Split brake axis via UCR and vjoy

[das_a]

Dear fellow flyers,

first of all, let me start by saying that this forum seems to be one of the nicer ones, where answers not only consist of "rtfm" or "use the search function".

Now, to the problem at hand:

I mainly fly the P51D. For that i use a T.HotasX for stick & throttle and i'm currently in the process of building rudder pedals/brakes out of an older Logitech racing wheel. The wheel portion will be the rudder axis and the pedals are for the individual wheel brakes.

The pedals on said input device are on a single axis. So I installed UCR and vjoy to split them into two axises. I bound them to the respecting wheel brakes in the mustang's contoller settings and started to taxi. Worked fine so far.

But: When I depress both pedals (to brake in a straight line) instead of increasing the value of both vjoy axises, it decreases the original axis of the (hardware) pedals to -100, so it doesn't brake at all.

Hopefully it's just a simple fix which is already solved and posted somewhere else here. If so, I'd be happy to be redirected there. If not please feel free to ask any questions you might have.

So far thanks for reading, I'll be looking forward to any suggestions from you.

That seems quite unusual for race pedals to be on a combined axis. What Logitech model is it?

Ah, Baldrick. Thought you might come up with a cunning plan. (Sorry , couldn't resist.)

No name on the outside, it just says Logitech Racing Wheel in Window's Controller Settings. Really old one, probably early 2000's. The pedals aren't connected directly via usb but through the wheel casing by a 9-pin sub-d connector.

Looks like this:

 

Seems to be sometimes branded as Logitech Nascar.

Do you have any software for it that could choose the mode - combined or split?

I don't see how a single axis split into two would work. They could work independently but not together. I have used UCR to do the opposite - convert race pedals to a single axis for use as a rudder.

Your pedals should work fine as a rudder though!

No, a software from Logitech to do that would be the ideal solution, but i'm not aware of anything like that. It was cheap back in the day, maybe 50 euros, so I don't think Logitech would have provided such a solution. I actually use the pedals as rudder for now but there I have a similar problem: When I depress, say, the right pedal and then the left but forget to release the right one, it just decreases the deflection to the right. That's why I want to custom build a rudder pedal set from the steering wheel as there it is alrady mechanical impossible to use the axis in both directions at the same time. Hope that makes sense. And the pedals then come on top for the brakes. Somewhat like it is irl.

[Baldrick33]

It does make sense. I think that may have been a Playstation 2 controller?

The only thing I can think to do is set a modifier to switch between the right pedal being the right brake and it being the (only) wheel brake so it applies equally to both brakes. Then you could use either left or right separately for manoeuvring and press the modifier and use the right brake to apply both brakes.

[das_a]

Yes, I thought of that too, but that's only half a solution. My current workaround is a button on my stick for both brakes which of course leads to the occasional ground loop. Doesn't make my crew chief happy, though. I tried to fiddle with UCR's various filters plugins so far but nothing seems to help. I've read in other post from you that you are using Joypro. I installed that also but so far i didn't manage to find a solution to that particular problem there.

You could try this and see if you can split the pedals axis

Thanks a whole lot for the effort, but the driver refuses to be installed on a 64 bit OS. Maybe it's even older than I thought it was, lol.

[Baldrick33]

This is a version that might work with more modern OS

As much as I appreciate your effort: No, it doesn't. Seems to be the same software, at least the file name is exactly the same. (lgs460enu.exe)

I had a Logitech G25 15 or so years ago which I used for about eight years, the driver name sounded familiar and it was updated to work with 64 bit OS and supported all the old devices in one exe, so I was hopeful! 

Edit: This was the file I last used, no idea if it will support your wheel but maybe worth a try

Ah Baldrick! Always the humble servant.

That did the trick! Guess I have to include you in my last will now. Not that there will be much though...

[Baldrick33]

Great that it is working!

Must go, I have some war poetry to write. Boom, boom, boom, boom...
