And the instant and average MPG is surprisingly accurate, IF you program the parameters correctly.
I like to watch the IAT reading as compared to the ambient reading on the instrument panel, as well as the engine temp. Mine usually runs around 186 deg, the temp dial is one needle width below half at that temp.
In the summer, idling with A/C on, I have seem 210 deg, the needle is 2 widths above half.
