RasmusP's LUT Guide for G27/29 and DFGT 1.1

My custom LUTs for the Logitech G27, G29 and Driving Force GT

  1. RasmusP
    Hi!
    After my G27 Guide seems to help a LOT of drivers to finally get satisfied with their Logitech wheel in Assetto Corsa but most of them preferring my LUT-Configuration, I decided to create a little Guide only with the LUT-Configuration.
    Easy, simple, quick :)

    Here is the Link to the full Guide with all the different settings explained etc.:
    http://www.racedepartment.com/threads/guide-for-g27-and-other-wheels-configuration.134490/

    Now for the LUT-Configuration: (I will just provide MY favorite settings with *4 LUTs for G25/G27/G29 and 1 for the DFGT. If you want to customize them, please read and ask in the guide-thread linked above :) )

    Important: the first two values are the most important ones to get rid of the deadzone. If your wheel is shaking when standing still or vibrating too much:
    Lower the first value (0|0.120) to maybe 0|0.100. This first value is NOT influenced by the overall ffb from the game! The game ffb starts at the second value!
    Hope this helps :)


    1. Adjust InGame-settings and Profiler (ignore the NOT 900°... It's just to match the rotation of the real and visual wheel)
    AC_InGame_Settings.JPG AC_InGame_Settings_degrees.JPG Profiler.JPG

    2. Open the controls.ini:
    you find this ini in: "C:\Users\%username%\Documents\Assetto Corsa\cfg\controls.ini"
    set MIN_FF=0.00, CENTER_BOOST_GAIN=0.0, CENTER_BOOST_RANGE=0.1 (range doesn't matter if gain=0.0)

    3.
    open the assetto_corsa.ini:
    you find this ini in: "%...%\SteamLibrary\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini"
    set ENABLE_GYRO=0, DAMPER_MIN_LEVEL=0.0, DAMPER_GAIN=0.0
    assetto_corsaINI.JPG

    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=LUT, ENABLED=1, VALUE=1.0, Curve=%nameOfYourLutFile%

    This enables the LUT. If the Value is NOT 1.0 the LUT won't work as it should!

    5.
    put the LUT into the same folder as the ff_post_process.ini!
    ["C:\Users\%username%\Documents\Assetto Corsa\cfg\"

    5. HAVE FUN

    6. additional:
    - Logitech Profiler:
    - overall: 100 (don't raise this! you will get crazy rattling!)
    - spring: 0 (doesn't do anything in AC)
    - damper: 0 (only active while standing still or rolling slowly)
    - untick center spring, NO combined pedals, 900° rotation, TICK "allow game to adjust settings"

    - AC InGame: [updated values!]
    - Gain: 100% (75-125% In the CAR) [50% with the "recommended" LUT]
    - Filter:
    0
    - Min Force: 0%
    - kerb: 1-5% (unnecessary vibrations)
    - road: 2-10% (5% is enough to give you some subtle vibrations on surface changes)
    - slip: 23% (important to feel spinning or locking wheels!)
    - abs: 23%
    - understeer: untick (unrealistic, only good for learning)
    - Steering Settings: gamma 1, filter 0, sensivity 0!!

    [Assetto_corsa.ini:]
    - 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.
    The G27 delivers already very few details so you don't want anything to be dampened!

    - DAMPER_GAIN=0.0: I don't like it! It's only active when standing still or slow rolling but it sounds awful with the Logitech wheels and is just annoying in my opinion.

    Here are my LUTs :)
    They are all in the attached zip-file!
    I'm using the "recommended, no clip but stronger" LUT. It vibrates a little even when standing still but that's the price for the smoothest and tightest feeling with the G27!
    BUT you will have to lower the "Gain" in the Advanced section of the wheel options to 50%!

      Thanks for making me smile today! :)
      I thought about deleting the guide thread as I think the settings are not as smooth and nicely shaped but I thought some people probably like it anyway as the LUTs are a bit lighter and rather "fluffy" in comparison.
      Glad that you're having fun with it and I could help :)

    this is simply AWESOME! i use the recommended one but with 80% ingame ffb, a complete game changer!!! looks a got myself a new wheel!

