Hi All,

I was just notified that the latest software version has been uploaded to the Logitech site. Here is the URL to the location. Windows XP, Vista and 7, 32 and 64 bit versions.

Logitech G940 - Software update

What's new? quite a bit. Here's the summary. Please read everything. There is a firmware update as well. It is added as a file in the Logitech folders after installation.

New features of Logitech Gaming Software 5.09

I. Adjusting force feedback settings for your game.

Games with force feedback control the forces transmitted to the G940 stick. However, you can adjust the overall level of the forces, and add a centering spring to any game.

You can adjust the levels of forces for a game by changing the settings for each game profile. This lets you customize how the controls feel for each game. When the game loads, the profile adjusts the forces automatically.
To adjust the forces, follow these steps.

1. Open Logitech Profiler
2. Select a Game profile
3. Click Menu item "Edit"
4. Click "Specific Game Settings". A window will open.

This window allows you to adjust Overall force, Spring effect and damper effect force levels. Hover the mouse over each force adjustment for a description.

Checking the "Enable Centering Spring Strength" box will turn on a centering spring, whether the game has one or not. The force of the spring can be adjusted. Note that turning the spring all the way up will mask most other forces in a game.


II. Adjusting axis response

With Logitech Gaming Software 5.09, you can now adjust the responsiveness of the 12 non-force feedback axes. This adjustment changes how sensitive the axis is to movement. To change settings:

1. Open Logitech Profiler
2. Click Menu item “Device”
3. Click “Game Controllers”. A list of installed controllers will appear
4. Click the controller you want to adjust – example: Logitech G940 Joystick
5. Click “Properties”. The Test window will appear.
6. Click “Settings”. The settings window will appear.
7. Click the button marked “Hysteresis”. (If the button is grayed-out, the G940 needs a firmware update. Click the button to go to instructions and the new firmware updater.)
8. A new window will appear. It contains sliding adjustments for each axis. They are set at default settings, but can be adjusted. A lower number indicated more responsiveness. In some games setting the number too low will cause the axis to become jittery and unstable. If this happens, adjust the number higher until the axis is stable. You can reset all the axes by clicking “Default”
9. Click OK to close the window, and close the other windows.


III. Updating the Logitech G940 Firmware

We’ve updated the firmware of the G940 to improve force feedback response, and allow for adjustability of axis response. To update your firmware to the new version, follow these instructions:

1. Close all running applications
2. Connect Flight System G940, with throttle and rudder pedals attached, to PC USB connection. Do not connect through an external USB hub.
3. Go to c:\Program Files\Logitech\FW\G940_Updater.exe
4. Double click G940_Updater.exe to start the updater. Windows 7 users should right click and choose Run as administrator.
5. The updater will erase the firmware, then wait while Windows redetects the stick, then write the new firmware. Once it it is finished, you will be prompted to press enter to close the application.
6. In some PCs the updater may freeze. If the updater freezes for more than 30 seconds. DO NOT WORRY. Close the program (click X in the upper right corner) and then restart the updater. It will complete the process.

The firmware update improves the centering response, and reduces the looseness in the center. it was also adjusted to hold the stick straighter when you take off your hand and the dead-man switch engages.


IV. Printing profiles: we improved the profile printer. The colors were changed to improve black and white printing, and command name lengths have been lengthened.


Thank you for your patience in waiting for this update.

Thanks for the update Mark!

Good news, I'll be playing with that tomorrow

Thank you for the update.

Love the adjustable axis response for the G940. That will come in very handy

Nice one, now lets wait for some reports from G940 owners. If problems are fixed I am buying the stick right away

Very nice, thanks. Giving them a try now.

Getting rid of my G940. Good job Logitech team!

Hi Mark,

I want to assign an order for Flaming Cliffs 2.0 which has an ALT-GR keystroke in it.
As soon as I hit the key an additional CTRL will be recorded.
I asked the Logitech support for a solution. They just said "install an older version".
As I expected - nothing changed.

Is there anything planned to fix this issue with the profiler-software?

Wow, terrible race tonight, blew my motor :cry:
But I wouldn't trade it for anything. I was almost ready to install this new software/firmware yesterday, but just had one of those feelings (like I said, I was more worried about my wheel than the joystick). So I decided to wait. I just now got done reading over at Logitech's forums. It seems many are not at all happy with this update for their G940's.
If you haven't already install the firmware, WAIT!
As far as I can tell, you can not go back. I feel sure they will release a rollback version, but as of now there isn't anyway to return the G940 to the prior version. I'm not talking about the 5.09 software, that of course can be uninstalled and 5.08 put back on your system. It is the Firmware that can not be rolled back at present.

Not everyone is unhappy with it, but many are. So, if you think it may be something that will not suit you, DO NOT install the firmware update. At least not until they release a rollback version, just in case.

This is a copy/paste from the thread in Hardware

TailFlamer you are Crazy. This new version works great and the Firmware is Great I am loving the Center spring know way better.

I like the why I can set up different forces in game thanks for that. In FSX and others know it is more like a joystick and it does not drupe forward as bad. Thanks Logitech_Mark I can not wait to see what is next. One question, when are you going to add a joystick combiner so the G940 and work with games that will only accept one stick with the Axes in it. not three Different units like it is know.
