Has anyone used the smart phone Torque App to log their Duramax? I have EFILive and it works great, but sometimes I just want to check something or verify a few PID's while driving down the road. If I get one of the OBD plug in modules and download the Torque app on my phone, can I just use it? My guess is that some of the specific PID's that we use to monitor / tune with might not be supported. Looking for others experiences and what works / doesn't work.
