Question What's the official method to reset ECU?

I've heard different things, so I wanted a real answer. Is this a good thing to do anytime you change the breathing characteristics of your car?

I just reset it for the hell of it. Its a simple thing, just take the NEGATIVE cable off the battery, let the car sit powerless for an hour or so, than put it back. Start the car (mine never stars after a reset), and let it idle. Don't touch gas or anything else. Than shut it, and turn it on again, and drive it around.

Or something close to whatever I said above. Its not a big deal.

trhe first time starting it after connecting the battery, make sure to let the engine get to normal running temp without touching the gas...then it's safe to shut off. After that, you can just go.

The OFFICIAL method, as in the only one recognized by SOA or a dealer, is to reset it with the Subaru Select Tool.

But yes, what our yellow friend mentioned is the correct "end-user" way.

There is a quicker method that will not take an hour. Disconect the battery then step on the brake pedal to discharge the electrical system, replace the battery cables and your are done. As mentioned above, start the vehicle without touching the gas.

Quick newbie questions: why and when should I reset the ECU? (I have searched the forums but haven't found anything that explains it in newbie terms.) I'm still in break-in, so I don't want to mess with anything. After 1k miles or so, what benefits will resetting the ECU give me?

Thanks for being patient with a newbie

An ECU reset is helpful (not required) after a performance mod is added to your car. It allows the ECU to learn more quickly, rather than over time. Also, after a re-set you want to drive your car "briskly".
