Give it about 30 minutes to be sure.

The ECU learns to adapt a best fit mode of running according to the condition of the engine and the climate around it. For instance, if you replace or unblock a dirty air filter the ECU will eventually learn the change and operate the engine accordingly.
Resetting the ECU does NOT remove warning lights and/or fault codes from the system. If you have symptoms of a fault, such as back firing and judder it would suggest you really do have a fault.
The ECU reset takes about 30 mins to be safe and the car will re-learn what it needs in about 100 miles of normal driving. Expect lower mpg during that period too.
