    I know it’s just a meme, but an OBDII dongle — even a cheap $10 Bluetooth one — is super useful. You can read and reset the codes, and watch stats in real-time if so inclined.

      My car doesn’t have a reliable km/h gauge so I used an app to poll the speed of the car and show it up on my phone exactly in the way you described.

            A device talking to satellites in space is less exciting than some wire going to the engine 🤔

              Gps is a standard, anyone can do it. ODB2 is a mishmash of vendor spesific magic dust, and trap doors. It is impressive if you find a device that handles any car.

                The basic ODB2 stuff – which includes the speed readout – is a standard mandated by the government. It’s stuff like being able to talk to other modules over CANBUS that’s manufacturer-specific.

      The Bluetooth ones are definitely not as good as the dedicated ones but 100% better than nothing.

      It’s vital to know your own shit.

          They typically offer more features and info for even only a few dollars difference…

          …and my Bluetooth one died after a couple months just plugged in… Never had a standalone one do that.

      For older Hondas you can nab a Honda Interface Module for like $100. Installing the nutty pirated software is another fight entirely.
