This was a game changer for me.
From AC Logitech wheel thread:
"For Logitech Profiler:
100% overall and use AC's minimum force for your wheel's particular deadzone, or use this overall setting for your deadzone and not AC's min. force setting. For example - I use 100% overall force in profiler and 16% minimum force in Assetto Corsa because my particular G27 requires at least 16% force to respond *(determined using wheelcheck.exe iRacing tool) But if I didn't want Assetto Corsa to handle this task, and I wanted the profiler to manage this - I'd set 116% overall force in profiler and 0% minimum force in AC main menu advanced controls. AC handles this better than Logitech Profiler though in my opinion.
100% spring in profiler, though 99% of people use 0% spring, and I did too for years and still do in other games - but somebody who sounded really smart said it's good in AC and I tried it and it made such a small difference that I can't really tell between 0% and 100% spring, so either way it doesn't matter to me. 0% spring in profiler is fine, 100% spring is fine - try them both for yourself.
100% damper in profiler because that way if you want to use any damping in Assetto Corsa, you will be allowed to. However if you don't want any damping, you can still have no damping even with profiler's damping set to 100% Damping is setup in the game, the profiler just determines if it's allowed or not and 100% in profiler = up to 100% is allowed if you want.
0% center spring as this is just a gross feature for non ffb games, checked the box though because for some reason people say to do that - can't tell a difference with it checked or unchecked personally.
Check the box for allow game to adjust obviously and 900 rotation obviously. Also, it's important if you're not doing this in the global settings but rather if you have a specific profile for AC to make sure the path points to: x:\Steam\SteamApps\common\assettocorsa\acs.exe (x being whatever Drive letter your's is of course)
In game I use 100% gain (I set my gain for each car individually in the General Tab in the pits using FFB anticlipping tool to determine perfect FFB for each car, then save the setup and it will always load up w the perfect FFB)
In game: 0% filter because the raw forces are better
In game: 10% damper (0% is good, but I use 10% to add a bit of 'weight' to the wheel)
In game: 16% minimum force (used a program called wheelcheck.exe to determine that value - reduces deadzone)
In game: 2% Kerb (G27 rattles when this is too high, 2% is enough to feel it without the rattle)
In game: 0% Road (canned/fake effect? Didn't like it - it's sorta like Rumble on a controller for bumps in the road, if using it - use very low amount)
In game: 0% Slip (same as above, canned effect - using this makes good drifting more difficult)
In game: Gamma, Filter, Speed Sensitivity, Brake Gamma = ALL default, don't wanna mess with these - leave them default.
In pits: General Tab can set the FFB gain to whatever that particular car needs since gain is 100% in both profiler and main options = linear setting with full range available here.
I tend to leave Damper on 100% in this General tab (so it allows 100% of my 10% damper choice from the main menu to add in the 'weight' to the wheel so it feels better around the center)
To determine what Gain to set in the General Tab, I use an Assetto Corsa app I downloaded here (check forums for FFB anti-clipping tool 2.3)
For Logitech, having the correct gain rather than guessing is important because these wheels need a lot of force to feel something, but then easily get overworked by too much as well, so dialing in the min. force as well as the gain is important.

@R1600Turbo @Johnnypenso 116% strength on profiler and 100 gain doesn't even clip, it's awesome.
