Ecumaster Serial Bluetooth Module The Ecumaster Serial Bluetooth Module is the essential wireless accessory for owners of the EMU Classic and the original "Silver Box" EMU. While modern units often move towards CAN-based communication, this module utilizes the dedicated RS232 serial expansion port to provide a high-stability, one-way data stream to your Android or iOS device. It effectively turns your smartphone or tablet into a high-resolution, multi-page digital dashboard, eliminating the need for expensive physical gauges and messy cabin wiring. By transmitting over 30 critical engine parameters in real-time, the Serial Bluetooth Module allows for instant monitoring of engine health and performance. It is fully compatible with the official Ecumaster Dash app and the highly acclaimed RealDash software, providing a professional-grade virtual cockpit experience with customisable alarms and visual themes. Technical Authority & Key Features Legacy Compatibility: Specifically designed for the 5-pin expansion port found on the EMU Classic and original EMU units. Real-Time Data Streaming: Transmits vital channels including RPM, MAP, TPS, IAT, AFR, and Oil Pressure with minimal latency for accurate driver feedback. One-Way Communication: Optimized for data logging and display, ensuring the module does not interfere with the ECU’s primary processing tasks. Diagnostic Monitoring: Facilitates the viewing and clearing of Check Engine Codes (CEL) directly from your mobile device via the Android application. Visual Status Feedback: Features an integrated Red LED indicator: Blinking: Searching for a Bluetooth connection. Solid: Securely paired and transmitting data. Customisable Desktops: When used with the Ecumaster Dash app, users can configure up to 6 unique desktops with various gauge styles (analog, digital, or graph).
