Air pressure Not needed (only when flying)
Air temperature Not really needed, air cooler takes care of that
Air/Fuel ratio OK WB better
Ammeter Depends on battery's state of discharge
Amp temperature Does not exist, current causes wires to get hot but there is no amp tem gauge.
Boost pressure Same as below
Boost/Vacuum OK
Differential temperature Not needed
Exhaust gas temperature Wide band O2 and gauge is far better, like having a heart monitor connected to your engine
Fuel level You have that, low means bad
Fuel pressure OK
Knock Great for FI, not all DME software versions supports it
Nitrous pressure OK
Oil pressure OK
Oil temperature OK
Temperature Same as Air Temp, not needed, only when flying.
Tire pressure/Internal tire temperature Pressure OK, the latter not needed, exernal OK
Transfer case temperature Not needed
Transmission temperature Not needed
Vacuum Same as Boost/Vacuum
Voltmeter OK
Water temperature OK
All limits depends on car and apps.
