Ok someone must know how to correctly reset a 2000 Si ECU?
and when too? like after a mod?

Two ways: First you can pull the fuse for the ECU and leave it out for 20 minutes then put it back in. Second you can disconnect the battery cable for the same time, and reconnect it.

20mins...huh...more like 2minutes...one way you can check if its reset is turn your radio on and see if your presets are fuked up

If you have a stock radio make sure you have the code to re-set the radio otherwise, good luck trying to get the dealer to give it to you......

Don't you also turn the car on and leave it at idol for a minute or two? Then you turn it off and then turn on again and drive. Are these steps unessessary?

All I did once was to remove the battery cable for a few minutes...put it back, start the engine and done deal.....I had to reprogram the radio.....which was a breeze......

Cool, thanks.

I've heard a lot of people say that with ODB II you don't even have to reset the ECU, it will pick it up automatically. But, I would still. Just to be sure.

from what ive heard it does pick up automatically but it takes time. After driving for a while the new settings will gradually replace the old ones.

obd2 has a "learn" feature which means the stock settings will slowlycome back, thats why you wanna reset it every few months..

Hmm are you sure it ain't the other way around, 'I heard', that it learns the new settings and should stay that way. What you just wrote just doesn't seem right to me, but what do I know ?
