Raising the bar

[zpiloto]

The top ten list gets higher and higher, both in total and over EPA.

Matt do you have any historical data form a year ago? It's winter and the numbers are quite impressive and are still going up. Any predictions for August?

It would be interesting to see what the differences are compared to a 1-year archive.

zpiloto : I see you are in the top ten!. I do have to say, 'Por Gratis' is going to
be beaten by 'Bluey' soon - my MPG is getting better and better!. I do think my limit is going to be about 40MPG (which is number 30 on the list) - I would have to find another 20% economy before I could get on the top 10

Well your gas log is trending the right direction. I see that your latest mod has killed your FE. Time to get rid of the cup holder You can make up the 20% by technique. Good luck. Every day is a chance to make one more little change and in 6 months you have a 4 MPG increase .

landspeed, in your garage you have your car weight as 2860. 2860 WHAT. If it is pounds you are carrying 200-300# more than anyone else with a car like yours. Just take out the the extra weight and pick up instant MPG.

I can pull some stuff out soon. I'm pretty certain I retained the gaslog data from the old software, but my brain isn't working at 100% (not enough sleep) so I can't remember.

now that we're over a year old, it should be fun to compare year to year.

Actually, the mod has increased fuel economy when doing slow (average
40mph) commuting, but decreased highway fuel economy. This is because
I have got a wideband lambda gauge, which shows the ratio hit 14.7 when
I am under moderate load - and I don't want my engine to detonate and
destroy itself. My *average* fuel economy has actually improved (although
it has got very cold out).

My plan is to adjust the fuel to lean-burn for commuting (it actually ends
up stoichometric anyway - reduces the impact of warm-up enrichment),
and put it back to normal when going on the motorway - which will
let me use higher throttle positions to get better overall fuel economy!.

Sorry, but when I looked at your gaslog I thought the last entry said cup holder So what exactly is a place holder? is that covered in another thread? Don't want to get to far off topic.

[landspeed]

Oh OK

The last entry is just there so that all the mileage values go on the log (or the
last one is drawn off the image, to the right). I would get better MPG uphill with normal burn though, and I plan to adjust it back to normal this weekend - and see if I can keep my MPGs for short journeys up.

Back to topic!.

I also agree that having the option of noting significant mods on the gaslog is a
good idea - anyone else agree?
