Getting your Leo Bodnar SLI PRO working seamlessly with your Logitech G29, G920, or similar wheel and pedal sets within Logitech's LMU (Logitech Motoring Unit) software, specifically LM7, can sometimes present a challenge. This guide will walk you through the process, covering common issues and providing solutions. This applies to other LMUs beyond LM7 as well.

Understanding the Challenge: SLI PRO and LMUs

The Leo Bodnar SLI PRO is a highly versatile device, allowing precise control over various inputs and outputs. LMUs, however, often have their own proprietary drivers and configurations. The key is to configure both devices to work together harmoniously. The challenge arises because LMUs generally expect to communicate directly with the wheel and pedals and may not immediately recognize the SLI PRO's intermediary role.

Step-by-Step Guide: Getting the SLI PRO and LM7 to Play Nice

1. Hardware Setup:

• Connect the SLI PRO: Connect the SLI PRO to your PC via USB. Ensure it's powered correctly.
• Connect Wheel and Pedals to SLI PRO: Connect your wheel and pedals to the appropriate ports on the SLI PRO. Consult the SLI PRO's manual for the correct connections.
• Connect SLI PRO to LM7: You do not connect the wheel and pedals directly to the computer for use with the SLI PRO and LM7. The SLI PRO acts as the intermediary.

2. Software Configuration:

• Install SLI PRO Software: Install the Leo Bodnar SLI PRO software and configure it according to the manufacturer's instructions. This software is crucial for mapping inputs and outputs.
• Configure Input Mapping (SLI PRO): Within the SLI PRO software, carefully map each input from your wheel and pedals to the corresponding outputs. This is where you tell the SLI PRO what each pedal/wheel action should trigger. Accurate mapping is critical. You'll need to experiment to determine the correct axes and buttons. The software provides a clear interface for this.
• Start LM7: Launch LM7. LM7 should now recognize the SLI PRO as your input device rather than the wheel and pedals directly. The SLI PRO will act as a virtual wheel and pedals for LM7.

3. LM7 Configuration:

• Selecting the SLI PRO in LM7: In LM7's settings, you should select the SLI PRO (or its associated virtual port) as the input device for your wheel and pedals. This might be listed under "Wheel," "Pedals," or a similar section, depending on LM7's version. The exact name will depend on how the SLI PRO is presented to Windows after the mapping process. Look for entries that clearly indicate the SLI PRO or its virtual controller representation.
• Calibration (If Necessary): LM7 might require calibration after connecting the SLI PRO. Follow LM7's on-screen instructions.
• Testing: Thoroughly test all inputs in LM7, ensuring proper responsiveness and calibration. You may need to make adjustments in either the SLI PRO software or LM7.

Troubleshooting Common Issues:

• LM7 Doesn't Recognize SLI PRO: Verify the SLI PRO's USB connection and that its drivers are correctly installed. Check LM7's input device settings; the SLI PRO may show up as a different name than expected. Try restarting both the SLI PRO software and LM7.
• Incorrect Input Mapping: Carefully double-check your input mapping in the SLI PRO software. Even a slight misconfiguration can lead to unexpected behavior.
• Driver Conflicts: Uninstall and reinstall the SLI PRO drivers, ensuring no conflicts exist with other devices or drivers.

Advanced Configuration Options:

For advanced users, the SLI PRO software allows for customizing the ranges and sensitivity of your wheel and pedals, enabling fine-tuned control.

Conclusion: Enjoy Enhanced Control

By carefully following these steps and troubleshooting potential issues, you should successfully integrate your Leo Bodnar SLI PRO with your LM7, unlocking enhanced control and precision for your racing simulations. Remember to consult the documentation for both the SLI PRO and LM7 for specific instructions relevant to your setup and software versions. Using the SLI PRO often gives you much more precise control and options for calibration beyond what LM7 offers directly.
