i hear so much about the Cobb Accessport. however, what, if any, are the major downsides to it? everyone raves about it, but does anyone know the long term effects of using it, say after 50K miles? 100k miles? how about gas mileage? any downsides that haven't really been brought up in the product's review?

i ask this cuz, if this is truly, no nonsense simple as they say upgrade, why didn't subaru have that setup for stock? whats the trade-off????

i'm not asking for in the case of a car with major/heavy mods, but just a stock/near stock setup with minimal work with a Stage I accessport setup...

 

I had it on my 02 for 40000 miles. Never had an issue, and it actually helped me get rid of some cel's I had. Really a great product. Gas mileage depends on your driving. mine stayed the same. But once you upgrade you will push the car a lot more, so you might get poorer mileage in beginning, but nothin drastic.

 

a few guys have had knocks and one guy blew his motor because he didnt know what that was

 

i'm guessing that dude blew his motor because he was using protunner?

 

no just the regualr access port

 

If he was running the cobb base maps in ca., that probably happened because their maps tend to run the cars lean. To run ap in ca., you need to have it tuned here. See the gruppe-s thread for more info.

 

sounds more like an isolated case, no? i haven't heard of anyone having that problem. do you know after how long it happened?

 

Downsides....cost..?

Not really any downsides to more power, smoother curve, mulitiple ecu maps and cel scanner.

 

correct it was the CA map

blew up less than a month

but you have to know what a knock and ping are

 

still a n00b...how do you identify knock and ping? I'm not too worried though since my protune maps were done pretty constervatively

 

so its not really a good idea to get AP in ca unless u get it protuned eh?... that kinda stucks

 

not as long as you use the CA specific maps. they are made for our crappy gas

 

Uh ru-x, you got the right idea. A protune will give you more power AND safety. Listen to the self-proclaimed noob and you won't get the full story. There is another factor that plays a role in combustion. Hint: we have more of it here than they have over there, which is why their maps make our cars run lean. And if you're paranoid, buy a knock sensor and you'll be less likely to blow your motor under any circumstance.

 

ping sounds like a ping like hitting a golf driver i guess kinda not really sorry

knock soudns like a fast rattle. its easy to get confused with the turbo sound but it sounds like a BB is in a cylinder

 

man this stuff u guys talking about scares me..dont want to blow my motor, ihave an 06 wrx. i just installed stage 1 a week ago, its nice.. i feel the difference. im from cali, the maps im using is ca-stage 1. hopefully i wont any problem, any suggestion pls let me know, thats a big help
