ESP32 ALDL Dashboard connects your Android phone to classic GM OBD1 vehicles (such as the 1986 Pontiac Fiero 1227170 ECM) via a custom ESP32 Bluetooth SPP bridge, decoding the 160-baud ALDL datastream in real time.

Features:
- Animated radial RPM gauge and live readouts for speed, coolant temp, MAP, TPS, O2 sensor, MAT, and battery voltage
- Status flags for closed-loop mode, rich/lean mixture, TCC lockup, and A/C clutch
- BLM and Integrator fuel-trim heatmap grid across 14 RPM and 17 MAP bands with dynamic colour coding
- Multi-parameter line charts in single or 2x2 grid mode for 12 selectable metrics
- Trouble code decoder with human-readable descriptions
- Dual logging: Room database sessions and TunerPro RT-compatible CSV export to Downloads/ALDLLogs
- Optional raw binary stream recording for advanced playback and diagnostics
- In-app log browser for viewing, opening, or sharing CSV and BIN files
- Persistent settings for temperature units, alert thresholds, and auto-logging preferences

Requirements: Android 7.0 or higher; an ESP32 device programmed to bridge the ALDL serial pin to Classic Bluetooth SPP (named ESP32-ALDL).
