Lada Diag – Comprehensive ECU Diagnostics for VAZ Vehicles via OBD2
Lada Diag is a dedicated diagnostic tool designed for VAZ (Lada) vehicles, offering powerful OBD2-based engine diagnostics using a standard OBD2 interface. Compatible with a wide range of VAZ models including the Kalina, Priora, 2110, 2114, Niva, and classic 2107, Lada Diag provides reliable access to critical ECU data and fault information.
Key Features:
- Read and Clear DTCs: Instantly retrieve stored engine fault codes and clear them after repairs.
- Real-Time ECU Data Monitoring: View live sensor readings and engine parameters (e.g., RPM, coolant temperature, oxygen sensor values, fuel trim, and more).
- Sensor & System Diagnostics: Analyze individual sensor performance and assess cylinder operation consistency to detect misfires or anomalies.
- Automatic Parameter Interpretation: All data is automatically translated into user-friendly formats for easy interpretation.
- Wide ECU Compatibility: Fully tested and functional with major ECU systems, including:
- January 5.1
- BOSCH MP7.0
- BOSCH M7.9.7
- ECU M75
- BOSCH ME17.9.7
How It Works:
- Connect the OBD2 adapter (supports standard ELM327 and compatible clones) to your vehicle’s diagnostic port.
- Establish communication via the vehicle’s onboard data bus (CAN or ISO 9141-2).
- Lada Diag automatically detects your ECU type and begins streaming real-time data.
Supported Devices:
- ELM327-based adapters (original and clones)
- Bluetooth and USB OBD2 dongles
- All standard OBD2-compliant hardware
Important Notes:
- Data availability varies based on your vehicle’s ECU model and firmware version.
- The free version includes advertisements. A premium upgrade removes ads and unlocks additional features (e.g., advanced data logging, historical trend analysis, and export options).
✅ Fully tested and verified across multiple VAZ platforms and ECU variants.
✅ Stable connections and reliable data streaming confirmed on all supported models.
Whether you're a mechanic, DIY enthusiast, or daily driver, Lada Diag delivers accurate, real-time insights to help maintain engine health, troubleshoot issues quickly, and keep your VAZ running smoothly.
