Update 2022-12-16: I upgraded to a Simucube 2 Pro in April of 2021. I enjoyed the SimXperience AccuForce Pro and it’s a fine wheel but after 5 solid years I decided to try something new. If you’re considering an AccuForce Pro I’d still highly recommend it. Find out more on Secrets of the Simucube 2 Pro.

Update 2021-02-12: Added Games > Kart Kraft section with Force Feedback settings.

Update 2021-02-12 (2): Added AccuForce Duramold Steering Wheel review. A good, cheap replacement wheel for the stock Leather or Alcantara for when it wears out.

Update 2021-01-01: Added Games > Assetto Corsa Competizione > Reducing Weird FFB Tick in Scrubs/Slides.

What is the SimXperience AccuForce Pro?

The AccuForce Pro is a force feedback steering wheel system used mainly for sim racing on PC.

From the SimXperience website,

The AccuForce Pro V2 Steering System Kit is a complete Plug-N-Play package of our most advanced and realistic direct drive force feedback system. With unparalleled realism and the most advanced tuning features on the market, the AccuForce Pro not only delivers significant advantages for hardcore sim racers but is an effective training tool for real world drivers as well.

Here’s a taste of what it is and how it plays in games, from Inside Sim Racing and their short review,

Getting Started

In Secrets, I try to focus on the non-obvious or unintuitive so I won’t be covering basics like getting the wheel or installing it, unless there is is something of note to comment on. You’re probably beyond that yourself so I’ll focus on the more obscure and non-obvious things.

My Initial Review

You can find my initial unboxing, review, and various notes over at my post titled SimXperience AccuForce Pro Steering System.

SimXperience SimCommander

First, go to the SimXperience AccuForce Pro product page and then click the Documents / Requirements tab and you will be presented with a number of guides and tutorials, both written and video. These are worth a watch at least once.

AccuForce Settings For Dummies

If you want to dive in and tune your SimCommander game profiles but don’t quite understand the available sliders and options, check out MockRacer.com’s AccuForce Settings For Dummies. It’s a good introduction to what is going on in SimCommander for AccuForce options.

Reset Game Profile to Defaults

1. Duplicate Profile
   1. Open the Control Center, select a profile, then click the Duplicate button near the top of the window.
2. Reset Profile to Defaults
   1. Open the Control Center, select a profile, click Output Mixer tab in the middle portion of the screen, click the Output Tuning Wizard button in the same area, select Reset To Defaults option, click Next, Click Next again, click Finish.

And, my typical custom defaults:

1. Set Wheel Mode High
   1. Set Wheel Mode “High” in Output Mixer > AccuForce Steering Wheel > Device Settings.
2. Disable Engine RPMs

How to Auto-Tune In SimCommander

Auto-tuning automagically adjusts the force feedback strength based on recorded lap telemetry ensuring you have the greatest strength at the wheel while avoiding clipping.

Here’s how to do it:

1. Duplicate Profile
   1. Duplicate an existing iRacing profile in Sim Commander: Open the Control Center, select a profile, then click the Duplicate button near the top of the window.
2. Reset Profile to Defaults
   1. Reset the profile to defaults so you’re sure you’ve got a good base line: Open the Control Center, select a profile, click Output Mixer tab in the middle portion of the screen, click the Output Tuning Wizard button in the same area, select Reset To Defaults option, click Next, Click Next again, click Finish.
3. Reset Wheel Mode
   1. Set your desired Wheel Mode in Output Mixer > AccuForce Steering Wheel > Device Settings. I use High as, according to SimXperience, it’s the only guaranteed linear force feedback. You can use whatever you’re comfortable with. The important thing is that you do this before running laps or else it won’t correct if you change the Wheel Mode after.
4. Run Laps
   1. Launch your game using Sim Commander with the overlay enabled and run a few laps at your favourite track. These laps will be recorded and you’ll pick the fastest in Sim Commander so it can tune your settings for that track and car.
5. Auto-Tune Profile
   1. Open the Control Center, select a profile, click Output Mixer tab in the middle portion of the screen, click the Output Tuning Wizard button in the same area, select “Create effect settings from recorded lap  telemetry” option, click Next, Click Next again, select your fastest lap at the track you just ran laps on, under the “Select a Template” heading choose “Intelligent Peaks” in the drop-down, click Next, click Finish.

Smoothing (0-255)

• This and Device Settings > Overall Smoothing are one and the same and if you change one it changes the other.
• The Device Settings option only goes up to 47.06% while the other goes up to 100% (255).

Intensity (0-100%)

• This and Device Settings > Overall Intensity are one and the same and if you change one it changes the other.

AccuForce Duramold Steering Wheel

This wheel is better than it looks and better than its price would make you think.

