I'm having a hard time finding information on what are proper/normal levels for the many different sensors
in cars. I assume some categories depend on the kind of car/make/model/tuned etc., but I think most of them apply the same all across the board.

Can you guys help me fill out the list of what "proper/healthy/optimal" levels should be for these categories? (please correct me if I am wrong
but these are based on what I either researched or have monitored on my own car).

Coolant: 90 degrees
Trans. Temp: 90 degrees
Catalytic Converter: 500 - 800 degrees
Barometric pressure: 14.6 - 14.7 give or take
Throttle at idle: 12
RPMs at idle: 700-1000 rpm
Fuel rail pressure: 700-800 (idle), 1000-1500 (driving)
Fuel pressure: ?
Load: ?
Vacuum: -20-23 (idle)
Battery voltage: 14.0-14.6
Ignition timing: ?

Yes, those are definitely the right values for your car and engine type.
