Have I received the DX Winner 2 or the DX2 Ultra?

The DX2 Ultra was previously known as the DX Winner 2. Some packaging, files, firmware references or older community material may still use the DX Winner 2 name. This is normal and does not mean you have received the wrong product.

For clarity:

  • DX Winner 2 = DX2 Ultra
  • The newer name is DX2 Ultra
  • Older instructions, Discord posts, videos and files may still say DX Winner 2

If you are unsure, please send us a photo of the label/packaging and we’ll confirm it for you.

Which fixings, bolts and T-nuts do I need?

The supplied fixings are intended to cover common installation scenarios, but not every aluminium profile rig uses the same bolt and T-nut sizes.

Before installation, please check:

  • Your rig profile size: for example 40x40, 40x80, 40x120, 40x160
  • The T-nut size used by your rig
  • Whether your seat rails line up directly or need adapter/profile bars
  • Whether your rig uses M5, M6 or M8 hardware

Some aluminium profile rigs may require additional T-nuts, bolts or adapter fixings. If you are unsure, send us photos of your rig, seat rails and mounting area before drilling or modifying anything.

Important: Do not drill, grind or modify brackets unless you are confident it is safe and necessary. Contact us first and we’ll help you check the best mounting approach.

Safety and clearance checks

Before using the DX2 Ultra, please check that the unit is securely fitted and has enough space to move freely. The platform moves the seat in pitch and roll, so it is important to make sure nothing can touch, catch or restrict the seat during operation.

Before your first proper session, check:

  • All bolts, brackets and seat rails are securely tightened
  • The seat is centred and firmly mounted
  • There is clearance around the seat shoulders, side bolsters and rear of the seat
  • Shifters, handbrakes, button boxes and rig side profiles are not in the path of movement
  • Power and USB cables are routed safely and cannot be pulled, trapped or pinched
  • Nothing loose is stored under or around the moving platform
  • Your rig is stable and sitting securely on the floor

After installation, we recommend running a low-intensity motion test in SimHub while watching the seat from the side and rear. Start gently, confirm that nothing touches, and only increase motion strength once you are happy that the setup is secure.

If you hear unusual clunking, scraping or knocking, stop using the unit and check the installation before continuing. If you are unsure, send us photos or a short video of your setup and we’ll be happy to help.

Installation & Fitment

Where are the fitting instructions?

You can find the latest DX2 Ultra fitting instructions on our support page under:

DX2 Ultra User Guide

We recommend reading the full guide before starting, especially the sections on:

  • Mounting the platform to your rig
  • Seat rail/profile alignment
  • USB and power connection order
  • SimHub setup
  • Motion profile configuration

The DX2 Ultra is compatible with many rigs, but sim rigs vary a lot, so some setups may require careful positioning or additional fixings.

My seat rails don’t line up with the platform. What should I do?

Seat rail spacing varies between seats and rigs, so some seats will not bolt directly to the DX2 Ultra without adjustment.

Common solutions include:

  • Using the supplied aluminium profile bars as an adapter between the DX2 Ultra and your seat rails
  • Mounting seat rails to profile first, then mounting the profile to the DX2 Ultra
  • Checking that the seat can move freely without hitting the rig, shifter, handbrake, wheelbase or side profiles
  • Using low-profile bolts where space under the seat is tight

Before fully tightening everything, do a dry-fit and check:

  • The seat is centred
  • All bolts can be accessed
  • There is clearance for full motion
  • Cables are clear of moving parts
  • Nothing touches the rig during pitch/roll movement

If in doubt, send us photos before final tightening.

How much clearance does the seat need around it?

The DX2 Ultra moves the seat in pitch and roll, so you need clearance around the seat, especially:

  • Around the shoulders
  • Around side bolsters
  • Near shifters and handbrakes
  • Behind the seat
  • Around seat belt tensioner brackets, if fitted

Before racing, run a low-intensity motion test and watch the seat from the side and rear to confirm nothing touches.

