Hi folks,

I thought about buying a G27. If someone can help me out please give me a notfication or post on this thread.
Unfortunately, this wheel costs now 500 Euro on Amazon and I couldn't find it on any shops in my county.

Greetings

CEL

Not sure about the G29, but G25 and G27 detect the wheel rotation with a small optical encoder wheel. (sensor counts the slits to detect rotation) That part is bit fragile plastic and appearently tends to break.
Then the sensor gets confused by the cracks or the encoderwheel falls completly. (=random sensor signals)


There are some threads about in forum, here someone fixed it with glue:

or replacement part: http://www.cmlaserservice.com/page_g25_g27_optical_encoder_wheel.html

Driving Force Pro dont have this protecion so You always have full 900 degress i dont know how G25 works but i think is behave same as G27. Sorry about bad english

Just a quick note: G25 did not have this "soft hard lock", it was introduced with the G27, I guess too many wheels broke apart during the years, it sure sounded/felt bad during the calibration and extreme counter steers.

Quote from Flame CZE :

I have a similar issue with my G27.

It's quite weird, whatever I set in the driver software, the actual rotation is about 20° smaller. So what I usually did before test patch P2 was set it to about 20° more than what the actual lock should be in game to compensate for it. It must be a bug in the Logitech software/hardware or something.

So now in P2 I set it to around 880° in LFS so the rotations match.

This happend becouse logitech DFGT G27 have something like soft stop when wheel is going to full lock and when wheel is around 880 degress force fedback is trying to slow down wleel becouse limiter can break when wheel hit full lock to fast same thing happend when You set to 720 degress in profiler in game will be around 710 degres becouse off this. This is protection becouse wheel can be damaged without this. Driving Force Pro dont have this protecion so You always have full 900 degress i dont know how G25 works but i think is behave same as G27. Sorry about bad english

Quote from SimulatorRental.com :

I was curious, because setting it to about 850 on a Logitech G29 seems to match up really close to actual wheel position. Not sure if this is the case on all G29 (will check when I get more than 2 of them)

The "Wheel turn" setting in LFS must exactly match the actual amount your game controller wheel can turn. It's not really a user preference, it's either right or wrong. So for a G27 that should be 900 degrees (if the wheel is set to allow 900 degrees in the driver software). Otherwise there is no hope of LFS matching up your wheel with the in game car wheels.

Today I did the auto-centering function.

If a force feedback wheel is in use, LFS tries to move it to the centre during the two seconds after the car is reset (including race start or leaving the pits).

I think this will be helpful as it does often happen that the wheel is rotated 360 degrees. I've tested on the G27. It will be interesting to know how it works with a variety of wheels.

Hi,

Can any one tell me, where i can find car setups?
Hopefully a full list of setups (S2 cars) and im driving G27.
I want to try fast setups

Thank you

I recommend using 'remove deadzones' with the g25. I used to not be able to use it because the wheel would be off centered, but now that we can manually adjust ranges, I can center the wheel while using 'remove deadzones'. My g27 feels much better with that feature.

Controllers may be plugged in and detected after LFS is started

I tried this with my G27. It detected it after I hit refresh but the wheel was near impossible to move.

One thing that would be nice would be the ability to calibrate a wheel, whilst on a server, without having to join first. Joining with an uncalibrated wheel has always caused it to go into a motorised spasm before shift + o is quickly entered. If you go to options when spectating, it is reading the input of the spectated car. Perhaps an option to calibrate the wheel from the pit screen/options button in the pit screen?

...I'm also interested to hear from anyone if the automatic controller setup seems to work OK....

Works like a charm for me (G27)

Hey, tried out the new automatic config (by deleting my old con files) and the axes weren't correctly assigned.

• My throttle pedal (axis 2) was assigned to Brake function
  
• My brake pedal (axis 1) was assigned to Throttle function
  
• My clutch pedal (axis 3) wasn't assigned to any fucntion at all.
  

My wheel is a Thrustmaster RGT FFB with Clutch.

Quote from MadCatX :

Since you implemented some wheel-specific options in LFS, is there any chance you can look into supporting the LED lights on G27 & G29

Although I wouldn't make much use of it on my wheel, I think G27 and G29 are some very popular wheels and many players would appreciate this!

Have just spotted the calibration discussion.
I probably won't get a chance to test the patch today (though the text isn't clear about whether the manual calib stuff ended up in the patch anyway).

However, my thoughts FWIW: I do use the calibration system. It's a little flakey, yes, and it's a real ARGH moment every time you fire up LFS with the wheel unplugged, but it can be useful. The reason I really use it at present is because my G27 pedals are misbehaving quite often, and now and then I need to move a pedal min/max point to reduce the impact.
I guess there are probably other ways to achieve this though?

(Btw, I have looked a few times and can't seem to find replacement pots. Contact cleaner helped for a while...)

