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.

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

How to use:
  1. Run WheelCheck
  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:

What an improvement. I was struggling to keep the Nissan Skyline, and similar cars from under steering. I also couldn't feel when the car was loose, or other subtle things. Great smooth control now. Thanks
Must have!
Brilliant tool. Saved ACC for me. Many thanks.
My G27 fells soooo much better. And this took all of 2 minutes
Feels amazing
I have no idea how this program works and what exactly it does, but my handling (T150) feels way more realistic now. In case anyone could explain it for 5-year-olds, I'd be thankful.
Am I missing something? II download and open the app. It asks me to locate my csv file. I go into dockuments/Assetto Corsa/cfg but nothing is there.

My ff_post_process.ini is the but no csv.

What am I doing wrong? Im ripping my hair out
it seems that all of our wheels need a good calibariton; this tool does that; incredible!
Great app but how can i increase the strenght without messing with the overall settings?
cant get it to work anyone know y?
Perfection!! Wheel feels incredibly natural now on all fronts...general tension, feedback to the road, bumps, etc. Thank you so very much! I came across this mod by accident. It should be listed by every youtuber as a must have.
Anybody else having the problem where i the link to wheel checker isn't loading so i cant download it :(
An absolute must have for G29 owners. Complete game changer.
I don't know what the hell happened, but I'm faster now. The central feel of the steering when transitioning from left to right no longer has that unnatural heavy zone at dead center steering with my clubsport v2.5 and formula v2 rim.

Bro, thank you. This should be applicable to all sims. Work harder, get this out on EVERYTHING!!!!!!
Content Manager+LUT Generator: race canceled. There is a solution?.....problem resolved, error associated with lut file name
very useful and effective
I can't stress how excellent this is. This, together with WheelCheck completely fixed my wheel's weird behavior. Thank you so much!
Thank you !
TX user here, feels much better :)
I just got back into racing sims using my ancient WingMan FFB wheel. Wheelcheck and the LUT generator have made a huge difference - no more clattering and shaking on the straights in AC. Thanks!
I love it but one thing the review doesn't state is where to find the CSV files. If you are wondering they are in your Documents Folder.
This greatly improved the feeling of my Thrustmaster TMX Pro, thank you!
Brilliant, worked exactly as expected on my G920. Nice, detailed and heavy force feedback.
For everyone wondering how to download the lut generator. You have to make an account and then there will be a red icon that says download to the right of the title.
Works great with my Fanatec Forza Motorsport CSR Wheel
