Hey everyone. Not really sure where to post this so sorry if its in the wrong spot. But I just bought a nice obd 1&2 scanner. It also reads live data!. I understand what most of the live data things mean. Like fuel pressure. Short term fuel trim. Long term fuel trim 02 sensor bank one bank two etc.... but my question is how am I suppose to know what all of the numbers and percentages are suppose to be at for all the different live data scenarios. Are the suppose to be different for each kind of car or universal. I tried googleing it and couldn't come up with anything. Can someone please help? I would just like to figure out where all the numbers and percentages should be at so I can utalize the live data feature to the fullest! Hopefully someone can help.
