Here's a screenshot from MegalogViewer of my car running a short trip on the highway.
(Right-click the image to show its larger/original size).

It's showing engine RPM (White trace) and MAP (=Engine load or 'reversed vacuum') as the Red trace in the top row.

The lower part shows Engine Coolant temp in Green and Intake air temp in Yellow.

The car had been driven before this day, but you can see the engine temp rising from the start, while the intake air temp rising very slowly until after the highway part (center section) and the car encounters slower stop&go traffic.
