went out to do some errands this afternoon (first time i've used the car since... sunday??)
so, i incorporated the comparison test between engine on VS engine off coasting into my drive.
i'll post the details later. but the figures are so good, i wanted to get them up here for your enjoyment. the fact is, i'm having a hard time believing they're accurate.
first, i can report that the kill switch works as hoped in practice: it kills the engine; doesn't put the scangauge to sleep; all the instruments (speedo/odo) continue working; and the engine can be key-/or bump-started with no difficulty afterwards.
i will have to get used to the switch though; i left it "off" by mistake a couple of times, causing me to miss one bump-start opportunity and forcing a key-start. krousdb - i can see the utility of an "interrupt" switch as you had set up. but i'll learn to use this properly since it can also serve as a simple security device.
(btw - bump start is inappropriate terminology for the technique; there's no "bump" when done correctly. we need to come up with a better term.)
anyway, the figures:
10 km loop; 100% city driving (stops every 3-5 blocks); several small hills; 3 longer hills; approx 17.5 to 18 minutes to complete each loop
light drizzle; damp/wet roads
60.3 mpg (US) - "engine OFF while coasting" loop 53.4 mpg (US) - "engine idling while coasting" loop
car was warmed up prior to test.
also, the warm weather has blown in from PA, apparently:
