Mounting to Wheel Base

The first step in setting up your GSI wheel is to mount it properly to your wheel base.

MOUNTING WARNINGS

GSI wheels are designed for broad compatibility with most hubs and quick releases on the market via the 70mm bolt pattern (PCD). For safe and proper installation, please follow these guidelines:

  • Prefer Using Non-Threaded Mounting Accessories
     Attach hubs or quick releases using non-threaded holes to avoid potential damage.

  • Use Captive Screws for Threaded Mounting Accessories
     If your hub or quick release requires mounting with its own threads, use Captive Screws to safely connect them. Never use regular screws for thread-to-thread connections, otherwise you will damage the mounting accessory and wheel.

  • Avoid Long Screws
    Before connecting a hub or quick release, ensure the screws won't extend more than 4mm into the wheel body once attached, as this may damage internal electronics.

  • Provide USB Cable Clearance
    Maintain at least 50mm of space between the wheel body and wheel base to prevent the coiled USB cable from making contact with the base.

PC Setup

Once mounted, connect the wheel to your PC and configure the software.

Connect to PC

  1. 1GSI Coiled USB Cable (PC-Side)
    Ensure your powered USB hub is connected to your PC and power source, then connect the cable to the powered USB hub.
  2. 2GSI Coiled USB Cable (Wheel-Side)
    Connect the cable to your wheel, ensuring the keyed portion lines up with the connector in the wheel (see Step 3).
  3. 3Keyed Connector
    The wheel-side of the cable has a small notch. Ensure this notch is oriented at the top so it easily connects to the wheel. Thread the metal coupling to the wheel until snug.

Dual Clutch Setup

Before you can use your clutches in a simulator, they will need to be calibrated.

  1. 1Open GSI Control Center and click on Calibration, then slowly pull and release both clutches. Your clutches are now calibrated.
  2. 2After calibration, click either the Dual Clutch (Most Common) or the Gas and Brake options.
  • Dual Clutch mode
    Set the bite point by adjusting the slider on the right or inputting the value manually, then click Set Bite Point.
  • Set Dz Values
    If a clutch is too sensitive and is reporting inputs without being pulled (Min) or does not report 100% when fully pulled (Max), increase the value by 1 and click Set Dz Values to save the setting. Repeat until you have eliminated any deadzones.

Note:
We recommend testing each clutch while in the Gas and Brake mode in order to test the range of each clutch. Do not use the Calibration mode as it always outputs the raw output from the sensors, rather than what is output to the sim.

Enjoy your GXL V1

Troubleshooting

For proper operation, you need to have a clean, reliable USB data throughput signal and the absence of EMI (Electro Magnetic Interference) from other devices. 

  • Connect wheel via a powered USB hub or directly to computer. 
  • Avoid excessively long USB extension cables. Data degrades on longer USB extensions.  
  • AMD systems with widely known poor USB performance update to AGESA bios 1.2.0.2 or higher. (check your motherboard manufacturer website)
  • Check for EMI (Electro Magnetic Interference) and ground rig if needed. 
  • Try alternate USB ports if one port is not performing to spec.
  • Check coiled cable to make sure cable housing is screwed on tight. 
  • USB shares data throughput with all devices on the system. Make sure you are not overloading the USB tree. 
  • Use a dedicated PCIE USB card. (We recommend NEC chipset cards)

  1. 1Detach the QRS-1 halves by squeezing the pull ring.
  2. 2 Use the provided shorter screws only to attach the wheel-side to your wheel. Using screws longer longer than 16mm may damage the wheel's internal electronics.
  3. 3With the wheel base shaft centered, place the QRS-1 base-side with the text upright on your wheel base mount and thread the appropriate length screw (we recommend using the SC2-X Adapter for Simucube 2 wheel bases).
  4. 4Place the QRS-1 wheel-side with the GSI logo facing up on the back of the wheel and align the screw holes, install the appropriate number of short screws only.
  5. 5Using the included Allen key, thread the screws down until they lay flush. Use the stubby end of the Allen key to tighten the screws.

SC2-X Mounting

  1. 1SC2-X Adapter
    Before starting, ensure your Simucube 2 wheel base is completely turned off and that all attachments are removed from the wheel base. The pre-installed Simucube base-side QR should be visible with the logo upright.
  2. 2M5 30mm Screws (Included)
    Using a 4mm HEX Allen key, remove the x3 pre-installed screws from the Simucube base-side QR. Align the SC2-X Adapter to the wheel base shaft screw holes and install with the provided screws.
  3. 3 QRS-1 Base Side (For Reference)
    Once the SC2-X is installed, you'll be able to install accessories to your Simucube like the QRS-1, or other 70mm/50.8mm PCD QRs, hubs, etc.
  4. 4Base-Side Screws
    DO NOT use screws that travel more than 5mm past the lip of accessories you are attaching to the SC2-X to avoid damaging the adapter, and to ensure they can be tightened securely.

Cleaning Instructions

General Cleaning

  1. Before cleaning, unplug the coiled USB cable from the wheel.
  2. Use a soft microfiber towel lightly dampened with 99% isopropyl alcohol to gently wipe the wheel.
  3. Use a soft detailing brush to remove debris from hard-to-reach areas.
  4. Be careful not to apply too much pressure on the labels as this may damage the matte finish.

Label Cleaning

  1. Use a cotton swab dipped in 99% isopropyl alcohol to clean the labels.
  2. Gently brush the surface of the labels with the dampened cotton swab and use the dry side to absorb any excess alcohol.
  3. This helps to prevent drying spots from forming on the labels.

Label Maintenance

  1. To clean label surfaces, use a cotton swab or lint-free cloth lightly dampened in 99% isopropyl alcohol and apply very light pressure with small circular motions.
  2. To remove minor label surface blemishes, use a heat gun set to 38°C/~100°F from a distance of 3cm/~1in while evenly distributing heat to the affected area.
  3. Avoid applying too much heat to the wheel face, as this may damage the labels/buttons.

Label Replacement

  1. To replace the labels, remove all front knobs from the wheel. Loosen (but don't remove) the set screw until the knob can be lifted up from the wheel face.
  2. Carefully peel the labels with your fingernails or a soft plastic prying tool to avoid damaging the wheel faceplate.
  3. If any adhesive residue is left behind, use the adhesive side of the removed labels to repeatedly stick and unstick the surface to lift the leftover adhesive residue.
  4. If the adhesive is difficult to remove, we recommend dampening a cotton swab in either acetone or Goof-Off and using a circular motion to apply the chemical to the remaining adhesive. Always proceed with caution when handling volatile chemicals and follow their respective safety guidelines.

Shifter Maintenance

GSI Shifters come pre-lubricated from the factory. With extended use, you will need to re-apply a small amount of PTFE lubricant in the specified locations (see image) to keep them working at their best. DO NOT use spray lubricants, and DO NOT use excess lubricant. Be cautious during application and do not get it onto other parts of the wheel.

  1. 1Lubricant Area #1
  2. 2Lubricant Area #2

Clutch Maintenance & Adjustments

  1. 1 Maintenance
    GSI Clutches may need to have PTFE lubricant applied to the spring resting points inside the clutch housing in order to keep the actuation smooth.
  2. 2Adjustments
    Using a 2mm HEX Allen key with a stubby end, loosen (but do not remove) both screws on both ends of the clutch to until you can freely move the retention paddle. Set the retention paddle to a position that feels comfortable to you and then retighten both screws.
