Default Cobb Stage 1, is it worth it?

Like the title says, is it worth it.

Anyone have any issues with is causing problems?

I want some more engine power, but dont really want to replace any parts.

Will I feel and notice the difference?

Thanks

oh yeah me = noob on EM

You will feel more responsiveness. I wouldnt say you will feel more power. It's a pretty mild mod, but just makes driveability that much better. Less stumble, quicker spool, smooth powerband.

Why Is it worth more pennies in an 04/05 than in an 02/03?
Just wondering as I am considering getting an AP for my 02 as a first mod.

Because the 04/05's have more EM 'problems' to start with than the 02 .

Its still very much worth it on the 02, don't worry.

Personally I think it's a pretty good mod.. if you get bored with it you can buy a Turbo Back exhaust and download the Stage 2 map off their website and off you go...

Plus if your selling the car you can return the car to it's stock tune, unmarry the unit from your ECU, and sell it...

Just to note there have been some people reporting stalling issues at low RPMs with the AP on 04/05 WRXs.. I know Cobb was working on getting some datalogs from people / fixing whatever the problem was.. (search for more details)

HP-wise you'll get more of a gain with a turboback and stage 2. i think AP just gives better throttle response and smoother power load throughout more than just a few horsies to play with.

so how exactly does it work? Do I just plug something into the diagnostic port? Or do I have to pull out the ECU (whereever that is) and plug it into that?

Sorry, I am a complete noob when it comes to this stuff.

When you get your AP you are required to load the first base map

Included is a white connector. You will plug this in to the white connector under the dash, you will need to plug the 2-green connectors in (which are also under your dash). You then choose the base map you want to flash and bam your done. It takes about 20-min to flash your first map.

From there on out you can switch maps using the realtime maps

You will noticed the car drives a heck of alot more smooth. Turbo spools quicker you do add some HP but Stg 1 is not a huge jump by any means. Drivablity is the most seen improvement

It was well worth it to me. If you want to you can read the installation instructions on Cobbtuning.com .

Stage 2 is where it's at though. And you WILL go to stage 2, so be prepared to spend the $ on a turboback exhaust some time in the near future.

its worthwhile for a few reasons:
1. more power, flash a new stock map first, then the stage 1 map...people typically are comparing a "fully learned" stock to a fresh stage 1. Power is noticable for sure if you do this.

2. if you get a new cat free or high flow down pipe you can flash to stage 2 for free...this is where it is at

3. you get sick of it or want to go to custom tunes or feel it isn't worth it...unmarry it and you get most of your $$ back for resale. one of the best $$ resales of anything i know of.

In short if you are new to this stuff and want to try it out there isn't a better option.

MY AP should be here on Friday, do your reccommend that i flash the stock map 1st before the base map, or were you just using that as an example saying that if you were to flash the stock map, drive around, then flash a stage 1 you would notice more difference then just flashing stage 1 onto the alreday learned ecu?

I belive what he ment is there is a noticable difference from the Stock ECU map compared to the Stage 1 map

When you get the AP just flash the Stg1 91/93 as your base map

correct that is what i meant, flasht the stage 1 map as base...I just thought you could try a real time stock to see the difference. I wasn't sure that he was aware that the ECU learns and that he just reset it to base levels...

i currently have a turboback on mine. so when i get my AP i should re-flesh the stock ECU to be set at stage2 for base? or should i set it to that 'fuel economy mode' or whatever as a base? i use the car as a daily driver, so i'd prefer to have it save as much fuel as possible, and then on track day i can set it to stage2 and get some major power. is that right?

always flash your base map as what your car is.

flash to stage 2 if you have a tbe.

you can try doing the real time fuel econ mode if you want. My car is totally a daily driver and I have the stage 2 base map on all the time and never use fuel econ at all and get 21-24 mpg in mixed driving, haven't had a freeway trip to see hwy yet.

I actually get better milage with stage 2 then i did with a totally stock car

*edit* I'm sure you'd figure this out but there is only base maps for things like stock, stage 1 91/93, stage 2 91/93.....each of these also has a real time map version that contains less parameters than the full base map. So you flash the base map to what your car is and what fuel type (base contains appropriate cel blocks, boost control, etc), then use the real time for things like valet, anti-theft, fuel econ, etc.

ah i see i see, thanks for the help. and thanks for not screaming out 'do your research!' at me

better fuel mileage? well i find that hard to believe....but we'll find out when i pop it in. i get anywhere between 280-300 miles a tank...that's like what..17-19 miles a gallon? sheesh how'd you get such good mileage, you must drive on the highway ALL the time.

well i'm new to the EM thing, so i'm hoping to learn more about it with the Cobb AP. afterwards when i resurrect my car to be a pure race car, i get the ECUTEK and fine tune my ECU.

I did stage 1 before the accesport was made....a better deal if you are going to stay stage 1 than the accesport. If you are going to stay around the stage1 level, you can try grounding wires and the 3/8 tube (I think) mod and up (and maybe dp) for the price of ap and get similar results (no I don't have physical proof and so it is an 'opinion' ) your labor=free
I was going to stay stage 1 but now I have somehow ended up with stage 2 and some extra parts so if you are a mid level modder than ap is a GREAT deal. I think the real nutcase wrx'ers want more finetuning.

Stage 1 seemed to make better use of the axle-back exhaust - never seemed to make a difference, but Stage 1 seems much better than stock now. I don't think the stock ECU ever learned around that axle back but the Cobb tune with the axle back is giving me more than I expected.
Stage two very soon.

nope not all highway but not a lot of real stop and go either, I drive about 70 usually and not real light footed. Gained about 2 mpg going stage 2, and driving the same (you will probably loose a little right off the bat cause you will drive it harder) stay out of boosting it all the time and you get WAY better mileage. 80mph=bad mileage 70mph=ok mileage 60 mph= good milage. At 80mph you are constantly boosting a little, way worse than the vac you pull at lower speeds.

I usually get about 310-325 miles before the light is on in mixed driving, I think the stage 2 is more efficient due to no cats or high flow cat....

sweet..i can't wait to buy it i'm definitely interested in engine management. i'm a firm believer that you don't need major engine mods to increase horsepower, to me engine management means the ability to better control the engine you have now, something much more valuable than a mod with a simple hp increase.

yeah 80mph sucks. i really wish i had a 6th gear so that i can stay with VERY little boost. but meh..that won't be happening until my stock tranny blows and i get the RA gear set. oh, and is it worth investing money into a turbo gauge? or ANY sort of gauge for that matter? that empty space underneath my head unit looks kinda lonely...i was hoping i could put something there that's useful, any ideas?
