[ale] need 5" android tablet / phone for obd car instrumentation

[Neal Rhodes]

>From a safety standpoint I'd stick with the Scanguage.   It's the
simplest to place, easiest to read, and you can put it such that you can
see it without taking eyes far off the road. 

I do have torque and an odb reader and never use it. 

Scanguage IIs also can calibrate to your fuel injection system and keep
track of your fuel consumption, such that they can predict exactly how
many miles you have left before empty.   (basically by counting number
and length of each fuel injection pulse)    In the truck, which shows
empty when there are 6 gallons left, this is helpful for planning gas
stops accurately.    Especially when you have to find USLD instead of
gasoline. 

I don't recall other Android ODB software doing that in a way that I'd
trust. 

I really think the 4 button Scanguage is the way to go.   Dorking around
with the UI on an Android device while driving is just too distracting.
