OBD-II live data parameters explained

What the app reads from the car in real time: 47 parameters with units and, where it does not depend on the make, normal values.

parameters in the reference47

with a plain-word explanation47

with normal values47

Normal values are given only where they do not depend on the make of the car. A made-up «normal range» is more dangerous than none: people replace healthy parts by it.
