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
    - damper: 0
    - 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% (unnecessary vibrations)
    - road: 5% (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.

    - 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 "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!

    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%!

    Awesome tutorial, many thanks! Drifting now is way more fun, gonna try this also in racing.

    I wonder if there is any difference on G29 - I think it has bigger deadzone than G27. I'm using your recommended LUT I am experiencing wheel wobble while driving straight when I give it a little touch. Any suggestion about it or it is intended to do so?

      Thanks for the review :)
      The wobble is a tradeoff for the tight feeling. Normally it should wobble but stabilize itself after a few shakes (if you just give it a slight notch and don't unsettle the car).
      If it's too much you can lower the car specific ffb with numpad minus until it suits you better :)

    I've followed the basic instructions and chosen the recommended lut (the one with 50% gain) and the wheel feels nice, def better than my last settings. Clipping it's totally gone while having everything firm and stronger, also I no longer notice the dead ffb center.

    I would recommend you to make a youtube video about this last lut that do wonders, it's the go-to place for a lot of people looking for assetto g25-27-29 optimal settings.

    Thanks a lot!

    I didn't know my G27 has that much force :D
    It is much stronger than my old settings, but still doesn't clip.
    When driving, the FFGClip app increases the gain to 180%, that seems a bit strange. Am I doing something wrong or is it supposed to be that way?
    1. RasmusP
      Author's Response
      Glad that you like it :)
      My ffb clip app goes above 100% too sometimes but after some heavy work on the wheel it goes down to about 90-135 depending on the car.
      The clue here is that ffbclip takes the output of AC before my lut amplifies it. I use the lowest profile in ffb clip without any clipping and the values are fitting :)
      I created the lut to take the ac game internal clipping out of the equation so you can just set whatever car specific gain you want and concentrate on the level that feels good and not bother with clipping!

    You goddamn LEGEND. I tried what seems like everything trying to get the FFB feeling right with the DFGT...then I came and plugged in your DFGT LUT file and bang....here's the game people were talking about.

    A thousand thank yous!!

    5stars+1 extra star for included LUT files lol. Love thiese settings!!! I like to drift for fun and these settings made it even more fun. In drifting the feel of the cars grip is essential and your settings (using your recommanded LUT) do excactly that it gives a really good feel of the car. Thnx for sharing :)

    I had a very loose deadzone at first, felt heavy vibrations when hitting the kerbs etc.
    I tried all 3 Luts and the difference is with my initial settings are enormous. Tightcenter you really have to work the wheel, it feels heavy. Normalcenter is what I used most. I'm gonna test the recommended lut more now.

    As a result of using these, when I turn there is no delay in turning (--> Deadzone) My G27 feels much better, a real pleasure. My lap times also become much better.
    Thanks for the work you put into this.

      If you ever have some questions just ask!
      Remember to put the ingame ffb slider to 50% when trying the "recommended" one!

    Takes AC to another level with my G29, simply astonishing!! Massive thanx for these LUTs. I've noticed with the 67 era F1 cars I get harsh vibrations while on the straight aways at Nords and other tracks. In the street cars and other non open wheel cars I don't have this problem. My gain is set at 50% via FFB clip and manual. Im using the "no clip but stronger" LUT

    Everyone with a Logitech wheel listed here... HAS to try this...
    It's made such a difference to Assetto...
    I can now plant the wheel exactly on the white lines of my tracks... Therefore... when I update their AI lines, I will have to give you a credit :)

    I'm currently using tight centre with 85% gain in game...

    I haven't really used my G29 much since I got it because it had a much too big deadzone... It was as vague as a chicken duck woman thing lol

    Superb! Thanks for taking AC to another level.
    I seriously think you need a donate button for this!!!

      I can only suggest to try the newest lut as it gives you more details AND a stronger feel.
      A donate button won't happen. Words like yours make me way more happy than a few $$ in my wallet! :)

      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! :)

    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.
