Can you tune n/a engines with the stock ecu?

If your asking if one could tune a stock ecu, the yes. You can tune them via opensource or with a Cobb Accessport

PM williaty. He did my tune and I am very happy with it. I decided to go with him over phat botti because I personally trust him more and he has more experience tuning NA than phat botti IMO.

In all honesty, its not very difficult to tune an N/A subaru. You would not benefit more one way or another.

I've tuned over 50 N/A's, I wouldnt call that inexperienced


I have also tuned a few 08+ cars with cams. Head work really works wonders with these cars if tuned for.

Just out of sheer curiosity, does anybody know what a tune on an otherwise stock vehicle would net? I'm finding it really hard to find bolt-on parts for my 2010 and was wondering if just doing a tune would be beneficial and/or cost effective.

Yes but have you been a member of the N/A forum since 2004? I didn't think so. I just trust Ty more than you. No offense.

Yes, Opensource tune would be the way to go... I dont think you seriously need a tune on a NA unless you have some major work done like cams, full exhaust including header, intake system or N/A-T meaning turbo on your NA motor. I mean i could totally be wrong but i thought i remember someone saying its pointless to waste the money on a NA Tune.

I've been thinking about this, because my buddy said that he had a friend that tuned an 07 2.5i and to him it was like night and day. Not sure what exactly that means, but I have an 05 RS with full exhaust, about to get new intake in the spring, and I'm wondering what exactly would a tune do for me car?

It makes it feel like it wants to live, rather than the "kill me now" feeling they have stock. It just makes it a lot more fun to drive.

If one wanted to tune their n/a though, lets say a 08+. Would a Cobb AP be a way to go? Ive looked around for n/a 08+ support and it looks like they've discontinued it.

Agreed! Because my car is drive by wire, and auto, the throttle response now is much improved, and that makes a difference no matter what kind of driving you are doing. It also feels smoother now, all the way to redline, whereas before it felt like it was done long before redline.

You won't net huge increases like the turbo guys, but you will get more area under the curve, which is harder to sell the way people have been trained to judge these things, but it makes a big difference in the real world.

Does this apply to stock set-ups, as well? I would agree with the "kill me now" description. It really feels like the engine is pissed at you for asking it to work. Coming from a Civic this is the biggest drag about the Subaru (and about the only complaint) The Honda may have been weaker, but it was always willing.

Yes, even with a stock setup, it'll totally change how the car feels. The issue is the tuning to meet all the EPA bull****, not the engine itself.

That's good to know. Is the EPA BS you are referring to for the emissions or for the fuel mileage test? I have to run through the emissions lane every couple of years and can't have a CEL on (I don't want a CEL on, anyway). Does a typical tune adversely affect MPG? Do I have to go back to the stock tune before taking it in for warranty work ( if there is any)? Am I asking too many questions?

Both emissions and economy. Most stock-hardware tunes don't make much of any difference to economy. People will claim otherwise, but no one who is doing the testing properly has ever seen it. I would be shocked if you didn't pass a sniffer emissions test even with a tuned car. You can pass a sniffer with no cats and a good tune. The limits for what you can have on your own car are way less strict than what they have to be for an OEM.

No sniffers around here. Straight OBDII link. Monitors run and passed and you're good to go.

If it's just an OBD-II scan, that's easy since the DTCs can be disabled and Readiness can be forced.

What would I need for a MY '03 with stock motor, aftermarket catback and 3" intake tube mod from fender to torque box?

Is it worth it in terms of performance for a n/a bugeye?

Thanks!
