Logitech G29/G920/G27/G25 FFB Thread?

Hi all.
I hope you can help me for a little.
I have experiencing weird ffb behaviour on my g29 sometimes. Sometimes it happens in middle of circuit, sometimes right after starting a engine when I want to exit pits in quali... Ffb goes to full force to right steer with no reason and holds it until I unplug USB. After usb reconnection wheel perform standard calibration and full steer is no more. After that are ffb working too, but in some weaker way... Ffb isn't such detailed, like before and only game restart helps to run ffb correctly again. Any advices, pls?

 

No solution, but it is happening quite a lot to lots of different wheel users around the forum, so well reported and they will most likely get to the bottom of it.

 

Is possible that is madness engine related issue?
Because when I buy my g29 from a friend, I've been played Project cars 2 for few hours and exactly same thing happened. But at first time I was surprised and don't realised that I have to disconnect it and wheel motor gets overheated and gone away in cloud of smoke :-/ I was lucky to get new wheel in last month of its warranty It happened again here in ams 2 with new wheel, so I was confused where is problem...
Thx for your info.

 

Do you have tried the wheel with any other sim?
Same behaviour?

 

Sadly I don't.. I've played Asseto Corsa for abou one hour only. don't like it, so leave it... But I'll try it tomorrow.

 

I had same trouble in PC2, absolutely randomly, and had to disconnect wheel, exit pcars2 and restart cause wheel keep forcing to right. In ams2 it turns to right but after 2 seconds it returns to center and it"s only annoying....
Never happened with rr3 rf2 ac acc lfs netkar ..
G29 here.

 

Just so you know, this is a quote from Renato on the RD forums:
"Just as a clarification, we wrapped development of the FFB code for v1.0 @ v0.9.3 - the fact the mechanics of the system were set then however doesn’t mean we were not still fine tuning the parameters in the default script and within each car. The differences in v0.9.5 are limited to this fine tuning process, which is not to say they are small. We‘ll still be going through that process in the coming weeks until v1 release. We will also review the code for bugs when needed, one of them being the initialization issue causing the wheel to pull right in some circunstances."

I'm on the G29 - This is the best custom file I've found so far. In game settings are 85/75/70.

 

G27 and default for me. Feels pretty excellent. Tried couple of custom files, had little bit better feel of weight transfer/rear end but i like more of the smooth feeling of default ffb. It's anyway one of the best default ffb's of any sims currently in my opinion.

 

Hi, G29 user here.

I'm using custom profile, my current file:
- modified scrub,
- scrub/rack force smoothing at very low speed/standstill,
- engine vibe off,
- deadzone removal (tighten),
- more linear output (scoop knee/reduction),

and settings:
- GAIN between 70-100 (depends on car),
- LFB mostly 0, 5-10 when lower gain,
- FX 80.

THE best FFB I have ever experienced in any racing game so far. I can feel everything (kerbs, bumps, road surface changes) even on straights.

If you want to find your values for the 'tighten' and 'scoop' functions use the FCM 1.20 tool (google > Force Curve Modifier pcars).

Hi Tom,
This completely changed the game for me. I am new to sim racing and didn't know what FFB should feel like, but this is definitely it. Now I need to replicate this in ACC and PC2 . Quick question on the 'tighten' and 'scoop' functions. I ran the tool but where can I find these values?
Thanks!

 

1. First you need to start > Wheel > Force Test > Start Test
2. When the test is over you should get something like this
3. Click on "Calculate best R, value" and adjust values in the red box

 

A quick experiment with "Kerb enhancement" from @NuScorpii Heavy Messing V2.5
The "kerb_scale" variable controls the strength of the effect. I tested the file on P1 and kerbs are definitely more pronounced

Tom do you still use this custom file and settings or have you changed anything in the meantime? Thank you!

 

GJDriessen, currently I'm using a different file and settings (woks even better). I will post it later.

I'm uploading my current file as promised. Settings for all cars: 100/20/85/0 (gain/lfb/fx/damping).

