Enthusiasts gravitate to the OBDLink MX+, which reads advanced Ford MS-CAN and GM SW-CAN networks, streams live data at near 100 samples per second, and works with iOS, Android, Windows and third-party ELM327 apps. The Drive praised its responsiveness and accuracy. Bluetooth 3.0 is dated and this is the priciest option here, but for live data and broad app flexibility it leads.
- — Reads advanced Ford MS-CAN and GM SW-CAN networks most consumer tools cannot
- — Extremely fast live data, near 100 samples per second for real-time gauges and logging
- — Works with the free OBDLink app plus ELM327-compatible third-party apps like Car Scanner
- — Dated Bluetooth 3.0 (Classic) rather than modern BLE
- — Around $140, the most expensive option in this group
- — Advanced manufacturer features can require paid add-on apps
