Effords begin to show....
The past 220 miles I've payed much more attention to driving teknique, and it's begginning to show, combined with my mods.

Today I filled up, and for the first time I hit the official combined EPA with an avarage on the last 5,7 gal of fuel - 40 mpg.

Yupiii

I'm improving.

Conditions are still not good, with winter wheater, snow, down to -5 deg C etc.
Also many small trips and som ideling when scraping ice etc.

One happy ecomodder....

Well - at set of reacing caps would be 150 - 200 USD shipped to europe, so I took an another rute.

The car came fittet wit plastic hupcaps on the steeel rims, and they pretty much had a good shape, but to many holes along the rim.

So I went to the builders store, and god some 0,6 mm aluminium sheets, layed out the plastic hub caps, marked up, and cut out 4 round discs.

Made a cutout out for the air valve. Pop-riveted he aluminium to the plastic hub caps, and gave the whole lot a good silver spray paint to finish it up.

Volia! - 4 nice racing moon hub caps.

Picture will follow to morrow. Cost - alu sheets and some rivets and paint - both in my workshop.

Hi Jyden, Nice work on the car so far. I do have to ask being as your in europe and have different speed regulations then we do here.
What is hyour average speed on your commute? I am just looking at your milage and wondering what kind of traffic you go through?

[Jyden]

Hi boarder4life. We have speedlimits in Town's at 30 miles, country roads at 50- 55 miles, and on highways it's 70 and some places 80 miles.

I have many small trips around town, postoffice, groserystore, library etc. with lots of traffic lights, and then some days with longer commutes.

I think, that the problem for now is the winter. Sub zero temperatures, many coldstarts etc., combines with a 10 yo old car that are in for a tune up. Also the wintertires, are doing no good for milage. Too much resistance I think.

Also the 1,0 L enginge in the Yaris (Vitz) has i't main tourque at 3800 RPM's, so you have to be very carefull, not to press to hard on the speeder, which will do nothing at all, except decrease milage.

Everything has to happen on the first ½ inch of the speeder, if one wants god milage

Hi,

I'm intrigued by the effect of the cold air mod on FE. I haven't done this mod myself but with Engine On Coasting I've noticed my engine takes much longer to get up to temps - my plan is to block the grill when I finally get time to do some work on the car. I note you have done that.

If the engine is cold though, won't that make the ECU pump in more fuel when you don't need it, so in the long run it may harm FE rather than improve it ?

Thoughts ?

[Jyden]

@ Arrgonis - I'm not shure yet. My last tank of fuel yielded dissapointing results, so I have now removed the heat reflecting material from the intake to se if that helps / improve things.

ECU / enginemanagement systems are complicated things. If you change one parameter i.e. intake temp - the ECU will change 5 or more other things, as the ECU will try to find the optimum burn mix of air / fuel to reduce emmisions and optimise the catalyst converter to its optimum temp.

Normally cold air will give the engine more oxygen, thus increase engine effenciensy, as you can induce more fuel pr. air unit, thus adding to the enegines performance and lowering tourque a bit.

Engine might take longer to warm up - not good for FE, and depending on the engine type and ECU it might also have an influence at the burn.

I think, that one should try and see what happends.

As you run a diesel engine, I belive it would improve your FE, but I cant say for shure.

Diesels normaly are made without the restiction of a throttle valve, thus having a greater airflow all the time.