@Scawen:

Since you implemented some wheel-specific options in LFS, is there any chance you can look into supporting the LED lights on G27 & G29 so I can stop maintaining my horrible hack that makes them work with LFS? There is no need to use the Logitech SDK and it all should be a matter of a simple


where "packet" is a pointer to a DIEFFESCAPE set to this

"wheelData" is a structure looking like this:


"size" in WheelData is to be set to "sizeof(WheelData)" and "versionNbr = 0x00000001". Contents of the LedsRpmData are hopefully self-explanatory...

Seems all too work correct on g27 np here

0.6N4 is now available with more controller support!

Please read the list of changes.

Please could some of you test the automatic wheel / game controller setup?
To do that, rename or move the relevant .con file in LFS\data\misc before starting LFS.

https://www.lfs.net/forum/thread/89352

Changes from 0.6N3 to 0.6N4 :

Controllers :

Controllers with 5 axes now default to combined brake / throttle
Combined brake / throttle axis now defaults to correct direction
Automatically set Clutch setting to axis if wheel has clutch pedal
Automatic preset is now attempted on first of multiple controllers
Controller screen in game now shows correct pedals and steer gauge
New joystick look mode using two axes to control look direction
Arrow keys can now be assigned to wheel buttons (default D-pad)
Default 900 degrees turn for Logitech G25 / G27 / Driving Force
Attempted reasonable presets for Thrustmaster and DFGT wheels
A scroll bar appears if there are more than 16 available axes
Removed axis calibration system that had various problems
You can now type in the active range of an axis function
Typed range can exceed input range to reduce axis effect
Look Roll axis function now has a full 360 degree range

I plan going buy new Wheel and pedals. No need Gearbox Shifter. (Don't care expensive price because Pro quality)
I need work for PS3/PS4 and PC
PlayStation compatibility: https://www.fanatec.com/forum/discussion/187/playstation-compatibility?a_aid=gtplanet

I played:
-Gran Turismo 6 - PS3
-Gran Turismo: Sport - PS4 in 2017
-Live For Speed - PC
-ETS2 - PC

Example price:
Option ABC

A) Logitech G29 - 300€ (Sell G29 pedals 60€) + Fanatec ClubSport V3 Pedals - 360€ = 660€ - 60€= Total: 600€.

B) Thrustmaster T300RS/T300 Ferrari GTE - 300€ (Sell two foot pedals 25€) + Fanatec ClubSport V3 Pedals - 360€ = 660€ - 25€ = Total: 635€.

C) Thrustmaster T300RS/T300 Ferrari GTE - 300€ (Sell two foot pedals 25€) + Fanatec CSR Pedals EU - 100€ = 400€ - 25€ = Total: 375€.
I don't know, Fanatec CSR Pedals EU it work for T300RS or T300 Ferrari?

Wheel both are great quality?
G29 has 900 Degree
Tech Spec: [Dual-Motor Force Feedback high-quality, Helical Gearing with Anti-Backlash, Overheat safeguard, Hall-effect steering sensor]

T300RS/T300 Ferrari GTE has 1080 Degree -
TechSpec: [New dual-belt, friction-free optimized mechanism, Brushless Motor Technology Next-Gen Force Feedback, 16-bit resolution, i.e. 65,536 values on the steering]

What you think option?

C option is great enough but it will work CSR Pedals EU For T300? also PS3/PS4 with CSR Pedals work too?

*Fanatec CSR Pedals EU For T300 will work? and work with PS3/PS4?

-Fanatec CSR Pedals EU: http://www.fanatec.com/eu-en/pedals/csr-pedals-eu.html?a_aid=gtplanet
-ClubSport Pedals V3 EU: http://www.fanatec.com/eu-en/pedals/clubsport-pedals-v3-eu.html?a_aid=gtplanet
both pedals are work:
Platform compatibility (PC, Playstation 3/4, Xbox One / 360 etc.)

I can budget only 450 Euro. (I have only G27 wheel, can buy just Fanatec V3 pedals, Later get new Wheel save money)

Quote from Scawen :

Is everyone OK about losing the calibration thing?

Back on topic (sorry for the feature request ):-

I have a G27 with a load cell brake mod - I have previously used the calibration in LFS to limit the axis to a realistic pressure range. I am currently using a tweaker in Windows to achieve the same effect so is no longer an issue for me.

I would avoid removing options as "configurabilty" is one of the great things about LFS.

I never used calibrating in lfs But now I have a feeling things get changed that i don't want do I need too test?

btw G27 here

Quote from Scawen :

And do G27 owners get this bug too? The BUG: unplug the wheel's USB before you start LFS. Start LFS, plug in the USB. The wheel does its centering thing and when it is done, I can click "refresh" in LFS to get access to the wheel. All is good but one thing. The wheel only turns 90 degrees each way. The only way to get the full range is by clicking on another window. Suddenly the wheel can turn 900 degrees again and I can click back to LFS and all is OK.

I do not remember having had such "90 degrees each way" bug.

