Sound Shift for iRacing is software that provides audio cues for gear selection, brake force and rev limit. All can be adjusted and even muted if you don't want all cues. This service contains its own Sound Shift files for iRacing users to download and use for their installation. Especially useful when new cars enter the service.

What Is Force Feedback

Update 2015-02-26: I’ve been changing up my FFB settings in iRacing lately after realizing that linear ffb resulted in such low force strengths (to avoid clipping) that I wasn’t really feeling the road anymore. The ffb changes were just too subtle. So, because I have a low-end wheel, a G27, I’m now using non-linear ffb and doing the usual binary-search to find the optimal force strength to avoid clipping. I’m doing this only because of my relatively low-end, entry-level G27. I expect the recommended usage for higher strength wheels (T500s/T300s, Fanatec ClubSports, Accuforce Pro, etc.) should still use linear ffb.

Update 2015-02-26 – 2: For the record, a binary search is one where you take your current value, determine whether it’s too little or too much, and then double it (when too little) or halve it (when too much), and repeat that process at each new level to dial in on your optimal value. For example, for iRacing force strengths I might start out at 32, decide that’s too much and go to 16 (half of 32), decide that’s too little and go to 24 (16 + 8 which is half of 16), decide that’s too much and go to 20 (24 – 4 which is half of 8), decide that’s too little and go to 22 (20 + 2 which is half of 4), decide that’s too little and go to 23 (22 + 1 which is half of 2), decide that’s too much and go to 22.5 (22 – 0.5 which is half of 1). This is a real example I just did in iRacing a few minutes ago on the Mazda MX-5.

Update 2015-02-26 – 3: Nvidia users should check out these threads: iRacing graphic optimizations for NVIDIA users, Guide: nVidia iRacing Antialiasing (AA) Settings, NVIDIA SLI Compatibility results. The second guide about AA gives some good settings for Nvidia Inspector (I use in-game 4x AA with Nvidia Inspector AA – Mode “Enhance” and AA – Setting “8xS [Combined: 1×2 SS + 4 MS]”. Read the thread for what they mean). The third thread is about SLI and getting rid of microstuttering (I use Nvidia Inspector “SLI Compatibility Bits” = “0x00402015” per the thread). It’s not perfect but it’s better than in-game AA and should give higher performance.

I’m a big fan of iRacing sim racing and I frequent their forums quite a bit. I’ve seen a number of posts, over time, on the iRacing forums about people asking for the right force feedback settings for their wheels. As it turns out, this info in its complete form is harder to come by then you might think so I’ve decided to post everything I know and have implemented for my Logitech G27 for force feedback in iRacing…

1. CrewChief is awesome. CrewChief is an all-in-one race management tool which allows you to set up tactics, get race information, lap times, and a bunch of other things over the radio, even allowing you to communicate back. It also doubles as a greatly improved spotter when compared to the default iRacing.
2. Download this app from Microsoft Store for Windows 10, Windows 10 Mobile, Windows 10 Team (Surface Hub), Xbox One. See screenshots, read the latest.
3. Loading a test session is easy – simply click on “Test” here, and select your car and track here. When you’re ready, hit “Test Car on Track”. This will load up the sim for the first time. Click Auto Configure and iRacing will give you the best optimal graphics settings possible for your system.

David Tucker, staff at iRacing.com, worked on the Logitech G27 force feedback and he indicates they put a lot of effort into making the G27 “optimal” out of the box:

I recommend the defaults in the driver (100% for everything) and 900 deg of rotation. It use to be the case that you needed to mess with the driver but a long time ago I made sure that the defaults in the driver would be optimal.

In addition to everything default in the profiler, in-game I use linear force feedback, which is supposedly technically more accurate feedback, a Min Force of 16.6% (this number is very close to every other G27’s calculated Min Force so it should work for you), Strength 32 (for a Mazda MX-5 Cup but it depends on the car, my Lotus 79 and Ruf use 20), and Damping 0% (because I want my feedback sharp not dulled).

