What causes you to have to use the brakes, is not pushing the throttle too far down, but not having the sense to let off in time.

It may come as a surprise to you, but I already knew that.

So why did you make a post that indicated that you didn't?

Ok, moving on now,

I am already noticing a change in driving technique is making a difference, I am at 29 miles and the needle is still above the full mark. I even used the pulse and glide method today. I even glided into the parking lot and into a parking space where I can just pull straight out! Pretty fun saving gas, a lot more to think about while driving to keep me busy. Maybe I will make a video of my drive so everyone can give me some good pointers, jakobnev, STAY AWAY! lol Kidding

Waiting for the MPGuido to come in, does anybody know how long they take after donations?

Before proceeding I think we need a pic of your E90. I do like that bodystyle!

It is fun to try to plan your fuel consumption and coast around... almost as fun as hitting apexes haha. It's too bad it's not a manual- I don't think engine off coasting would go too well with an auto.

Here is a shot from a few months ago, E90? I guess there other names for this chassis but I call it a AE92, going by chassis code. That's my 90 GTU RX7 in the background I sold already but I have 2 others. and I been having ideas of a high mpg rotary vehicle which is going to be fun, they get pretty decent mileage but if you compare it to it's 1.3 displacement 22mph is not great.
Yes this car handles pretty light since it weighs nothing almost.


As you can see, I like white cars and black.
Yea, It isn't as bad but Manual would be easier.
I shift into Neutral first then shut off the engine with key.
Fall about 10mpg then engine on and back into D and pulsed up.
Worked like a charm. I just saw one on craigslist you guys have to check it out:
1990 Toyota Corolla SR5 coupe with goofy paint - OBO
What a beauty she is huh! lol
I offered the guy $500 so I could use the transmission and engine for a swap later but he wouldn't budge from 700.

What Sven7 meant is engine off coasting with an automatic transmission is usually not a good practice. The pump in the transmission is not turning with the engine off so bushings,bearings,hydraulics are not getting the line pressure that they are designed for while output shaft and whatever is coupled to it is turning while you are coasting. So tranny is not happy. With an auto trans it's better to leave the engine on (idle) while neutral coasting.Still getting very good MPG as long as the coasting speed is reasonable. (say not slower than 25 MPH just as a guide)

Thanks for telling me before I kill my trans but that would have been a good excuse to get a manual! lol

Yeah, E90 is the code for the generation, including sedans, wagons etc. I know my Corollas up to the AE86 and then... well, FWD happened. lol

That CL ad is amazing. Any car with Audrey Hepburn on the hood is OK by me! I just emailed a fine arts friend, asking for some paintings on the Anal Probe.

Yeah I didn't know for sure, but figured it couldn't be good for the tranny.

Oh, and your photo didn't work for some reason?

Humm weird, I can see my own picture?

You can also click on the link of my garage.
IDK I would not be caught dead in that red corolla but I would strip it for transmission/motor for a full rebuild and eco mods?I been thinking could I possibly add a fuel control module like a piggyback safc and mess around with the injector bandwidths for idle and driving and get better mpg?
Still waiting on my MPGuino or MPGuido how long do they take to send shipping confirmation?

Man you are getting 39+mpg put of a ford probe! That's pretty cool!
I am still on my first tank of gas since I joined the forum and I only travel 15-25 miles a day so it might be a week or two more for my MPG estimates. I hope to get the MPGuido soon so I can calibrate it and get better figures and see my driving habits and places to improve. I guess getting a vacuum meter is next on the list. Hey I think my 1989 BMW 525i had one of these right? the stock ones ran off vacuum also if I'm not mistaken.

And yes, today I did not shut my car off and tend to do more coasting from 70 and coast about a 1/4 mile *est and need to use the brakes very little or not at all. during my 20 mile'ish trip i make about 4-6 times. Today there was traffic but I was able to coast till I only used the brakes for the stop sign. Some Mercedes behind me got impatient and started tailgating me i just ignored him since I was going faster then the speed limit of 30. I was doing 38mph and coasting before my pulse of acceleration.

Here are a few pics of the ole' beater i just snapped with my phone cam, I already see what I will do with those mud guards. Remove and fabricate them for wind deflection in front of the tires! They are rubber and flexible, no wonder they didn't fall off already from bottoming out.*I need struts*. Before all that I need to fab an under body after I burn through about 3-4 tanks of gas I will starts the mods once I can get a base MPG figure and have the MPGuido!

I am sure just by removing all 4 of them I can get an extra 2 MPG or so on the freeway! From the looks of it if I remove them and switch sides in rear, put them in front of the tires they can deflect some air from hitting the tires. The body tapers inwards at the bottom and leaving more of the tire/wheel hanging out to catch air in the back I will have to try it out but the front looks alright, so I may just have to do this for the rear and remove the fronts then get some MPG figures later.

Under body is not to bad but can use some paneling in the future.


Now looking for shocks and lowering springs.
