TRACK Connect · hardware

Start with your phone. Add hardware when it pays off.

Everything TRACK needs is already in your phone. Connect adds precision GPS for tighter timing, cameras for better onboards and OBD-II for engine data, and tells you plainly which devices are tested and which aren’t yet.

We list exactly what works today and what doesn’t. No universal OBD claims. If a device hasn’t been tested on real hardware yet, we say so.

OBD-II reports RPM, speed and temperatures at a few Hz per value. Its “throttle position” is the ECU’s throttle-plate reading, not your pedal, and TRACK labels it that way. Product names describe compatibility only and imply no partnership or endorsement.

25 Hz ≠ accurate.

Sample rate is how often you get a position. Accuracy is how close each one is. A fast receiver with poor accuracy is still off, just more often. TRACK reports both, and every lap carries its own timing uncertainty.

01How it works

How it works

  1. 01

    Phone only

    GPS around 1 Hz, motion sensors up to 100 Hz and the camera: enough to time and coach.

  2. 02

    Add precision

    A 25 Hz GPS receiver sharpens timing, delta and traces.

  3. 03

    Add engine data

    An OBD-II adapter adds RPM, temperatures and more, depending on your car.

  4. 04

    Add cameras

    A GoPro gives a sharper onboard that TRACK starts, stops and syncs.

02What’s in it

Built, tested, and labelled honestly.

Every feature shows where it really stands: built and tested, in beta, awaiting hardware validation, or planned.

  • OBD-II engine

    Start-up, channel discovery, parsing and conservative polling, with results shown per car.

    Built · device-dependent

  • RaceBox decoder

    Built from RaceBox’s published protocol, with clock alignment over Bluetooth.

    Awaiting hardware validation

  • GoPro control and import

    Pairing, clock set, opt-in record start/stop, status and post-session Wi-Fi import.

    Awaiting hardware validation

  • Sensors hub per car

    Recommended, available and live sensors for each car, with a live test screen.

    In the app beta

  • Pro CAN gateways

    Read-only, user-mapped channels from motorsport loggers.

Questions

Do I need any hardware?

No. The phone alone times laps and coaches. Hardware improves precision and adds data.

Will my cheap OBD adapter work?

On iPhone it must be Bluetooth LE. Classic-Bluetooth adapters can work with the planned Android app.

Does TRACK ever write to my car?

Never. It only reads data.
