Question Need help to read BMW ECU data

I need some help regarding OBD readings from my ECU.
These are not trouble codes but OBD data on the engin performance for tuners.

I would like to know what are these measures, what is their unit and what is the reference for the values.
The readings are coming from the ECU of a BMW 330ci 2002.


If there is a web site with specific description on BMW ECU data ?
Please don't post staff on trouble codes ...
