1) disconnet the battery for 30mins+ 2) reconnect the battery and let the car idle for 5-10mins (make sure all the acessories are OFF) 3) turn the car off and disconnect the battery for ~30sec 4) 5) reconnect the battery, start the car and drive the rings off it. This speed's up the recalibration process, the 30mins is to clear the ECU so that it rememebers nothing, the 30sec is to let it reboot so to speak, its like updating system files on a PC it needs to reboot to use them the ECU works in the same way, and as for driving the "tit's" of your car, your ECU will learn how you drive and the first 2-300km is its steepest learning curve so you have to shape it so to speak so that you get the end result that you are looking for.