If you use a wide bucket seat, high shoulder bolsters, button boxes, shifters or belt tensioners, allow extra space.

Should I update the firmware?

Only update firmware when instructed by SimScapers or DynamicX support, or when a firmware file is clearly marked as the latest official release for your model.

Before updating firmware:

Confirm the file is for the DX2 Ultra
Read the update instructions fully
Do not disconnect power or USB during the update
Keep a note of the current firmware version if shown
Contact us if you are unsure

If a firmware update fails or the unit does not start afterwards, contact support before trying further updates.

Is the motor/PSU/fan noise normal?

Some sound is normal. You may hear:

Motor noise under load
Fan noise
Power supply hum or high-pitched electrical noise
Mechanical sound during sharper motion events

Most users find the sound acceptable during racing, especially with headphones or VR audio.

Contact us if you hear:

Loud grinding
Repeated metallic clunking
Sudden new noises
Sounds that happen even when the platform is not moving
A loose component sound inside the unit

A short video is the best way for us to judge whether the sound is normal.

Can I use the rig when the DX2 Ultra is powered off?

The DX2 Ultra does not have a mechanical brake or lock when powered off. This means the seat may move when the unit is switched off.

If you want to use your sim rig as a static seat for long non-driving sessions, you may need a removable support or brace. Any support must be removed before switching the motion system back on.

When powered on and idle, the seat will generally feel more stable, but the unit is still powered and fans/noise may be present.

Can I use belt tensioners with the DX2 Ultra?

Belt tensioners may be possible, but they require careful consideration.

Before fitting belt tensioners, check:

Total user + seat + accessory weight
Where the belt tensioner mounts
Whether the bracket moves with the seat or stays fixed to the rig
Whether the belt path interferes with seat motion
Whether extra brackets add load or leverage to the platform
Whether the system remains within safe operating limits

Please contact us before fitting heavy belt tensioners directly to the DX2 Ultra or its moving structure.

For many users, a passive belt setup may be sufficient because the seat movement already creates a strong sensation under braking and acceleration.

SimHub Setup

Do I need a SimHub licence?

Yes. To use and properly test the DX2 Ultra with SimHub, you may need the relevant SimHub licences, including the motion add-on/licence.

Without the correct licence, you may experience limits such as:

Short test time
Motion stopping after a few minutes
Inability to properly test motion output
Missing or restricted motion features

If the platform stops after a short period during testing, please check your SimHub licence status before assuming there is a hardware fault.

Which SimHub files do I need?

You will need the DX2 Ultra / DynamicX SimHub configuration files from our support page.

Please download:

  • The DX2 Ultra SimHub profile/configuration files
  • Any required driver files
  • The latest firmware file, if instructed by support
  • The setup guide showing how to import the files into SimHub

If SimHub does not show DynamicX/DX2 Ultra automatically, this does not necessarily mean there is a fault. You may need to manually import the correct geometry/profile files.

If you cannot find or import the files, contact us and we’ll send the correct files directly.

SimHub feels complicated. Is that normal?

SimHub is powerful, but it can feel complex if you have not used it before. The DX2 Ultra is not just a plug-in USB accessory - it is a motion platform, so correct setup matters.

You may need to configure:

Motion output
Platform geometry/profile
COM port/USB connection
Axis direction
Pitch and roll settings
Game-specific tuning
Motion intensity and smoothing

We recommend starting with our suggested beginner profile before changing advanced settings.

Can I reduce the amount of movement?

Yes. In SimHub you can adjust motion intensity, speed, smoothing and range.

For first setup, we recommend:

Start with low intensity
Test pitch and roll separately
Increase motion gradually
Avoid extreme settings until the rig is fully secure
Use smoother settings for longer sessions, VR, or late-night use

More movement is not always better. Many sim racers prefer subtle, well-tuned motion for realism and consistency.

