With all respect, this confuses me and makes my head hurt. Wouldn't the chart show 1/∞mpg at all rpms? If it has a clutch and "N" it's a 1950 Dodge with Fluid Drive, right?

This refers to different cars, using the clutch when driving a manual, shifting to "N" when driving an automatic.

I'm normally using the injector pulse width display on the SuperMID. but it also works with the gph display on the Scangauge. As an example, if the SuperMID shows 2.3 usec pulse width when reving the unloaded engine at 2K rpm while sitting motionless in my driveway, then when I am driving at 2k rpm in any gear and the pulse width drops below 2.3 usec, I assume the engine is dragging rather than propelling.
