I thought that the ECU was self adjusting after xxx miles of driving.
Please explain.
I'm not sure how long it will take it to adjust.
I've observed long term fuel trim numbers seem to take more than a few hundred miles to adjust. I've reset my ECU by disconnecting the battery, then captured fuel trim info with my durametric after a few hundred miles. A few months later, when i check fuel trims again, they are different.

Just my experience.

On my 2000 S, I've had no ill effects from resetting the ECU. Any time I make a change to the exhaust or intake, I reset the ECU.
