LUT Generator for AC 0.15

ffb lut generator for enjoying linear forces on all wheels!!

  1. Akis
    What is this?
    This is a tool that produces an FFB lookup table for AC. It is used to (hopefully) correct the non-linear behavior of the motors located on our steering wheels.

    Prerequisites:
    This automated FFB LUT Generator for AC uses as input the csv file produced by WheelCheck.

    How to use:
    1. Run WheelCheck [​IMG]
    2. "Max Count" should be at least 50 in box. Lower values work, but 50 or even 100 give better results.
    3. Select "Step Log 2 (linear force test)" and wait until the test stops.
    4. Extract LUTGenerator.zip you've just downloaded wherever you want and run LUTGenerator.exe
    5. Open the csv that was just generated by WheelCheck.
    6. Save the generated LUT in My Documents\Assetto Corsa\cfg\ folder, eg myLUT.lut
    7. Open ff_post_process.ini located in My Documents\Assetto Corsa\cfg\ and make sure the TYPE=LUT, ENABLED=1 and CURVE = Generated LUT filename
    8. MIN FORCE should be set to 0 in Assetto Corsa!!

    After this, do not alter the FFB Strength in your wheel's profiler!! If you change the FFB Gain in your wheel's profiler, you should rerun wheelcheck+lutgenerator.


    Step 7 clarification:
    For example, if the file you produced with LUTGenerator is myLUT.lut, then this is how the ff_post_process.ini should look:

    [HEADER]
    VERSION=1
    TYPE=LUT
    ENABLED=1

    [GAMMA]
    VALUE=1

    [LUT]
    CURVE=myLUT.lut

    Gives my wheel a much nicer, 'tight' feel and seems to have made driving at the limit easier. Nice work!

    I found a simple fix for the G27 oscillation (should work with any wheel that has 2 motors):
    Go to C:\Users\[PC-username]\Documents\Assetto Corsa\cfg and open the xy.lut file with notepad.
    Now you want to edit the first one or two values (not including 0|0) depending on what you set the "Max Count" to. When you set it to lower than 200 just the first, when you set it to 400+ the first two.
    Now you just look what the second value is and halve it and replace the first value with it.
    Save file.

    Example:
    your lut looks like this:
    0|0
    0.02|0.205
    0.04|0.21
    0.06|0.215
    ...

    you replace anything that's on " " with "0.105" (cuz it's half of 0.21)

    0|0
    0.02|0.105
    0.04|0.21
    0.06|0.211
    ...

    When you still have problems on straight try to put "0" in the first few values.

    Still feels like I'm driving AC.....t300rs.....how the hell do I get the wheel to stop wanting to seesaw back and forth??

    I tried this app because the FFB on my CSW V2 felt sometimes to twitchy. But with the LUTGenerator, i have no feeling in really slow corners. The rear end comes around and you won't feel it. Maybe its me, but i stuck with the standart FFB.

    I can finally enjoy AC properly, this thing is a lifesaver. If I still could, I would have refunded AC because of the FFB, if I knew about LUT, I could have enjoyed it from the beginning. I knew the G29 is capable of much more if you tune the FFB to it properly, sadly Kunos can't seem to be able to do that. Thank you so much for this!

    Just don't know how I never knew about this. My old G25 just become a lot better in AC. Also it was so easy to make the LUT.

    Can FFB Clip still be used or will that cause problems ?

    My G27 feels like it got upgraded to a 500€ wheel :p
    Thank you so much for revamping my interest in AC!!

    Akis, You are the MVP.
    Man, you just transformed my experience. I feel like driving a real car while using my Fanatec CSW 1.
    I just need to dial in the right amount of force now.
    The self centering is amazing. Like I never thought it would be possible. Just like a real damn car. I can even teach people how to drive now.

    This is insane! AC turned very frustrating to me when I realised the transition from small to high forces was too quick on my wheel. I felt nothing in the straights/slow corners, yet the forces went so high in fast corners that I couldn't raise the gain without clipping. This was not something Min Force could change.

    And then I tried this. Game changer. I'm back to being friends with AC now. :D

    I gave it a try on my T500RS and I imminently started sucking once I set the generated LUT, it could be just me but I get much more FFB input with the default GAMMA.

    Makes what I already thought of as excellent FFB from AC even better, so much detail and nuance
