That lines up predictably with a broad range of other vehicles that members here and elsewhere have tested, as you did.

Generally passenger vehicles get the best cruising fuel economy at the lowest road speed after top gear is engaged. (Though sometimes at the lowest road speed in second from highest gear, for some vehicles with higher aerodynamic drag.)

FYI, see: http://ecomodder.com/forum/showthrea...you-15182.html

Glad you're having fun with the ScanGauge - I remember being pretty excited by the world of testing possibilities it opened up when I first got mine for my Pontiac Firefly (clone of your Suzuki, with the 1.0L 3-cylinder though).
