Whats your best ecomod?

My best aeromod has been the belly pan I need to step it up and do more aero....

I went from 195/50 R15 to 195/60 R15 for just over 5% MPG gain. I'd go to 195/65 R15 next time, but they may not fit under the strut coils.

If your are havin to buy tires (tyres!) this is the best 'free' mpg increase. just over 5% is the secret.

Installing the vacuum gauge really opened up my eyes to just how sensitve the throttle is and how minute the differences are (physically) in my foot/muscles that make a huge difference in terms of mpg. I rode that way for about two weeks, just to get the feel of my muscles in my foot and start some initial training. At that point, I still had a ton of questions.

All of my questions were answered quickly when I installed MPGuino at the onset of week 3. That changed everything for me. I was then able to see, precisely, which gear to be in, when to coast, when NOT to coast, etc... You've GOT to get instrumentation. Your blind without it.

The MPGuino is now the more useful device for me of the two, but I'm glad I did the vac gauge only route for a week or two. It was useful for training and muscle memory.

Nowadays, I'm just about on "auto pilot". I drive eco, by nature. It's nice!

Good luck!!

I don't think hilly terrain is an issue, I live in the Blue Mountains and still saw improvement.
I think the question is,what percentage of your commute is spent in top gear.

1) ScanGauge
2) Kill Switch

or wait....
maybe

1) Kill Switch
2) ScanGauge

These are the two must-do mods. Together they are a mandatory first step.

98% of the journey is open road in high gear. lots of climbing to work! even more freewheeling back home id say almost 60% the way home will be freewheeling. kill switch would be perfect but I will loose my power steering and brakes completely (found that out the hard way). unfortunately in this country the traffic laws are more like guidelines. It will be dangerous to drive without proper steering and brakes because you always need to be on the lookout for the idiots, truck and taxis out there! also winter on unlucky days 80% of the journey is covered in mist

I would say my best gain is in my right foot. And the big amount of kilometers i drive. I have 60 liters + a week so i have a good and fast response on my changes. My scangauge did help some. But just to fine tune it. Also the tire preassure is an easy thing. Afther that i did a 50% grillblock and recently a downsloped small spoiler and some minor gapseals. Yesterday i did a 1:18.5 at 3c° outside. My record tank of 1:20.4 was at 30c°. And that was with only the tires and same driving style. Will have to see what it does in higher temps

so far I havnt touched my car. still waiting for new work contract to be sorted out. but until then I probably do the best ecomod of all. and that is share a car on a weekly basis to work and back with my brother as he works down the road!

I could reduce average Fuel Consumption approximately 30% by fitting a secondary intake tract before the filter. As mentioned in Autospeed.com
It reduces spiky vacuum occurrences during movement of the throttle butterfly valve, as the total intake diameter is approx 20% larger than that of the Throttle Body. I drive mostly urban which means lot of movements of the throttle. I used the flexible washing machine drain hose that costs approx USD 4.00 . I have changed that now to some plastic drain pipe and air conditioning insulation for a total of USD 3.00 and gets a smoother flow compare to the ribs on the hose.