I tested to unplug wheel and start LFS and then plug in. On Win 7 64bit, G27, LFS 0.6N
Result was that the wheel was "fixed" to center position - basically 0° rotation. Going to desktop and back did not change it.
After pressing shift+C the rotation was working again with 720° (as I had currently set in logitech profiler)
However all buttons were set to "none" in options.
Restarted LFS and everything was okay again. (all buttons worked, rotation okay)

Bit related, after years I am still not sure I understand how to setup wheel rotation degrees.
There is three places to set it:
1) In logitech software
2) In LFS, options menu
3) In LFS, setup screen "controller wheel turn"
When I adjust rotation (going from roadcar to formular etc) I always set it in all places 'just to be sure.'

I've been on the case, making various improvements.

One thing: As I knew the axis calibration system was a bit annoying and usually forgets calibrations (e.g. if you ever started without your wheel connected) I started to try and code it so it saved a separate calibration setup per controller file. I ran into a little difficulty because of the way it was coded. Then I thought, why not just delete the calibration system? I am thinking that the wheel / gamepad / joystick / pedal manufacturers probably do calibration, so there is no need for the extra annoying calibration code in LFS.

So now I've commented it out of existence and it just assumes the full pedal range is available from the outset. So you don't have to move all axes to their full extent or click calibration lock.

Thought I'd better run this by you first, in case I'm missing something. In short, my general thought is that may be code that was needed in the past but is just a little annoying now.

Updates so far (in my version) :

Combined brake / throttle axis now defaults to correct direction
Controllers with 5 axes now default to combined brake / throttle
Automatically set Clutch setting to axis if wheel has clutch pedal
Automatic preset is now attempted on first of multiple controllers
Arrow keys can now be assigned to wheel buttons (default D-pad)
Default 900 degrees turn for Logitech G25 / G27 / Driving Force
Attempted sensible presets for Thrustmaster steering wheels
Removed axis calibration system that didn't work well

On the DFGT subject, I wonder if you see the same bug I see with the G27. And do G27 owners get this bug too? The BUG: unplug the wheel's USB before you start LFS. Start LFS, plug in the USB. The wheel does its centering thing and when it is done, I can click "refresh" in LFS to get access to the wheel. All is good but one thing. The wheel only turns 90 degrees each way. The only way to get the full range is by clicking on another window. Suddenly the wheel can turn 900 degrees again and I can click back to LFS and all is OK. This happens regardless of the "input when window is inactive" setting, so it doesn't seem like an LFS bug. I couldn't find any way round this other than doing the window clicking...

Quote from T3charmy :

Yep, only 5, Just bought the controller + wireless adapter for windows from the store about 3 weeks ago. LFS reports "Controller (Xbox One For Windows) Gamepad". Only have 5 axes. X axis, Y Axis, Z Axis, RX Axis, RY Axis. Also using the auto-installed driver. Running Windows 10 1511 at the moment. (Also see my previous post about an issue related to windows 10 tech preview).

Strange that mine has the RZ axis as well, separately. Maybe Windows 7 is better.

Anyway, now I'm setting it to dual axis if the controller has 6 axes, combined axis if it has 5 axes.

Quote from Flame CZE :

Could it be done so the Clutch setting is set to "axis" by default for steering wheels with a clutch pedal?

Good suggestion, thanks. I recently noticed the axes have a name when they are enumerated, and one of them is "Clutch" on the G27. So I've now used that and set Clutch to "axis" in this case.

Quote from cargame.nl :

Hhmm if we start to talk about DFGT then I cannot resist to stay silent ...

Thanks for the info and screenshot. In the multiple controller case, LFS isn't going to be very helpful at the moment.

Anyway, for single wheels, I've now set it to default to 900 degrees wheel turn if the wheel name contains "g25" or "g27" or "driving force". For other wheels the default is 270.

Quote from Eclipsed :

I also have DFGT,so I tried to connect after renaming old .con file. The name is shown as 'Logitech Driving Force GT USB' and most controls are like they should be - that is steering,pedals and shifter buttons behind wheel. Also look left/right buttons are assigned pretty logically and horn,handbrake,speed limiter and TC buttons are set to buttons,which have playstation cross,circle,square and triangle symbols. VR click is set to center button and virtual keyboard to small button below. For some weird reason gears 1 to 6 are assigned to few buttons and the shifter stick...
But for better overview I made a little grafical button chart,hope it will help.

Thanks for all the information and picture with numbers.

The gears are assigned because of the G27 shifter. I have now set it to only assign the shifter buttons if the name containts "g25" or "g27".

Quote from Ripley :

I have a Logitech DFGT wheel if that serves.
I can report back its buttons and such in 10 hours or so...

I was thinking about this. Sorry about my slow reply. Was a bit busy getting my head around the other things.

I could add an auto-setup for the DFGT. I wonder how similar it is to a G27. On finding an unknown wheel, LFS natively does G27 style button and axis assignments.

Please could you try renaming the .con file before you start LFS? Then start LFS and try the controls to see if anything's wrong with them. I guess there will be something!

Also, what is the name as displayed at the top right of the controller screen? So LFS can identify it and apply special setting.

If you want to report axes, please use 0.6N3 which displays the correct axis names.

Thanks!

That's a nice addition. When I bought my G27 I was unpleasantly surprised that I had to configure everything by myself in LFS - like it's some very rare imput device. It's good to have some default presets for - at least - the most popular controllers.
