## What is BimmerDash?

Transform your iPhone into a high-performance, gaming-inspired digital cockpit gauge cluster. BimmerDash is a premier OBD-II vehicle monitoring App designed specifically for Bimmer enthusiasts.

【 Engine & ECU Optimized for F-Chassis & B-Series / N-Series 】
BimmerDash is deeply optimized for B48, B58, S55, N20, and N55 engine control units (ECU), ensuring high-precision data logging and rapid PID polling response.

【 Apple Intelligence On-Device AI Diagnostics 】
• 15-Minute Telemetry Backtest: Fully automatic analysis of boost curves, ignition timing advance, and knock retard events powered by the iPhone's local Apple Neural Engine (ANE).
• 100% On-Device Privacy: Zero dependencies on external cloud servers. Operates at full speed on tracks or remote roads without cellular signal.

【 Apple CarPlay & Live Activities 】
• CarPlay Multi-Layout Support: Strictly complies with Apple driving safety guidelines with 10-second interval peak and average metric calculations.
• Live Activities: Real-time telemetry monitoring on Lock Screen and Dynamic Island.

【 18 Core Performance Metrics 】
Track both engine health and track-focused metrics simultaneously, including:
• Engine Speed (RPM) & Live Vehicle Speed
• Turbo Boost Pressure
• Engine Oil Temp & Coolant Temp
• Throttle Position
• Battery Voltage
...and many other critical data points to help you manage thermal efficiency and power delivery.

【 Hardware & Connection Requirements 】
• This app requires a compatible aftermarket Bluetooth 4.0 (BLE / Bluetooth Low Energy) OBD-II adapter (e.g., vLinker BM+, OBDLink CX, or any standard BLE-compliant ELM327 / OBD2 adapter).
• Classic Bluetooth 2.0 / 3.0 (legacy non-BLE) and Wi-Fi-only OBD adapters are NOT supported by iOS and will not connect.
• Quick Tip: Do NOT pair the device in your iPhone’s iOS Bluetooth settings. Simply turn on Bluetooth, plug in your adapter, and connect seamlessly directly inside the app.

【 Disclaimer & Safety Information 】
• Drive safely. Do NOT attempt to operate or configure this app while driving.
• Data displayed by this app is intended for performance monitoring and enthusiast reference only. It is not a substitute for professional factory diagnostic tools used for repair or mechanical troubleshooting.
• All vehicle platform codes, model names, and related terms are properties of their respective registered owners. This app is an independent third-party enthusiast monitoring tool.
