Hey there

My driving force shifter doesn't reliably "hold" 5th gear. I get the feeling that there must be some "flickering" of the clutch, too, otherwise the gear wouldn't pop out in LFS, right?

Anyways, I read that this happens a lot with those shifters and it might be a calibration thing, and I also read about tools (well, rather "a" tool) that can fix it. I wanted to try that but had to find out that it wouldn't work with the G923.

Any ideas? Any third-party tweaking software for the G923 and the shifter? I can only run with G Hub, which is abysmal on several levels anyway.

Thanks.

I am not aware of any software to calibrate the shifter.
But here is a manual on how to open the G27 Shifter:

Check the potentiometer, whether is has become loose or dirty.
The text is german but there are many pictures. I think the G923 shifter is similar.

Shifting into neutral does not strictly require clutch.

The only maybe relevant tool I know of is Dxtweak.
It is popular for tweaking game controllers, setting deadzones etc. No idea if it is useful for this particular problem.

Thanks for answering.

Will probably do this once I find leisure.

Das ist vielleicht gut so... also, dass da Bilder sind.

Yeah, as a matter of fact not at all. I (re-)found that out yesterday. I thought it'd only pop out without any load, but it does instantly when pulling the stick into neutral position. That's kind of suboptimal programming, I have to say. IRL you'd have to pull like an ass to get it out of gear under load.

As for DxTweak, got that. It only handles the axes.


A little Logitech G anecdote/rant:

I started out with a G25. Rock solid, no fancy shtuff on the wheel. Shifter was included and had a sequencial-mode. Sold it for - wait for it - more than I bought it new when I hardly ever used it anymore.

Then I bought another one. "Pre-owned". Rock solid, gave me no problems. Sold that again at no loss.
At one point, I bought a used G27 (because there was no 25 around). That one had been pre-owned by a kid, obviously. From a hygienic point of view it was in a questionable condition, and the shifter looked beaten up. But it worked.

Then the wheel started to stay away from work occasionally: You plugged it in and sometimes, nothing happened. I opened it up, saw nothing I could do, put it back together and - miracle - there was no further refusal of work... until one day it died after some spastic cramps.

So finally I bought a brandnew G923, which has no shifter. I could use the G27 shifter, that isn't really supported by the G923, with a tiny workaround and at the expense of the shifter's buttons, though. One day, however, I thought I shouldn't be such a cheapskate and ordered the driving force shifter... which is obviously prone to this faulty behavior, so I'm probably going back to the beaten up G27-shifter and the workaround.

Logitech gave us less and less quality for the same price. But maybe that's ok because we have more buttons now.

The pictures are enough (atleast for me) to see the faulty part (pictures 11, 12), that usually is the culprit in any logitech shifter related issue. In most cases a cleaning and checking the wire connections to the pot should be enough, i had a wire broken off on my old G25 shifter which worked until i sold it (unfortunately though i bought mine for 210 euro and got 150 euro out of it ). From what i've heard these new shifters are somehow worse than G27, and from my experience G27 shifter is a lot sturdier than 25's due to less moving internal parts. Your shifter is still reading all the gears normally but disengaging one of them so maybe it might go away with a proper clean and checking/securing wiring.

It's not just less quality though but the shifter sold separately is probably one of the dumbest ideas Logitech came up with in my opinion, whilst keeping the wheel/pedal set at around the same prices as 27 were new. I dunno the idea behind it but the wheel sets should come with a shifter and perhaps could be sold separately alongside and maybe with a direct usb connection if people want a cheap shifter to accompany some better wheels. Oh well, can't do anything about it to be fair

I'm still rocking with the G27 as well. Funny thing is that the wheel unit failed on me so i bought another one as a spare but i've been using the pedals and shifter from the first one because they just work

I thought about these situations too, when I first tried a stick shifter. There is no good way to program it because it is a hardware limitation: The shifter can not "hold" the stick in position like in a real car.
The alternative would be that virtual stick and real stick go out of sync.

I do not like that either. Fanatec does the same thing, their shifter only works when connected to a wheel-base. Depending which wheel you use, you need the right adapter.

The Logitech shifter can be used stand-alone with a small Arduino project:


...or buy it as finished product:

This part sounds interesting:

Gear position sensors can be calibrated in our easy to use software.
Switching thresholds can be adjusted with our software and permanently stored inside the device.
Especially useful for shifters with old worn gaitors.

Why can Logitech not just include such option in their software? Maybe they are afraid of people using it wrong.

Also it seems many parts can be found as files for 3D printing.
For example this part for the switching lanes/gates that hold the stick in position:
