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

    Great instructions. works great. If you use damping: make sure to enable damping on the drop down!

    I own an old Driving Force GT and have spent a lot of time tweaking it and Assetto Corsa's settings to try and improve the sim's (to me) lacklustre force feedback. No joy - AC looked lovely but was very disappointing to drive.

    Your LUT Generator, the Wheelcheck program and your clear explanation of how to use them have transformed AC for me. My wheel feels terrific now that the deadzone has gone, and I am picking up lots of subtle information that was missing previously. Driving is now intuitive. Not only have my laptimes improved but now I can sense the different behaviour of each car. AC has gone way up in my estimation and so has my enjoyment.

    Thank you very much. :-)

    Works as advertised. thanks so much for putting this together! I did however feel like the effect was a bit too much. it felt like the ffb would ramp up way to fast, then it would feel like clipping. so i went to the generated LUT and halved the difference between the numbers on the left and the numbers on the right, effectively halving the effect. so if you feel the change is too much, then do that. yes, i had to do the math for every line, it wasnt fun lol but the result is NICE. miles ahead of the straight 1:1 that the game was using before.

    LUT Generator & DFGT - makes a difference. With a FFB Clip app its a must have for enjoyable FFB. Thanks!

    is there something i miss? my wheel seems so light..
    i already put the minimum force to 0 inside AC game on option..
    im using g25..is this also works on dfgt?

    Suddenly my Fanatec CSW V2 doesn't feel empty anymore. It felt like it has a life now and is responding to the tracks. I could feel so much more details after applying the LUT file.

    Previously, my wheel would just feel heavy and no details at all. After using this and following the instructions, I finally had no more remorse of owning this wheel.

    G27 user - Why I didnt know about this earlier ..... .... .. Unbelievable , Precision /Transition Hundreds times enhanced and smooth, more 'Natural feel'

    First try I was , Seconds..faster.
    Get it .. ^^

    I loved this. Made my FFB much more precise.. Only downside is that my wheel clips a lot easier than before.. When it's not clipping, it's presenting itself as very weak.

    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??
