I'm using the Torque app on my Samsung Galaxy to monitor critical engine parameters as I get to know this 'new to me' vehicle. Something's not quite right.

The NOx readings though are not plausible. I'm getting in the neighborhood of -90s ppm for pre and post NOx. I don't understand negative parts per million. Also, DPF pressure is showing up to 900 PSI. I would expect this measurement to be in the inH20 range. I'm very annoyed that engine oil temperature is not available.

Has anyone noticed this before? I'm up to date on the Torque app btw.

Coolant temp is ok, in degF as is EGT's. EGR percentages look about right.

I'd like another way of viewing these parameters in real time, but I don't want to replace my CIC with an android version. Any other options besides using an old cell phone sticky-ed to my dash reading the ELM OBDII bluetooth device?
