First I think this is a great app worth ever cent. I do have a few questions though. FYI I am using a Archos70 Android(2.2) tablet with a KIWI Bluetooth OBD2.

1. Is there a help file or manual to read?
2. Does the HP and Torque calculations need a GPS? I can't seem to get them to work. I have entered the cars weight and displacement.
3. Can I turn off the GPS and Accelerometer data in the logging?

I made a mistake the first time I used Torque on my Volvo V70. I cleared the fault codes thinking they would be back soon. That was over two weeks ago and the check engine light still is not back on. There is not any historic faults or pending fault either. Here are the signals Torque is reading.

O2 Volts Bank 1 sensor 2(V)
Intake Air Temp(°C)
Engine Coolant Temp(°C)
Engine Load(%)
Mass Air Flow Rate(g/s)
Fuel trim bank 1 sensor 2(%)
Throttle Position
RPM
Speed

As you can see it only see's one O2 sensor and one Fuel Trim. I know there are two O2 sensors on this car not sure about the fuel trim. I would have thought there would be a turbo boost pressure also. I know one of the O2 is bad.
