Android Torque app and ELM327 Bluetooth

Almost all commonly available ELM327 bluetooth adapters use a Chinese clone of the ELM327 chip. The initial offering of the ELM327 from Elm was not protected; it’s firmware could be easily downloaded, so knockoffs quickly came about. They are much cheaper in quantity than the real ELM327. Finding an adapter with a real Elm Electronics chip is quite difficult, although I haven’t had trouble with the clone. Sometimes it will be reluctant to connect at first, but I suspect this has more to do with bluetooth than anything else.

Beyond OBDII – Small, Dedicated, Aftermarket Onboard Computers

Imagine pulling into your garage, and when your new onboard aftermarket computer is triggered by proximity to a WiFi node in your garage, the data from your drive [note upon re-read: not computer hard drive, but rather your “outing” in your Volvo] is sent to your home Mac or PC, and all parameters for the drive are processed into a neat report that may let you know before a code is set that your thermostat is likely getting a little long in the tooth. The report is emailed to your email account, and arrives at your phone (and your 14-year-old’s phone, because s/he is next in line to your Volvo and wants to ensure you’re treating it right) before you turn it off.

Volvo Drive Cycle For Readiness

I noticed today when someone posted about their readiness codes that this is not in the repair database, so I’m adding it. Basically, if you go for emissions testing and they scan your computer and find that your car is not ready although there are no diagnostic trouble codes (DTC’s) or check engine light, you’ll fail the inspection. A regular OBD-II scanner will also tell you that your readiness codes are not set. Volvo gives us a specific Drive Cycle that has to be done at least twice to set these codes so that you will pass inspection. In this thread, you’ll find those instructions.
