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.
