OBD Tally is a customisable OBD-II dashboard, data logger, and vehicle diagnostics companion created by a Ford Everest V6 owner for personal use—and shared in the hope that other drivers and enthusiasts find it useful too.

The app was built for and tested with the Veepeak OBDCheck BLE+ scanner. It may also work with other ELM327-compatible Bluetooth Low Energy OBD-II adapters, but compatibility cannot be guaranteed across every vehicle, adapter, or ECU.

Connect to your vehicle to view live sensor data, build personalised dashboards, monitor important values, investigate diagnostic trouble codes, and record driving sessions for later review.

Make the dashboard your own

OBD Tally gives you extensive control over how each PID is presented. You can:

• Create multiple dashboard pages for different driving or diagnostic situations.
• Choose from gauges, graphs, bars, numeric readouts, temperature displays, and status indicators.
• Configure display names, units, ranges, colours, warning levels, and critical thresholds.
• Add low-value alerts for parameters such as fuel level or pressure.
• Apply value smoothing to reduce noisy readings.
• Replace numerical values with custom labels—for example, displaying transmission positions instead of raw ECU values.
• Choose compact or expanded tile layouts.

Standard, custom, and vehicle-specific PIDs

The app includes standard OBD-II parameters and supports custom and imported manufacturer-specific PIDs.

A default profile for the Ford Everest V6 3.0L is included as a starting point. Because manufacturer-specific data can vary by model, year, engine, ECU calibration, and market, users should review and validate imported PID definitions against their own vehicle.

For other vehicles, OBD Tally includes an AI prompt generator that prepares a detailed prompt for creating a vehicle-specific CSV template. Copy the prompt into your preferred AI assistant, review the generated definitions, and import the resulting CSV file into the app. Profiles and individual PIDs can then be edited to suit your vehicle.

Record and review your drives

Record selected vehicle data during a trip and return to it later with:

• Interactive charts and sparklines.
• Route and location information when location recording is enabled.