Troubleshooting

The DX2 Ultra has raised my seating position. Is that normal?

Yes, adding a motion platform will usually raise your seating position. Depending on your rig and seat mounting method, you may need to adjust:

Wheelbase height
Pedal position
Monitor height
Shifter/handbrake position
Seat distance from pedals

We recommend completing the DX2 Ultra installation first, then re-setting your driving position using your normal sim racing ergonomics.

My seat rails don’t line up with the platform. What should I do?

Seat rail spacing varies between seats and rigs, so some seats will not bolt directly to the DX2 Ultra without adjustment.

Common solutions include:

  • Using the supplied aluminium profile bars as an adapter between the DX2 Ultra and your seat rails
  • Mounting seat rails to profile first, then mounting the profile to the DX2 Ultra
  • Checking that the seat can move freely without hitting the rig, shifter, handbrake, wheelbase or side profiles
  • Using low-profile bolts where space under the seat is tight

Before fully tightening everything, do a dry-fit and check:

  • The seat is centred
  • All bolts can be accessed
  • There is clearance for full motion
  • Cables are clear of moving parts
  • Nothing touches the rig during pitch/roll movement

If in doubt, send us photos before final tightening.

The motion is reversed / the seat moves the wrong way. What do I do?

If the seat appears to move the wrong way, this is usually a SimHub configuration issue rather than a hardware fault.

Check:

Axis direction in SimHub
Left/right roll direction
Pitch direction
Whether “lean inwards” or “lean outwards” behaviour is selected
That the correct DX2 Ultra profile/geometry has been imported

Use SimHub’s motion test tools at low intensity first. If left and right are reversed, swap or invert the relevant axis in SimHub.

The unit powers on but doesn’t move in-game

If the DX2 Ultra powers on but does not move in-game, please check the following before assuming a fault:

Is the DX2 Ultra connected by USB?
Is the correct COM port selected in SimHub?
Have you imported the DX2 Ultra / DynamicX SimHub files?
Do you have the required SimHub motion licence?
Does SimHub detect the game telemetry?
Does the platform move in SimHub’s test mode?
Have you restarted SimHub and your PC?
Have you fully powered down the DX2 Ultra and powered it back on in the correct order?

If it moves in SimHub test mode but not in-game, the issue is usually software/profile/telemetry related rather than a motor fault.

The DX2 Ultra looks dead / nothing happens when I power it on

If the DX2 Ultra appears not to start, try this sequence:

Turn the DX2 Ultra off.
Unplug the power cable.
Unplug the USB cable.
Connect the USB cable to the PC.
Confirm the USB port is powered.
Connect the power cable.
Press the DX2 Ultra power button.
Wait for the self-check/self-level process.

If it still does not start after several attempts, contact us with:

A short video showing the startup attempt
Photos of the cables and power connection
Your Windows Device Manager / COM port screen
Any SimHub error messages

The DX2 Ultra beeps, locks to one side, or self-aligns incorrectly

Stop using the unit and contact support if the platform:

Beeps continuously
Locks to one side
Self-aligns at an unusual angle
Will not return to centre
Makes abnormal mechanical noises
Shows no torque or very weak motor response

Please send:

Order number
Photos of the installation
A video of the startup/self-check
A video of the issue happening
Any firmware version or SimHub error messages
Whether the problem started before or after a firmware update

Do not repeatedly force the platform by hand or continue testing if it appears locked or misaligned.

My seat/platform clunks or feels like something is loose

Stop testing and inspect the installation if you hear clunking, knocking or metallic movement.

Check:

Seat rail bolts
Profile-to-platform bolts
Platform-to-rig bolts
Universal joint area
Any brackets added during installation
Whether the unit was shifted during delivery or installation
Whether the seat is hitting the rig or accessories

If all visible fixings are tight and the noise remains, contact support with a video. Do not continue using the product aggressively if you suspect a loose joint or internal movement.
