Re: Security ???
I do this too with the Android Torque app and a Bluetooth OBDII link. My (2012) car does give fuel info, including fuel flow rate and tank level. And coolant temp and oil temp and throttle position and short- and long-term fuel trim, spark advance, mass air flow, voltage, RPM, location, blah, blah. I have it set to log data points to my home server via HTTP every five seconds. The phone sits comfortably wedged in the space that typically tells me what radio station I'm tuned to, so I don't need the HUD feature and it doesn't obscure anything important.
It can clear MIL trouble codes, and I suppose it could write other stuff too. There is an aftermarket in performance enhancing firmware. I'm not worried. I keep my eyes on the road and my hands upon the wheel... mostly.