We’re almost done but there’s one more tiny thing we need to do that made a world of difference for my force feedback:

“I hate the chatter but I really wanted to feel the road and straights are the best indicator around the center to tell if you’re actually feeling everything.” -Matt

In your case you may want to go back to the old min force method….You can go back to the old method by setting app.ini [Force Feedback] FFBUseSimpleMinForce=1 -David Tucker

You should be able to find the app.ini file in your Documents folder under the iRacing folder. For example, my app.ini is here: C:UsersMattDocumentsiRacingapp.ini

Copy and paste that file to make a backup copy in case you want to go back. Then open it in notepad and find the line that starts with “FFBUseSimpleMinForce=0” and change it to: FFBUseSimpleMinForce=1

A note on fine tuning strength in-game: Hit the F key while driving to get the force meter up. It’s the green/orange/red meter that’s always going up and down according to your wheel’s current strength output. To get optimal strength and detail out of your wheel start with a low strength and keep increasing it. You will notice your force meter hitting red more and more often as you drive – red means maximum output and it means the game wants to output more but your wheel can’t handle it (you’re losing feedback detail at this point which is not good, it’s called “clipping”). Keep increasing your force strength until the force meter only flashes red (clipping) for split seconds in your sharpest cornering. This will be your optimal force strength for your wheel.

Enjoy!

PS. You might find my post on force feedback settings for Sector 3 Studio’s RaceRoom Racing Experience informative as well!

SimConnect Log file

If you are experiencing problems using FS Force, you may be asked by technical support to provide a copy of your SimConnect log file to help diagnose the problem. This log file is not produced by default. Follow these steps to configure your system to produce a SimConnect log file.

1. Create a text file using a simple text editor like Notepad, and name it SimConnect.ini. Place it in the special flight simulator sub-folder beneath your Documents folder. Depending on which flight sim version you are using, this sub-folder will either be called Flight Simulator X Files, Flight Simulator X - Steam Edition Files, Prepar3D v3 Files, or. Flight Sim World. (If you already have a file by that name in the sub-folder, open it in your editor instead of creating a new one).

2. Edit the file so it contains the text shown below. The file= line can be customized to point to any folder that is convenient for you.

[SimConnect]
level=verbose
console=0
file=C:simconnect.log

3. Save the file, and then start FSX. Use a watch or a stop-watch, and count the number of seconds that elapse from the time you start FSX.

4. Start a flight and do whatever you need to do to reproduce the errors you are experiencing. As soon as the error has occurred, take note of the number of elapsed seconds, and then shut down FSX

5. Send the resulting SimConnect.log file to the support email address above, along with your report of when the error occurred.

6. Once the issue has been resolved and you no longer need logging enabled, you can either delete the SimConnect.ini file, or place a semi-colon (;) at the beginning of the file= line to disable logging.
   

Customer Feedback

Just a quick note of thanks for this amazing little piece of software. The thing works, and how!! I have a MS FF2 that was a spastic, limp, lump of plastic until now. The customer support is incredible - my wife deleted my activation code, and it was re-sent within minutes of my requesting a duplicate. Amazing. Software that works, first time ... good customer support...

FS Force Log File

FS Force can also be configured to produce it's own log file. Follow these steps :

1. Locate the file FSForce.cfg. Under WinXP, this file can be found under 'C:Documents & SettingsAll UsersApplication DataFS Force'. Under Vista, it can be found under 'C:ProgramDataFS Force'.

2. Open this file using any text editor. Under the [General] section add 'Errorlevel=1'. (Setting it to 0 turns logging off.). The log file is saved in the same folder as FSForce.cfg.

Force Feedback Diagnostic Program

Iracing Test Pc

This is a small utility program you can download to test the force feedback capabilities of your joystick. If FS Force doesn't seem to be working properly, you can use this utility to test your joystick, which can be helpful in determining if the problem is with FS Force, your system, or your joystick.
