(My) Connected Car Project: some more data from OBD2

It is not easy, if you don't work every day with cars, to understand what is the meaning of all the data coming from OBD2.

What I have found, and I'm able to read, is MAF, that is the quantity of air consumed, per second.
The gasoline is proportional and therefore MAF is an indirect measure of gasoline consumed.

I have also added to my prototype several other data.

This is the JSON message at this point:
