I found what looks like a killer app for the 'droid devices, Torque-BHP (http://torque-bhp.com/)
I've been playing with it on my Nexus 7 with a Bluetooth ODB2/ELM transmitter and have it working well with the RS 6, but the one thing that I REALLY wanted and have yet to get working is a boost gauge. There are 3 methods of boost calc:
Prefer MAP (default)
Prefer MAF
Prefer ALT
I've tried all three... no reading.
The app has the capability of adding a custom "PID", basically asking info like:
ODB2 Mode and PID (in hex - eg: '01 0D' for speed)
Min Val
Max Val
Scale Factor
Unit Type
Equation
Anyone using this and if so figured out how to get a working (and reasonably accurate) boost gauge?
Sorry for the low qual pic.. but gives you an idea what it looks like. This was before calibration and getting my car profile set up accurately in regards to weight, fuel, etc. The HP/Torque gauges are pretty slick.
TIA!
