Allowing ECU to reset after mod installation

Hey Focus Fanatii,

I had the chance to remove the terminals on my battery this weekend when I was wiring my interior neons.

I remember reading something that after installing an aftermarket exhaust/intake you should remove the terminals from the battery afterwards for 30 minutes so the ECU can reset itself.

It's bizaar, my exhaust has a lower pitch then when installed, I've noticed a slight change in throttle response as well.

Am I imagining this or should you allow the ECU to reset for 30 minutes after installing an exhaust or intake?

Paulie

either leave it off for 10 mins or take it off and stand on the brake pedal for 30 seconds. either will reset the ecu. If you have any serious mods, it may need to learn for a little while before getting back to normal, but it shouldnt take long.

You need to drive the vehicle so the ECU's adaptive learning can go thru its strategies.
