Get started

From nothing to your own dashes and lights, one step at a time. Every step says what you should see, and what to do if you don't.

This guide takes you from nothing to custom dashes and lights on your FX Pro, one step at a time. Every step says what you should see, and what to do if you don't. It's the same guide as on fxunleashed.com/start.

FX Unleashed is an independent community project. It is not affiliated with, endorsed by or supported by Simagic. Simagic and FX Pro are trademarks of their owner, used only to say which hardware this works with. The software is provided "as is", without warranty of any kind. Use it at your own risk.

Two ways to use it. Standard mode needs nothing flashed: the rev lights follow each car and the wheel switches to each car's dash, through SimPro. Unleashed mode is everything else in this guide (your own dashes, all 38 lights, screensavers, the dash button) and needs modified wheel firmware. If you only want standard mode, do steps 1, 2 and 8.

#1. What you need

• A Simagic FX Pro wheel on a Simagic base (tested: Alpha EVO), wheel app 1.3.11 (SimPro shows it).
• SimPro Manager 3 (tested: 3.2.2) and SimHub (tested: 9.11; the free version is fine).
• The wheel's USB cable, and for the best setup a data-only adapter (a USB adapter that blocks the 5 V line), or a USB hub port with its power switch off. See step 4 for why.
• Windows 10 or 11.

#2. Install the plugin

1. Close SimHub.
2. Download the latest release from the releases page (the newest is on top; the zip is under Assets) and unzip it.
3. Copy User.FXProRpmSync.dll into SimHub's folder (usually C:\Program Files (x86)\SimHub\).
4. Start SimHub. It asks whether to enable the new plugin: say yes.

You should see "FX Unleashed" in SimHub's left menu. If not: Settings > Plugins, tick FX Unleashed, restart SimHub. If Windows blocked the file, right-click the DLL > Properties > Unblock, then restart SimHub.

From now on the plugin updates itself: a blue banner appears when there's a new version, and one click installs it (About tab). You can always roll back to the previous version there.

#3. Before you flash: the risks

Unleashed mode needs a modified version of the wheel's own app. Read this before going on:

Installing modified firmware on your wheel is at your own risk.

• It isn't made, tested or supported by Simagic, and it may void your warranty.
• A bug, an interrupted install or a difference in your hardware could stop the wheel from working correctly. In rare cases you might not be able to recover it yourself.
• We check every build (every change emulated against the stock firmware, then tested on a real wheel), but we can't test every wheel, base, revision and setup.
• It only changes the wheel's own app (lights, screen, buttons, USB). It doesn't change your base or force feedback. You can go back to Simagic's stock firmware with SimPro at any time (step 10).
• Don't unplug or power off the wheel while it installs.

To the extent the law allows, the authors aren't liable for damage to your hardware or any other loss.

#Install the firmware

Status: how the modified firmware is handed out is still being decided (it must never include Simagic's own firmware file or its key). The plan is a Firmware card in the plugin that builds the modified file from your own SimPro copy, checks it by checksum, and walks you through the steps below. Until then, the project shares builds directly with testers.

The firmware goes on through SimPro's own "reinstall firmware" button:

1. The wheel on USB (cable in, base on). Check SimPro's copy of the wheel app is the original (the card will do this by checksum).
2. Put the modified file in its place (same file name, in SimPro's firmware\wheel\fx_pro folder), then in SimPro reinstall wheel app 1.3.11 (Device > FX Pro > Firmware).
3. Wait for SimPro to finish. Don't unplug anything. If SimPro hangs after the wheel enters boot mode, close SimPro and start it again: it installs to a wheel that's already in boot mode.
4. Put SimPro's original file back right away, so no later update installs the modified one by accident.

You should see the wheel restart normally. On the plugin's Wheel tab (step 6) it shows "patch build 7" (or newer).

