OBDLink MX Bluetooth

What is it? It plugs into your vehicles diagnostic port (OBD/OBDII on all cars 2000 and higher) and streams the data from your cars computers via Bluetooth to an app on a laptop or phone. 

What can you do with it? You can reset check engine lights, see all error codes, fuel consumption, speed, rpm, hp, turbo boost.... a whole host of things.

Connecting it was easy enough -

• Install the software on your laptop (from download or included CD) or phone (From play store - link provided in the box)
•  locate the OBD port on your car and plug it in.  Turn on the ignition (don't need to start the car)
• Pair with your phone/laptop (Press the tiny button on the OBDLink, then scan for devices from your phone/laptop.) If you used Bluetooth anything, you know the drill.
• Start the app. Prosper.

The application starts reading the data immediately.

The a

OBD Free App

For Android users they also recommend Torque ( a paid app by a third party - about $5.00USD as of this writing).   It seems to have more bells and whistles than the included app, with custom layouts, plug-ins by other developers etc.   For a couple bucks, sure why not.  Don't bother with the free version of Torque - by all accounts its buggy and not as feature-rich.

If you want to know what's going on with your car, I highly recommend this product.  And you might even save the money you spend on it the next time your check engine light comes on.  There are cheaper Bluetooth (and usb) OBD devices, but I've read they are slower, have a high failure rate, and sometimes are not recognized by applications like Torque.  For a few extra bucks, I figure save the headache and frustration.