Updated file,
i removed rattling by replacing scrub ratio with built-in variables (FL/FR_slide).
File is now basically Reiza default with 3 additions:
- rack force compression for high down force cars,
- dead-zone removal,
- corrected wheel force output

Update (24.10.20)
- added subtle engine vibrations when revving (car parked),
- added gearbox fx,
- adjustments to rack force compression (threshold, ratio)

Update (12.01.21)
- updated version number to 1.1.0.1
- added Reiza's doom_check

Update (22.03.21)
- version 1.1.2.5,
- adjustments to tyre scrub effect,
- better balance of high forces

Update (04.04.21)
- version 1.1.3.5,
- minor adjustments in parameters (scrub, relative function) for better balance of forces

Update (26.04.21)
- version 1.1.4.0,
- code cleanup

Update (03.05.21)
- version 1.1.4.5,
- adjustments for karts (less harsh feel)

Update 04.07.21
- version 1.2.x.x

Update 20.04.22
- version 1.3.x.x
- more info here (RD)

Update 22.06.22
New alternative file with no additional effects. Remember to remove _ALTERNATIVE_NO_FX_PURE_RACK from file name before use. file removed

Update 15.06.23
- version 1.4.8.1,
- revised file to utilise new V1.5 PHYSICS
- removed all additional canned effects,
- in-game settings 100/15/85/0 (GAIN / LFB / FX / DAMPING),
- wheel software settings (LGS, G hub) > centering spring strength: 1 %

Set master FFB gain to 100 and use per car FFB gain to tweak center feel and strength of the wheel in corners.

Some suggested per car FFB gain for cars with new physics:

• Formula Junior: 106
• Formula Inter: 106
• Formula USA 2023: 106
• Formula Retro Gen3 > McLaren MP4/1C: 110
• P1 Chevrolet: 105
• P1 Honda: 105
• P1 Judd: 106
• P1 Nissan: 105
• P1 Ginetta: 110

 

It's subjective of course, but for me TomP's settings with the suggested values give me a lot of wheel rattling when the rear tyres loose traction (slip effect?), which makes it impossible to save slides. Reducing FX to 10 removes that, but then you lose a lot of the feel and confidence entering corners. This was tested with the Super V8 at Curitiba, which is the car I think struggles the most from bad FFB because going over the limit punishes you immediately.

On the other hand, the settings Pete Baldwin posted (Silver Santos v1.0) feel very good to me, although I went to GAIN 90 LOW 0 FX 30 to remove the excessive rattling that is present in many of these files. Now I can feel when the tyres are locking up under braking as well as lateral grip at the limit in the fast corners. The Super V8 is still pretty finicky to drive, but the Opalas for example feel superb.

I like that both these settings allow reducing LOW to 0, which I think helps bring out a lot of the details that are often missing on the G29.

I retried TomP's settings. They're not bad, but I still prefer Silver Santos v1.0. I also reduced GAIN to 65 to make it easy to control the car with one hand, but upped the LFB to 35 to get more natural centering force from the front tyres when the rear comes out. FX was lowered to 20 since that's the most I can run without rattling when the brakes lock up in cars like the Ginetta GT4. Now the Super V8 and the FWD cars really came alive. I would still like to get more information about weight transfer, like it was possible in AMS1, but it's pretty nice now.

 

I have updated my file

Hi,
I'm driving with a G923 (PS4)PC wheel since yesterday, coming from a 920.

I'm happy about the way it feels/FFB in AC/ACC/RF2 and also in AMS2.
I love the dampening feature, a very very silent non nervous wheel in AMS 2.

But ingame there are no(not yet) 'G923' settings I see?

In G Hub I calibrated my G923 and in AMS 2 I see the Caterham 620 Streetcar and its virtual steering wheel is not exactly syncing with my G923 rotating it to almost the max you see the virtual wheel staying behind the G923 in degrees/visually.
Same goes for M1 Procar, but Ultima 720 Streetcar is perfectly sync-ed just like in AC/ACC/RF2

Anybody info/tips?

Obrigado

Cheers
Robin

 

In Game and in LogHub you setting 900* and wheel sensitive to default 50?