When my Alcantara wheel material started to wear down and slick from use, I picked up this wheel thinking it would be a poor, plasticky feeling wheel, but it’s not. I actually think it should probably be the default wheel.

It is cheaper in make and quality than the other stock options, yes, but for what it is it’s actually really good. The DuraMold material is tough but still has a nice rubbery give to it when pressed. There’s red highlight stitching that only serves to make it look a little nicer. The wheel is smaller than the stock wheels which means your fingers can reach the buttons more easily.

Honestly, I thought I was getting a downgrade because I just needed a wheel, but I have to say this thing is good.

Basically a super well-done launcher for Assetto Corsa. Free to try, lots of options available free, and absolutely worth it to unlock for a donation of any amount (as of 2019-05-21).

Reducing Weird FFB Tick in Scrubs/Slides

Try lower Force Feedback Frequencies in Options > Controls to lessen or remove that weird ffb tick during scrubbing / slides. There’s no option to disable this effect specifically.

The tick never felt right to me. I assume it’s meant to communicate rubber sliding laterally over tarmac but the effect just throws me off.

At 111hz the effect is pretty much disabled as far as I can tell and I found the experience of scrubbing or lateral slides then started to match my experience in other sims – which to me is preferable at this point.

At 222hz the effect is almost gone but there is something there and it may be more helpful than at 333hz. Try it out for yourself.

At 333hz the effect is in full force and it feels like a quick, sharp but light, tick in the wheel that I can’t quite make my brain turn into useful information.

Lowering the Frequency doesn’t seem to have a dramatic effect on FFB quality. iRacing still gets away with 60hz so 111hz isn’t a bad jump.

See Frequency under Force Feedback here:

irFFB – Alternative Force Feedback

GamerMuscle’s recent irffb video got me interested in trying irFFB particularly for the SoP (Seat of Pants) feel. I call this SoP feel “Oversteer Effect” as it seems to me to complement the Understeer Effect you can also find in irFFB, Assetto Corsa, etc.

Click here to download vJoy 2.1.8 prerequisite for irFFB

Click here to download irFFB 1.4.2 (latest as of 2020-10-19)

The way GamerMuscle says it, some slides you just can’t catch in iRacing, you don’t feel it coming on and once it hits that’s it it’s going to slide out on you and there’s no way to recover. He says with irFFB + SoP he can catch rear end slides much more easily.

Here’s my irffb settings:

SimCommander’s Rear Traction Loss effect comes into this because it basically accomplishes the same thing as irFFB SoP but, I would say, with a more elegant feel.

I’m currently using 12-25% Rear Traction Loss to mimick 12-25% irFFB SoP.

I recommend giving either of these a try.

PS. irFFB might be a replacement for SimCommander for some people because (a) it works right out of the box, (b) it’s simple one-page interface, and (c) it provides some of the typical ffb tuning parameters built right in that you might have seen in other games.

Project Cars 2

First, this SimXperience video does a good job explaining how to initially setup the game:

Project Cars 2 does not detect steering left/right assignment

Mentioned in the video but I found that you, at least, need to rotate the wheel 360degs in the direction of the assignmnet, and then back again 360degs, to get Project Cars 2 to detect the assignment.

Project Cars2 may act like it never detects any steering assignments or it complains about ‘multiple inputs detected’. The rotation fix mentioned above fixed this for me.

Unexpected/Unnatural Rotation/Oversteer In Corners on Throttle Lift-off

If you experience unexpected/unnatural rotation-around-center /oversteer in corners when you lift-off the throttle then try going Tuning Setup > Edit Setup > ECU/Engine/Gearing > Engine Braking and increasing that number.

Engine Braking: Lower values result in greater engine braking torque which can cause the wheels to rotate too slowly or lock-up when you lift off the throttle in corners and this can cause the car to rotate/oversteer more than you think it should.

So, try increasing Engine Braking to counteract this problem.

Improved FFB with Jack Spade Custom FFB Files

 I no longer use Jack Spade files or ffb settings. See Christiaan or SFF settings, above.

See this post in the Project Cars 2 forums for custom FFB files. I found it difficult to get satisfactory FFB out of Project Cars 2 so I went asking around if any other AccuForce owners have good results and a user told me about the Jack Spade files.

Current Settings: Test 8.3 (below)

Tips and Tricks

Heavy wheel or heavy dampening feel when driving

Try disabling Stationary and Moving Dynamic Oscillation Control. Some games or configurations have been known to trigger a heavy wheel feeling even when it shouldn’t (eg. Stationary Dynamic Oscillation Control enabled but car is moving so it shouldn’t be taking effect) so try disabling oscillation control.

Try tuning oscillation control levels yourself, after confirming the issue with disabling, to dial in the feel that you want.
