went out to do some errands
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: Conditions at SUPN6 as of (2:00 pm EST) 1900 GMT on 03/10/2006: Wind Direction (WDIR): SW ( 220 deg true ) Wind Speed (WSPD): 22 kts Wind Gust (GST): 25 kts Atmospheric Pressure (PRES): 29.44 in Air Temperature (ATMP): 45.7 °F |

re: bump start... how about "stealth start"? |

yeah running start could
yeah running start could work too. except it's not really running when i start it... and when it is, it makes that terrible sound ;)
i just did another short city trip. both legs were cold starts (drove about 4 km, parked for 40 minutes, drove back again.) used the on/off switch a bunch of times, and managed 51.5 mpg round trip. on a cold motor. in city driving. that rocks! why did i wait so long to try this? (if it's for real.... will have to wait a couple of weeks to see what this tank says at fill-up time) currently the switch is duct taped to my shifter, dangling wires everywhere. flick of the thumb does the job. very ergonomic. ugly as hell too. i may have to fix that up. i'll write up a proper description of the day's events and post a new experiment thread. |
