RasmusP's LUT Guide for G27/29 and DFGT 1.0

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 3 LUTs for 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
    - spring: 0
    - damper: 0
    - untick center spring, NO combined pedals, 900° rotation, TICK "allow game to adjust settings"

    - AC InGame:
    - Gain: 100% (75-125% In the CAR)
    - Filter: 0
    - Min Force: 0%
    - kerb: 0% (unnecessary vibrations)
    - road: 1% (1% is enough to give you some subtle vibrations on surface changes)
    - slip: 4% (important to feel spinning or locking wheels!)
    - 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.

    - DAMPER_GAIN=0.0: I don't like it! The G27 delivers already very few details so you don't want anything to be dampened!

    Here are my LUTs :)
    They are all in the attached zip-file!
    I'm using the "tight center" LUT. It vibrates a little even when standing still but that's the price for the smoothest and tightest feeling with the G27!

    Little Info for all: I created another LUT, that's works like the gamma setting, just better!
    BUT you will have to lower the "Gain" in the Advanced section of the wheel options to 50%!

    Thanks for the write up i think i will try this! have you tested with a g25?

      Thanks for the Stars :)
      I only have a G27 and a friend has a DFGT. The g25 and g29 are pretty similar to the G27. If you click on the full guide thread (linked above), you'll see many people using these LUTs for their g25 or g29! :)

    I just wanted to thank you for improving my Assetto Corsa experience immensely. FFB on my DFGT now feels much better.

    Good job. Gamma works well, I like it. Others are very good starting point. Might be differences of wheels or mine might be bit worn out but Tight Center is way too harsh for my wheel(I'm poor, don't wanna break it more that it is already), so I had to do minor adjustments. Normalcenter is ever so slightly numb, which might again be my wheel. Didn't test DFGT.

    You, my friend, is a miracle worker. I bet a whole lot, if not the majority of us, do not have time to explore those settings until satisfied. You've donated your time and expertise into amplifying other's experiences. I hope I can make a video about it for my small YouTube channel so others can enjoy such exponential improvement. Thank you very much, I do really appreciate your work.

      Thank you for that kind Feedback. One thing you got wrong though: I donated my time for MY experience :D (ok, the Guide etc. was for you <3 )
      Don't forget to post me the link if you do such video! :)
