So I didn't see a thread on this so I thought I would share. I felt like experimenting so I ordered a bluetooth obdII adapter from Amazon for $25 and got Torque Pro from the Android store for $5. So far I have to say I like it, it gives a lot of valuable statistics on the xfire that can easily replace having to get a custom made gauge pod. I'll submit a better screen shot at a later date, I'm still trying to figure out what I can actually get from the ECU. There's easily 100 options to choose from. Also you can use this as a code reader in case your engine light comes on. I hope some people can get some use out of this.

*edit*
Torque Pro and retrieve these on a 05 limited 6spd
Fuel System Status
Engine Load
Coolant Temp
short/long fuel trim for banks 1+2
intake pressure
RPM
Intake Temp
Speed GPS/ECU
Timing Advance
MAF flow rate
throttle position
secondary air status
o2 sensor voltage

and a few others that are pretty much trip meters.

Hope this helps!
