OMG, I finally fixed it - well, on my other PC anyway. It was these instructions that finally allowed me to do it.

---

Uninstall the software and make sure everything related to it is deleted then install this → http://support.logitech.com/en_us/product/g27-racing-wheel/downloads

The current Logitech drivers no longer support the G27 except as a Driving Force, which means all the buttons on the front will act as the same button in addition to other loss of features. As well as downloading no version of the gaming software newer than 5.10.127 as linked above, there are some hoops to jump through to keep the G27 working every time there's a Windows 10 update that loads new Logitech drivers.

After uninstalling all current drivers and software:

Open a Command Prompt, and type "cd %temp%". This will open your Windows temp folder. Note the prompt shows the folder location. Use File Explorer to go there and note what folders are present. Then run the installer for the 5.10.127 software and drivers, and watch for a new temporary folder to appear. Make a copy of that folder somewhere else for the future so you can skip this step next time.

(note by sfinktah: the directory name is random, there will be 3 directories made, just look for the one with the 2b-LGS folder in it).

Navigate to that temporary folder (or the copy you made) and then go further into 2b-LGS-x64/Common64/Logitech/WMDrivers. Right-click on the file wmjoyhid.inf and select Install. Then launch the WMWizard.exe application.

You may need to unplug and replug the G27 after that, but I think usually I don't have to.

(sfinktah: neither did i, in fact, i didn't even uninstall the old drivers)

It sounds like what you are describing is the same as what I was suggesting anyway. I plan to check the drift mode in the original Grid by codemasters to see how that plays.

Now - when you say "You can set to combine/not combine the throttle/brake axes." I'm assuming you're talking about some setting that can be adjusted in Logitech Profiler (5.10.127).

It's all related to the G29/clutch issue. Back to the grind stone.

I'm not even sure I can afford a real simracing seat, let alone the rest

And yeah - clutch issue = Driving Force driver [sic] issue, probably because I accidentally installed the G29 driver first.

I could live without a clutch... but I noticed this in-game, and just confirmed it on html5gamepad... the Accelerator and the Brake aren't actually separate axes, they're +/- values on the same axis!

As opposed to the break/accel xbox gamepad controls

I'm just stunned with disbelief. If this is a legitimate limitation of the G27, I'll be pulling mine apart "real soon now." I can only pray it's related to the driver/clutch glitch.

I'm planning on integrating the wheel into my drifting mod, in which one of the "cheats" is the ability to tap the brake while accelerating around a corner to increase down-force to make a tighter turn.

Also, I know you talked once on the gtamods forum about an feedback algorithm... not sure if you ever decided on one, but I now have a firmer idea of the values in the CVehicle struct, and I think you could calculate something based on the direction of travel (I'm assuming you're drifting), and the direction the wheels are pointing.

I hadn't realised this, but the value for wheel position is the actual number of degrees, expressed in radians.

The only thing I don't know, and would like to actually measure in a real car, is behaviour as the angle of travel starts to approach the maximum angle of wheel rotation. Reference the Suburu WRX which was withdrawn from Police use here because of it's tendency to go from pronounced understeer to oversteer.

@ikt said in [SCRIPT][REL]Manual Transmission & Steering Wheel Support:

@sfinktah
You need to manually assign the axes and buttons in the steering wheel setup menu.

I should probably make a first-load thing that directs users to the setting page.

LOL, I figured that since I also have a G27 too that you'd have the settings already there

oh god, apparently I'm suffering the dreaded "no clutch" issue..... (driver issues). well, that can be worked out later.

out of curiosity - has there been any consensus about the "best wheel" for PC? and has anyone every come up with a handbrake that didn't involve pulling one from a car and wiring it up?

Sorry, I'm going utterly insane here.

Logitech G27, fresh install of everything, drivers for G27 downloaded, wheel tested at html5gamepad.com (or w/e), but get this in gears.log:

I've even read the source code, but it doesn't really help. The steering wheel just isn't detected (the rest works great though).

There do appear to be set-up issues on my PC, so I tried it on a new PC (had no setup issues, profiler came up straight away, everything looked good - well, except the icon wasn't a wheel) but same (similar) message.
