Apps LUT Generator for AC 0.15

[ALB123]

There is no point of having linear ffb with weaker wheels, because it means that only the highest forces give any feedback then.

You'd think there would be a disclaimer or something so we don't waste our time... Oh well.

Is a CSW V2 considered weak?

Is a CSW V2 considered weak?

As I recall its ffb is very linear by default, so no need for a lut there.

Thank you for your reply!

Is it possible to increase the center deadzone manualy? I have a g27 and when the wheel is centered the two motors are interfering with eachother.

I using lut generator gives me this error when I go to save the file :
ERROR INDEX out of range. requested non-negative value and less of the size of your collection

HELP

I also tried this with a CSW v2 and all my FFB is gone...

Hello, first of all thanks for the app. I like to have everything set the best it could be. I messured my wheel (T300 Ferrari 599XX EVO) with wheelchecker and set gain in CP to 80% (best linearity vs ffb strength) then I set AC gain to 100% and minimal force to 10. The ffb in game was very good. Then I found your app and tried to set AC ffb from LUT. But the ffb feels completly messed up. The wheel gives me all around minimal force and sometimes it grows very quick but unreal. Example: I am enetring turn in GT car (low/no force), in turn (low/no force), going out the turn (low/no force), on straight I am making minimal correction (suddenly high force). Can you please help me find the problem? Here is my FFB graph and LUT, and graph from LUT geneerator.

I have the same problem. Same wheel (t300 alcantara).

FFB is very muted (low) all around and In high downforce corners the forcefeedback is way way too strong, almost like trying to turn a brick wall. It happens when the FFB is clipping "red" in the FFBclip app. If you turn the FFB down to not clip, it becomes almost non-existent. Curiously enough, even though you barely feel the FFB in the corners, you still feel it very well when passing the kerbs.

On the T300 I'd recommend not to use the LUT. I tried it extensively and it really does not improve the FFB. Something is broken in this app, but I can't quite put my finger on it.

I run this with excellent results:

In the ff_post_process file
[HEADER]
VERSION=1
TYPE=GAMMA
ENABLED=1

[GAMMA]
VALUE=0.85

I recommend you guys try it out.

 

[Dan Costa]

its a shame then, because LUT made a very big difference on G25.

I'll try it thanks

G25 owner here but isn't consent on best linearity for T300 66% FFB in the Thrustmaster driver? Read that somewhere regarding BeamNG.Drive, where you can also import a wheelcheck file

Thanks Sakl, I will try it.

Yes the linearity is beter in lower FFB value. You can see it in my own measurement, but you lost the max FFB force. When you set 60% ffb gain in CP you have better linearity but when the game is sending 100% ffb to the wheel you get only 90% of max force of your wheel motor. It is always compromise between linearity and max force. In second PDF is measurement of my old Fanatec GT2. You can see same lost of max force with lowering the FFB in wheel / in controll panel but superb linearity.

does this work on OSw wheels?

 

[Enrico Fulgenzi]

Hi, i do everything as you describe but when i open the FF POST PROCESS, values are not correct and are as usual. how can i do?

 

[tlsmikey]

does this work on OSw wheels?

Not sure why you would want to do this on an OSW. You should have linear response due to the nature of the motor.

 

[Keanu Buschmann]

I don't really understand this mod. When the FFB clipps I got a pretty nice feeling. When there is no clipping I feel nothing. What I'm doing wrong there?

 

[kondor999]

Followed the steps for my TX wheel... Now it feels a little light around the center. Any one else with a TX/T300 have the same feeling?

Yes, I've got a TX and the FFB this produced was really bad IMHO.

Zero force in the middle and then rapidly too much as you turn the wheel. It's almost like it exacerbated the low initial force levels rather than boosting them like I expected.

Tried it twice, followed the directions exactly...and it made my TX wheel much worse. Went back to the normal FFB and it felt fine again (regained linear forces that were about as strong in the middle as anywhere else).

Not sure where to go from here, since people seem to love this.

 

[kondor999]

For me it actually broke the FFB feeling completely (T300). Forces around center got so tight that it was on-off, but out of that feedback became numb and flat. I tried with three different WheelCheck runs with counts 100, 200 and even 1000. Wouldn't really suggest it for such a sophisticated wheel, but I can see how it can be really useful for Logitechs with all that mechanical resistance and non-linearity as a base.

Agreed on that. It felt horrible on my closely-related TX wheel. But I had the opposite issue: Very numb/no force in the middle and then far too much once I moved the wheel beyond about 45 degrees rotation. And yes, I set min force to 0 and edited the ini file properly:

Weird - I've been using it for 6 months on my T300. Maybe run wheelcheck after you've warmed it up with a driving session? Try 100 step setting?
