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
  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

GUYS! I found the fix! So if your LUT file isn't there and it says 'open' in file manager instead of 'save,' it is probably already saved. Just look at your Documents! The Documents should have it. From there, you can drag the Excel file into Content Manager as a new LUT file and then save it there! YESSS! (Also, 3 stars since it was SUPER hard to figure out and there should be better guides on this or something.)
Used this and my wheel (TMX) responds better now.
my g27 wasn't responding :)
my solution - reinstall Logitech drivers for your wheel
Downloaded Wheel check & LUT Generator, Started wheel check then plug steering wheel in, followed WC instructions.
Ran LUT Generator, install CSV file from WC to create new LUT file.
Ran Content Manager to import LUT file and Boomschuckaluka sorted!
i've figured it out boyzzzz, i had the problem of wheelcheck not responding or actually making my wheel calibrate, i tried restarting, reinstalling GHUB , turning off my antivarius etc and still nothing worked, i have the g20 and what worked for me was installing the older version of ghub - Logitech gamming software 9.04 and uninstalling the current GHUB and when i loaded up wheel check and tried it , that worked for me, i hope this helps you out(:
hkf
you have to click the top right download button for the actual lut generator, otherwise very helpful
LMAO guys wheel check is separate from LUT generator. The download link is only for the wheel check. you have to make a race department account then download it. Thank me later.......
My Wheel wasn't connecting to Wheel Check but I finally fixed it with a single action. If the wheel is not connecting to Wheel Check try moving the USB plug into the top one on your PC this worked for me and my G29 spun and when I opened wheel check and selected a test it immediately worked.

other information the File Wheal Check makes is in documents and make sure your virus blocker is turned off.
Wheel check will show the position of your wheel at the top if you are connected. If you are not, it just says (x)(y) and no numbers.
Overall it's really confusing and outdated I'm giving it 3 stars
!! see TAW_StarDog review for more info about Content Manager.
i need help with the wheel check when i open it and put the value to 50 and the spring force to log 2 my wheel keeps spazzing left and right for mintues is this the check ?
For those that don't already know. CM now has an inbuilt Lut generator. We only need to creat the 'WheelCheck' file. Then use option in CM to import & convert the file to .lut. It also creates the correct 'Header' file & entries at the same time.

Enable 'Post FFB effects' in FFB controls tab, make your selection from the import window & your good to go...
fixed wheel checker not working by uninstalling all logitech software and following this video. so install the old l ghub in the vid and it should work.

tried all the methods u can imagine, i extracted it in 7zip , runned it in 7zip, restarted my pc like 10 times, downloaded older versions of logitech, deactivating my antivirus, done like 15 or more of those calibrating tests and never got the "mylut" file , this thing just wasted my time
I have followed your instructions step by step and then all of a sudden, my humble Logitech g920 became really amazing. Thank you!
So guys...I've been struggling getting this WheelCheck to work. Tried everything recommended below. Nothing worked until I read about someone reinstalling their software for the wheel. In my case it was Logitech G Hub for my G29 wheel. After reinstalling it, I opened Wheel Check and selected Log 2 and the wheel check started automatically.
So guys, try reinstalling your software, it might work for you as well.
GUYS LISTEN HERE, FOR WHOEVER IS TRYING TO DO ALL OF THIS NOW.
I read many reviews in which all says that u ran in various problems.. Ex WheelCheck doesnt do the test, or the file is not generated. I HAD THE SAME ISSUES.
i've solved apparently every one of them, so...
The first thing, THAT WORKED FOR ME ATLEAST. Was opening the RAR file with 7ZIP, and then i opened wheelcheck.
And finally it was "responding", like it detected the values etc.
After i did the test, but i couldnt find the CSV file.
So after researching and not finding ****. I thought that maybe my antivirus was creating some interruption. AND THIS WAS THE CASE.

I HAVE AVAST ANTIVIRUS, i opened it and went to menu and then settings. And then i went to the "add exception".
IF U HAVE MY SAME ANTIVIRUS, OR ANOTHER ONE THAT HAS THIS KIND OF SETTING, TRY IT. So i added the "WheelCheck.exe" as an exception. And shortly after i did the test again, and it finally created the file.

the file was in "DOCUMENTS".

i give 3 stars bc this is rly confusing. And the author or whoever runs this, should put some fix guide for these new problems.
WheelCheck runs perfectly fine and generates the csv file. When I press open on LUT nothing happens, it does not take me to my files, it simply just does nothing. I tried disabling my antivirus, restarting and yet no luck.
Issues solved
Restart pc after installed
make sure antivirus is off
make sure content manager is closed and then it just worked for me
For anyone having issues running the test. Try extracting the Wheel Check files through 7zip as opposed to WinRAR if you haven't paid for a WinRAR subscription. Then procede as usual. Thats what solved my issues.
The Test in WheelCheck is not working i tried restarting my pc but its still not working pls HELP
