Question about the ECU on a brand new car...?

When you buy a brand new car, you have to take it easy for about 5,000 km's or so, no redlining and just easy driving, correct? But my question is, does the ECU have to adjust for a certain period of time much like it does when you reset it? If so, what is this period of time/mileage? I'm just wondering, because when I get the new Civic, I'm going to want to install a SRI, which requires you to reset the ECU.

Ok, so basically until it goes in for it's first scheduled oil change (8,000 km's). Then after that I would be ok to install a SRI and reset the ECU.

I have an 02 LX with an AEM SRI....I barely have 4600 miles on the car....and about the ECU...you will feel a little difference right after you drive it but it will take 1-2 weeks to fully adjust....you will feel the full difference after that

Do you mean it will feel different after resetting the ECU?

That's another thing I meant to ask, I know to reset it you just unplug the negative lead on the battery, wait 10 minutes. But the next part is what confuses me. Do you connect the battery back up, wait 10 minutes before starting the car, and then let the car idle for another 10 minutes without touching the gas, or do you just hook the batter back up and start the car right away, let it idle for 10 minutes and don't touch the gas?

Oh yeah and after resetting the ECU do you have to baby it again, or can you floor it and do whatever?

yo all u need to do is disconnect the bat. for 10 minutes... reconnect it ... and go drive the car... it takes about 30 minutes for the ecu 2 adjust... i dont know where this 1-2 week BS is comin from but ITS NOT TRUE.... its 20-30 minutes and its fine. U dont even need to reset it. but when u install the SRI ... u need to disconnect the battery so u dont get zapd

Positive? Are you sure? All the threads I've read say negative, and don't touch the gas once you restart it for 10 minutes.

Basically what I would like to know now is do you have to baby the engine after you reset the ECU much like you baby it when you first buy the car and are breaking it in?

it really shouldn't make a difference if you disconnect the positive or the negative, it'll do the same thing.

On a side note, contrary to what most people think, the electric charge actually comes from the negative.

When I bought my car they told me that you no longer have to "baby" new cars. They just said not to drive the same speed or same RPM's for any extended period of time for the first 500 miles and after that you can drive how you please.

make sure you reset it right though. I followed the directions here for my SRI and I got 300 miles or so to the tank. I reset it again for another reason, but this time, I left it disconnected longer, and let it idle longer and now I get around 370+ miles to the tank.

Ok, so if I disconnected the battery before I started installing the SRI, that would be like 30 minutes right there. Then if I let it idle for like another 30 minutes after starting it back up I should be good to go right?
