Yes:

Nice. Seems a little complicated tho but I'm sure I will learn it

Just to clarify, I wasn't saying to stay away from OS tuning in general, like Cobb. I was referring to the tools that allow you to monkey with tuning parameters yourself, as doing so without knowing what you're doing could easily cause damage to your engine. Still, I found the article informative. Can't say I won't change my mind, but for now, I'm going to stick with a stock powertrain until the warranty is out. Good luck, whichever route you go! Personally, I love the stock power, but I'm coming to an STi from the Legacy. Every time I drive my Legacy, I'm reminded why I bought the STi.

There are OS base maps just like there are Cobb base maps. OS and ATR both allow you to modify maps, so an overzealous laptop monkey can just as easily blow their motor by tinkering when they shouldn't be. The big difference (shy of SD tuning, which isn't applicable on mild setups, and wouldn't likely be implemented by one of said laptop monkeys) is whether you want a proprietary device or a laptop as a flash medium.

So I'm tryna understand this tuning thing. So I'll have a million questions to keep my car safe.

Use a good quality oil and get a good quality tune. That should be it.

Just wondering. Is the ots Cobb tunes classified as a good quality tune?

It's a base map; one-size-fits-all solution to EM. Some cars take the map well, some don't. You won't know until you flash it on your car and datalog. As a general rule, Cobb puts out an alright map.

Ok so I my car don't like it then what? Get a tune for my car?

Also I've been seeing that most of the Cobb OTS maps are for 91 octane. We use 93 here in MD how would this effect the tune?

Cobb has maps for 91 and 93 octane.

Contact Cobb and have them fix the problem. You're paying for their support of their product, as well as the IP behind the device/maps. If that doesn't work, look to a third-party for help remedying the situation.

It would provide a bit of a detonation buffer, as the map will be detuned a bit to run on the lower octane. You wouldn't be the first person to do that as a safety net.

Ok i see, now with a detuned tune I wouldn't be getting the full "effect" of it would I?

Ohhhh I didn't know this. I'm just getting my questions out the way before I get so I kno what I expect. Make sense?

The car is held back a bit due to the decreased knock resistance 91 offers vs 93. Running 93, you're still detuned a bit, but you have the knock buffer at hand.

Picture you are playing baseball with your nephews at a family gathering. They're all around 12 years old. Are you going to be throwing 80MPH heaters at them, or will you dial it back a bit to something they could actually hit?

[SubiEj255]

Ahhhh I see what you mean. You my friend are extremely helpful. So it wouldn't be a bad idea to be on a safe side then.

Once the ecu is reflashed the warranty is practically gone correct? If i were to return it to stock, SOA can see that can't they

Old thread I know, but will a step or two colder plugs help prevent ring land?
