Is there a noise or anything on the display that shows that the reset was done correctly?
Do this
1. Turn the igniiton key to the "on" position which is just before you crank the engine to start.
2. Press the accelerator to the floor and hold for 5 seconds.
3. Then turn the key to the off position but do not remove the key, then release the accelerator.
4. Wait at least 5 minutes, the ECU is then reset.
The ECU rest procedure only erases the adaptive transmission and throttle settings. It does not erase any of the fuel, timing or other programming.

No, you will definitely feel the difference because it's in learning mode. If you drive it slow, it will learn that....if you drive it fast and hard it will learn that. what I usually do after a reset is to make sure you have some time do drive it hard. Don't worry though, you can do this process over and over.

So you have to then after leave the key in the ignition for 5 mins or you can then lock and walk away from the car?
