Car passed inspection. Bluetooth OBD II thing is totally worth it.

EDIT Gotta say my phone never felt more like a tricorder, when I had it scanning all the data from the various sensors and the computer embedded in my car.

For the record this app worked well for me. In terms of hardware, I just searched for “OBD” and “ELM327” and got the cheapest one I could find, and it worked.

I will mention the security around the cheapest ones doesn’t seem to be great. Mine is continuously and eternally in pairing mode willing to pair with any device with a pin of “1234.” So I won’t be leaving mine plugged in when im not using it. YMMV with slightly less dirt cheap models.
