .ini files, which resulted in a way too heavy rattle in the center position. After turning it again to 0.04 and also setting curb and road effects to 10% it feels so natural and nice. All other settings I have tried so far felt either too loose or way too heavy. Thank you, I can finally enjoy AC.

I'm now just starting to try and get AC started with my VR-Headset, in the meantime could you please explain what to do with all those numbers you listed above? Tried the links in the first post, but didnt find the answer to my question - there's so much info around out there regarding FFB and AC, but I would like to stick to your settings, as they seem to be the most researched - is it just copy and paste your numbers in my crazy1.lut (the only .lut file I find in the cfg folder)

Thanks for your help and efforts - I hope I soon can enjoy your work live at my wheel - btw, does it make a huge difference if I dont use the original rim from the G27 - mine is now working with a SparcoP310, and it worked brilliantly in DirtRally so far.

For your .LUT for your wheel you could follow this guide, as those numbers might not suit your wheel, so generate your own plus using the settings posted here.

I will do it with numbers, don't interpret it as "hars tone" please
1. I am happy for everyone I can help finding his/her way to their perfect settings! Thank you!

2. the "magic lut mystery": You create a textfile and put in the numbers. Points for decimal numbers, "|" for "this number for that number".
So create a .txt, fill in the numbers and rename it to "blahblah.lut". 0.00|0.10 means "at zero ffb output from the game, send 10% force to the wheel". It's no magic Afterwar just go into theff_post_process.ini and rename "crazy1.lut" to "blahblah.lut". That's all

In my "updated post" with all those number there is a picture on top which is the graph to the numbers. X-Axis = "output from Assetto Corsa", Y-Axis = "Input to the wheel".

3. The rim should NOT matter in any way! The lut is for the ffb motor in the wheel base and needs to be "correct" (correct = suited to your feeling). What comes after the motor only makes a slight difference in how the "correct motor output" feels for you.

4. what the lut-generator does and why YOU don't need it: The little programm called "Wheelcheck" tests your wheel motor and creates a file where you get the "response curve" for your wheel. So you will see: 10% ffb output from the game/wheelcheck results in xx% ffb output from the wheel to you. Little bit complicated when seen first but you can see how the wheel motor reacts to ffb input. The problem here is that everyone seems to think "ok, so you need to create a lut that "corrects" the not perfect looking response curve. THAT IS FALSE! Because (in hard words) the Logitech G27 motor is pure ****! If you correct the response curve it just feels AWFUL!
So my lut does NOT correct this curve but alter it to what YOU GET FROM THE WHEEL feels good.
back to topic: wheelcheck creates a file of the wheel response curve.
The lut generator takes that file and creates a lut file. But a "corrected" lut file, which feels awful...

So don't use the generator, just create a .txt, fill in the numbers, rename it to "my_custom_lut1.lut" and you have the same as wheelcheck+lut generator, just suited for you

5. I got a pm which stated, that the Thrustmaster t300 does not work well with the lut but my guide calls for "and other wheels". Yes, but you need to read all explanations and alter my numbers for each wheel (all logitech G27 should be similar though).

6. If anyone wants a customized lut just pm me or write it down here. To help you I would need some analyzing from you like "I have a deadzone in the center" or "I don't feel any details" or "going straight is too light but driving over a bump shakes my whole wheel+arms" etc.

I am happy to help you

WoW - I just managed to drive a few laps in VR - oh man, it's just nuts!

FFB was as expected rubish, thanks for all this explanation above, will do it step for step and report back!

Yeah I need a VR-Headset too 27", 1080p, 60hz Monitor... Not really the same

Don't bother to ask if you don't get behind something. That was a LONG process for me to find and configure all these things and I am really into ini-files, motor-curves, diagrams etc. It's no shame at all to struggle with all those numbers and settings!
