Check the fitment and location between the 2, they're almost identical. As for function, i have no clue if it will destroy the MAF or not

anyone know some details about how the ECU learns your driving habits and how that plays out in terms of performance and mileage?

for instance, if my driving behavior is different during the break in 1000 miles vs normal driving, how will that affect performance/mileage?

is the program such that it's an entirely cumulative learning experience for the entire life of the car, the past X miles, or ???

btw, Navi folks -- does the navi HU show album artwork?
I Dont have an i pod, but i think if you read from the usb and also have album art it might show it. We dont really have much of the album art on the flash drive.

All learned parameters in the ecu are stored in their own tables and could potentially change at any time. If you change your habits it will learn under the new conditions, however it might take a while to adjust/overwrite the all existing learned responses (i.e. change the values of all cells in the table). You can clear all the learned parameters with an ecu reset (clears all cells). This will make the learned values table a clean slate which should make getting to optimal values happen faster if it is experiencing new conditions.

So in conclusion, there really isnt any "permenance" to what was learned and the ecu will be constantly adjusting. A reset will give you a clean slate.

i know i brake a lot more in this car then i used to driving a manual transmission in my previous car, so that also contributes to what i see. added on that is the fact that my old car had wheel covers which likely allowed less brake dust to get through to the front side of the wheel.
Ya I have a manual so I downshift when braking from speeds of 35+..sometimes when going less, but then I tend to be more lazy and just coast/brake.

Because race car.

If you want to stop just "fine" ya oem. I plan on doing ebc rotors and one of their street/race pads, and replacing the brake fluid with some motul or something similar and braided lines.

Default CVT downshifting

so, i can finally say i observed it in my feb 2012 build car. but i have to say, i think it behaves as it should, if i can read into the minds of the engineers. when cruising on the highway at 60mph and i encounted a sharp downgrade, if i let my foot fully off the gas and the hill was steep enough to cause a fairly rapid acceleration to 70+ mph, the car downshifted to do some engine breaking. i knew these hills today were going to be short lived and i was trying to optimize mileage without anyone in front of me to worry about tailgating, so paddle shifted to "6th" and i got a nice downhill coast.

i'm sure others have experienced it in lesser circumstances, but i think this is a pretty good design for the average driver of automatics, who in IMHO and experience, often ride their brakes way too much down steep declines.

I do downshift and slowly pump the brakes to prevent overheating the rotors, but it still seems to produce a lot of brake dust... Unless if I shift down to 'gear' 1 and rev the crap out of my engine I will still be gaining speed relatively fast due to the steep grade.

I would rather brake and have to change cheap and easy brake pads faster then downshift and have to change the harder And more expensive clutch faster. It's all preference though.

Why the hell would you do that in a econobox? I really hope you're just screwing with me.

In my experience, the colder the brake pads, the more dust they produce. Once they get to operating temp they stop better and dust less.

There seems to be quite the mix on here which really keeps things interesting. A large portion of owners bought for ecomony and several of them aren't quite happy with the numbers yet. A few other owners bought for what seems to be the name and look and several of them post a lot about performance, short shiifters, springs, airboxes, and now brakes. Hopefully everyone gets what they want out of their Imprezas but I get the feeling that those of you that want to turn an econobox into a pocket racer aren't going to get much more than sound, harsh ride, and noisy/touchy brakes.

Keep it interesting guys and remember what you bought and what it is/isn't capable of!

Sorry, almost forgot the stereo guys - enjoy your tunes and hope they don't cause any rattles (not like your rattles nubsub)!

I want to get a hood deflector, I can get it for half the cost the dealer wants for it installed. Anyone know how it is mounted?
I am the biggest of retards and I managed to install my hood deflector just fine. Note that if you do go the self install route that you should ignore the step "mark holes on hood" until after mounting the two brackets that have the screw in attachment points on the hood. Why? Because those two spots are fixed and mandatory, the other spots you create to line up with those fixed spots. Attempting to eyeball the alignment and mark the holes as the instructions say is a stupid waste (as I found out).

I'll try and remember to get a picture tomorrow of what I mean.

The race car was just some good old cliche fun.

And seriously why not stop better. Ya the motul and braided lines might be a little far out there but it's not that expensive to do so why not. There's only so much you can do to tinker with these things, and I like to have some kinda project to do.

Then you can drop some STI differentials in the thing and figure out how to get direct injection from the BRZ to work, and turbo, or just screw Subaru and drop an LS1 in it, because, race car!

Or you could figure out you bought an economy car, and not a sports car, and not waste your money trying to get it to be a race car, when it is never going to be that, no matter how big a wing you put on the back.

The 2.0i does not need an intake installed, if you want better airflow the airbox that's there is more than capable of handling the needs of the engine, install a Perrin panel foam air filter or a K&N.

Next, hood scoop, because, race car.

People like to modify their vehicles to make them their own...and for something to do. I don't see anything wrong with someone doing that. I have a friend that has an 10-11 second "econobox" cavalier. Looks stock, no wing, little larger tires for traction. Different strokes for different folks.

If someone wants to add to the performance or handling of a "non sports version" of a car, why the fuss? I came for 500+hp cars and wanted something that got good gas mileage and handled decent. I personally wouldn't mind a little better performance out of any vehicle i own...even if it is an "econo box". No need to hate.

I find it interesting that alot of people criticising the short shift mod happen to be CVT owners. Its a functional mod that allows you to acclerate quicker. I find that my foot work is often waiting for my shifting and in stop and go traffic im sure others will appreciate my ability to get moving quicker as a result of the quick shift. It has real world application. Now, fart can Exhaust, metal pedals or big wings seem to be a little on the wanna be faster side of things.

I am used to german transmissions which seem to be more crisp.. i really hoping that the short shift mod will get me closer to what im used to.

i own a manual transmission in a different car. i have seen the need for the short shifter as well as a long shifter. the short shifter are great for that direct feel. im not sure how the manual feels in the imp, i own the cvt. but sometimes i like the long shifter for road racing and autox conditions. it allows me to quickly and easily shift and quickly put my hands back onto the steering wheel. i shift pretty fast with both short and long shifters, so it is never about the ability to shift faster. the short shifter in my other car makes it harder to shift because the distance to the fulcrum is shorten and vice versa the long shifter is much easier to shift.

RoyB,
There are huge differences between "Sleepers" and "Posers".


auskip,
Seriously on CVT's?!?
