Logitech G27 Force Feedback FFB Assetto Corsa - A.S way

WheelCheck.. FCM tool Lut Converter.. FFBClip App .. tried them all . . and wasted alot of time testing pretty much every guide out there.. till i was like.. ok . time to think.. and not replicate things like a parot.. and VIO LA.. never been so good before. Let me know how it works out for ya. Enjoy !

G27 Owners .. simplicity is DEVINE!

The confusion and frustration of the G27 not being a good wheel and the pain to set it up correctly.. its your christmas today.. try.. and thank me later.
Without going into once again confusing technical details.. straight forward.

1)
120% in oder to eliminated the "deadzone behaviour" or interfacing bug of the G27 completly - just by doing that

40% - 55% dampening, because otherwise your wheel will turn loose if car isn´t rolling. Standing rubbers still provide resistance on the steering wheel. ( i have to in 70% as the not roll resistance should be higher than the slow roll one)

Under C:\Users\UserName\Documents\Assetto Corsa\cfg in the controls.ini file edit like this:

[STEER]

[FF_ENHANCEMENT_2]
UNDERSTEER=1

Create a file Linear.txt file in the C:\Users\UserName\Documents\Assetto Corsa\cfg folder, open it with notepad or editor and add:

0.00|0.00

There you go, you wanted a linear G27.. there you have it now.

After that, rename the Linear.txt file to " Linear.lut" (lima, utha, tango) and save it.

4)

Open the ff_post_process.ini file and change it to:

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

[GAMMA]
VALUE=1

[LUT]
CURVE=Linear.lut

5)


Open the assetto_corsa.ini file under :\Steam\steamapps\common\assettocorsa\system\cfg and make sure the following part look like this

[FORCE_FEEDBACK]
FF_SKIP_STEPS=1

[FF_EXPERIMENTAL]
ENABLE_GYRO=0
DAMPER_MIN_LEVEL=0.0
DAMPER_GAIN=1.0

6)


ingame should now look like this:

Here you can also use 60-70% as GAIN Main and Filter ZERO !!

Your wheel with 120 gain is like this (blue line):

Yes you have zero dead zone, but huge non linear behavior.
Hey folks... Coming to the party a bit late (and OMG that is a LOT of pages of thread in such a short time :-P) but am wondering how this force data was generated? Would be curious to repeat the test on my own wheel (also a G27!).

I have been genuinely meaning to try Rasmus' settings for months now, because I've not been entirely happy with the AC FFB (tho it still kicks the truly awful PCars FFB into the next galaxy). However, I've never quite found the energy to start the process because it's such a pain to have to restart acs.exe after each tweak. That, combined of course with the lack of clear documentation about what each setting does, which is exactly what leads to the spread of what Stefano called snake oil... There will always be some subjectivity in it all too. So far though, I've been using my time behind the wheel to just drive ;)
 
very simple for me

In wingman profiler all 100%

In game...
GAIN 100%
ABS 20%

everything else 0% / off

No LUT

Hi Stefano,

Thank you very much for sharing :thumbsup:
My wish is, would you update the first post of the official Assetto Corsa forum Logitech G27 thread with your settings advices.

http://www.assettocorsa.net/forum/index.php?threads/logitech-wheels-official-thread.3295/

I think it could really help lot of guys a little bit lost in this.

The must could be with that, few words about additional options available (gyro, Lut etc .....) but in a so simple way as your post settings ;)
