🛠️ Tips for Best Results

• Ensure your vehicle is ignition ON (without starting the engine) for stable connection.
• Use a trusted ELM327 Bluetooth adapter (e.g., V2.0, V3.0, or higher with full OBDII support).
• Avoid using cheap, unbranded ELM327 clones – they often fail to communicate with GM’s proprietary CAN protocols.
• For best results, pair your ELM327 device via Bluetooth to your Android device and ensure the app has proper permissions.

• This app is not affiliated with Opel, Vauxhall, Chevrolet, or General Motors.