#4. Wiring and power

• The base powers the wheel. The USB cable should carry data only: a 5 V-blocking USB adapter, or a hub port whose power switch is off (it cuts only the 5 V; data still flows).
• At start-up: turn the base on. The wheel starts on the base; about 3 seconds later it notices the PC on its cable and restarts into USB mode. The plugin waits 6 seconds for it to finish starting, then takes over when a game runs.
• Avoid: plugging the cable into a wheel on a base that is switched off. The cable's 5 V then also feeds the base through the quick release: the wheel can turn on and off and come up with a garbled screen. With a data-only cable this can't happen. If it happens anyway: base off, cable out, wait, start again.

You should see the Wheel tab's status go "Wheel on the base" > "Restarting into USB mode" > "Ready".

#5. Game controls

In USB mode, the wheel's buttons and paddles reach the PC only through the wheel's own USB controller ("FX Pro"), not through the base. So in each game, bind your wheel buttons and paddles once to that controller:

Steering, pedals and force feedback stay on the base as before: nothing changes there.

The dash button is button 40. Some games only list 32 buttons; bind it to a plugin action instead (Wheel tab > Quick controls > Wheel buttons), e.g. "Next dash".

#6. Turn on Unleashed mode

1. SimHub > FX Unleashed > click the Unleashed card. Read the warning and confirm.
2. Wheel tab: the status should say Ready, and the wheel line "patch build 7".
3. Press Run the demo: a demo lap plays on the wheel with a custom dash and lights. Press it again to stop.

If the status says "Firmware not confirmed": your wheel runs an older patch (builds 4-6) that can't report itself. Press Test on the wheel (8 s): if the demo dash stays steady, tick "My wheel runs the patched firmware". If the wheel's own dash flickers through it, the wheel runs stock firmware (harmless; go back to step 3).

#7. Dashes

• Per car: Dashes tab > pick a car (or the default list) > add dashes. The first one shows when the car loads; the dash button (or a key) steps through the list while driving.
• The wheel's own dashes work too: the plugin switches to them and feeds them SimHub's data over USB.
• Library: Dashes tab > Library > Browse. Install one in a click, then "Use for this car". No restart.
• Your own: "Edit in the designer" opens the dash designer in your browser. When it's done, "Package for the library" gets it ready to share.
• Stream it: Dashes tab > Stream the wheel's screen: an OBS browser source with the screen and the lights.

#8. Lights

• Presets: Lights tab: pick a preset, or make your own in the editor (per group: rev lights, side lights, buttons, encoders). Presets can be set per car and per game.
• Rev lights follow each car's real shift lights where the data exists (Lovely Car Data).
• Alerts: flags, spotter, pit limiter, ABS/TC, low fuel and more, in the order you choose; add your own from any SimHub property or formula.
• Encoders show their setting (ABS, TC, bias, map, diff), and buttons can light up while pressed.
• Other sources: ATSR-Hub, or any SimHub LED profile (add "FX Pro wheel (USB mode)" in SimHub > Devices, then Lights tab > "SimHub device").
• Brightness: Wheel tab > Quick controls: a ceiling for every light, and night mode (dimmer screen and lights, on a schedule or with ATSR-Hub's night mode).

In standard mode, the rev lights still follow each car, through SimPro.

#9. Idle and sleep

• Screensavers between sessions: the logo, a clock, start lights, your last session, a picture of your own, or one from the library (Idle & sleep tab > Library).
• Sleep: after a while with no game, the screen and lights go off; they wake when a game starts.

#10. Updating, and going back to stock

• Plugin: the banner offers new versions; one click installs; Roll back is on the About tab.
• Firmware: a newer build goes on the same way as the first (step 3). The Wheel tab shows which build the wheel runs.
• Back to stock: with SimPro's original file in place (it always is after step 3), reinstall wheel app 1.3.11 in SimPro. That's Simagic's own firmware again. Reinstalling firmware always carries a small risk: don't unplug the wheel while it installs.
