So I recently just discovered this awesome app for the android that connects to your car via the ODB port.

Here's a link where you can get some info:

You also need a bluetooth ODB adapter, I got mine from amazon for 23$.

It reads all the sensory information in real time from your car and can also do diagnostics.

You can also have it track your commute times to see how fast you were going through the roads.

Here's a map/speed graph of a recent trip i took.


Here's some of the sensor information you can get in real time, I'm not currently connected to the adapter so its not showing anything.


It's pretty neat and I can't wait to use it on a track.

 

I have pretty much the same setup. Great app.

I'm pretty sure I wouldn't use it to post evidence of speed limit infractions online though