      Hehe, thanks for calling it AWESOME (there's a German poetry slam video where AWESOME is the most used word, lol).
      80% seems a bit much but as long as it feels good for you, I'm happy that you're having fun :)

      Thanks! :) it's astonishing how much difference a little change around the center can do. And it's sad how little the devs care for it. Every game could easily implement such a feature and get a preset for all logitech wheels...

      Hi, thanks for still giving me these stars :)
      You seem to have the same problem as Kozzion (rating below yourself). Please write in the support area of this download so we can solve it :)

    Hello, thank you for your hard work! I am a complete noob in the simracing scene and am using a logitech G27.
    I did all the instructions you wrote and everything runs smooth!
    What I do "miss" is that my steer does not give any Force feedback? it doesnt shake while hitting kerbs or feels any resistance when I steer into corners and such?
    Is this as intended ? Or did I do something wrong ?
    1. RasmusP
      Author's Response
      First, thanks for still giving me 5 stars although you don't have any force feedback. :)
      Second: please let's solve this problem in the support area where we can talk better. I'll make a post :)

    Excellent application FOR MY G27 !!!but why put 900 degrees? I usually drive cars that have a 360 degree angle of rotation how should I do? Ah you a setting for that because I want a stop?
    1. RasmusP
      Author's Response
      Hi, thanks for the stars :)
      Assetto corsa uses the correct degrees for each car, as long as the logitech panel and the ingame degrees are the same. So what you are using is hardware lock, what you'd need would be to activate the "softlock".
      But the ac softlock is pretty bad sadly...
      For some reason though, the force feedback gets amplified when using less rotation. So going from 900 to 450 will boost (and clip) the force feedback.
      I would recommend that yoh just use this LUT like you do now and if the wheel shakes on straights, simply use numpad minus until the ffb is low enough to not shake anymore :)
      Or you use 900 and activate the softlock.
      Either in content manager or:
      \Steam\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini
      Then at the bottom- [SOFT_LOCK] ENABLED=1

    Wow, I have to be honest I was skeptical at first, I didn't think this could improve the FFB that much but I only needed to race half a lap to realize what a game-changer it is. Using G29 and AC feels awesome now, racing feels so much more immersive now! Thanks a lot for your work!
    1. RasmusP
      Author's Response
      Thanks for taking the time to write this nice message :)
      Occasionally I went back to without a LUT and indeed, massive difference although it's really just a little curve for the few first percent of ffb output!
      I wish you great fun with AC!

    What can I say? This LUT guide has totally transformed AC for me, to the point it almost feels a different sim now. I grew fond of rF2 and AMS for their superior FFB to the point of almost putting AC aside.

    This custom LUT not only fixes the dreaded dead zone in a much better way than the minimum force setting but crucially it unleashes much more finer grained detail on the FFB when playing AC with my G29 wheel now.

    IMHO every Logitech owner would have a better AC experience if this could be integrated officially into AC as a default profile for their wheels.

    Meh. Didn't fell like a huge improvement from my previous settings. I'm using a G29. The wheel now feels dead when driving on a straight line, theres no feedback whatsoever from the road bumps, and theres no resistance to turn the wheel when the car is stopped. Also it feels extremely light when driving racecars, which I don't like. It was easier to tell where was the threshold of grip on road cars. But I preferred my old settings so I'll revert back.

      Author's Response
      If you like, make a post in the support area. It reads like there was something not quite right with your settings. I created this to give me a tight and alive feel at the center. So the opposite of what you're reporting.
      The lack of resistance while standing still doesn't come from the lut. Just raise the "damper" slider in the logitech panel and put "damper gain" back up to whatever you like :)

      Hehe, after you stopped posting I wondered if you were just back to default settings.
      Glad you gave it a try again and this time with success! :)
      Your words are enough for me to make me feel these threads were and are worth the time I've spent noting everything down. The settings are done for my own pleasure. Nothing to thank me for them :p

    Feels almost as a real car wheel, at least as close as it can be with a wheel like that.
