The problem is likely the tailoring of A to D conversion for PIDs that are probably not standard across manufacturers. Hence your pre-programmed PID channels being incorrect. The Analogues from sensors range from DC thru AC and onto pulse/PWM which require specific processing prior to scaling/digitisation. That needs full access to the front end software. I don't know enough about it and am guessing really...in that the PIDs are proxies for raw data directly (almost) off the various sensors.

hey aussiebob - great post very interesting! how did you get Torque to show the DPF soot mass, regen time etc can you share the setup for all the readings on that screen please it would be really useful? thanks!

I found this link with some codes for the Nissan Xtrail and put them into Torque Pro and they seem to have worked, are these the codes you used and did you find any other useful ones? No idea if the numbers are correct but they seem sensible, it did a regen when soot level got up to around 30g. DPF operating mode changed from 1 to 3 and the exhaust temp went from 200ish to 600ish as it did the regen, soot gradually dropped down to 1g over 5-10mins then other numbers went back to what they were before once it had finished the regen so similar to what you reported above. codes were here https://baustralianxtrail.runboard.com/t134736
