Using DFCO to increase your MPG

[BailOut]

@eTiMaGo:

Thanks for the information! My ScanGauge II hasn't arrived yet (I got in with the group buy on PriusChat so it should be here shortly) so I'm glad someone else is providing hard data.


@Nutzoids:

It sounds like you're making progress, and that's great. :) No, using the friction brakes will not disengage DFCO. The 3 ways you will leave DFCO are:

1) Touching the gas pedal.
2) I don't know the exact RPM yet but if you drop below about 6 MPH in any gear the ECU will start sending fuel.
3) Using the clutch on the MT or using overdrive on the AT.

For example, using just the brakes (no clutch) while engine braking will not affect DFCO at all, and this is how I dump extra speed on short, steeper sections of the downhill parts of my mountain commute.
