OBD Scanner

Beta

Selected: No active vehicle

Not connected
Connect a USB OBD-II adapter to begin. Bluetooth requires a Web Bluetooth-capable browser.

Desktop USB Scanner

Connect an ELM327-compatible USB adapter using desktop Chrome or Edge. Plug it into the vehicle, turn the ignition on, then connect it here.

Bluetooth Scanner (BLE)

Beta

Pair a BLE ELM327-compatible OBD-II adapter directly from TorqueList on desktop or mobile. Plug the adapter into the vehicle and turn the ignition on first.

This browser does not expose Bluetooth device access.

Use desktop Chrome/Edge or a BLE-capable Android browser. Firefox and normal iPhone/iPad Safari do not provide the Web Bluetooth API.

Bluetooth MFi / iPhone Scanner

iOS App

For Apple MFi / External Accessory OBD-II scanners. These scanners require the native TorqueList iPhone/iPad app and cannot be connected directly from the normal web browser.

Native iOS connection required

TorqueList will use Apple External Accessory / supported native Bluetooth APIs for compatible MFi scanners. BLE scanners should use the Bluetooth Scanner option above.

Fuel Trim Diagnostics

Normal

STFT and LTFT are ECU corrections, not values a generic scanner directly sets. TorqueList combines them and helps diagnose why the ECU is adding or removing fuel.

Compare Operating Conditions

Capture trims at idle, around 2,500 RPM with no load, and steady cruise. TorqueList compares the pattern instead of guessing from one number.

Torque Fuel-Trim Analysis

Start Live Data to read fuel trims.

Fuel Calibration / Learned Trim Reset

TorqueList will only enable ECU writes or learned-trim resets for a verified vehicle/ECU profile and a supported programming interface. Generic ELM327 USB/BLE adapters stay read-only for calibration changes.

Transmission Monitoring

Waiting

Standard OBD-II transmission monitoring is available for every detected vehicle.

Every OBD-II vehicle gets transmission-code monitoring. ATF temperature, gear, converter, speed and pressure channels are added automatically from the best source-backed year/make/model/transmission profile when the TCM exposes them. 2 enhanced profiles loaded.
