Paully,
It's not the length of time that it's disconnected that counts. Just being disconnected for a moment will clear most of what the computer has learned about your car. When you start it up again, then the computer starts re-learning the proper settings, and if you have added some mods, the computer will learn about them also. It might stumble a bit at first when you restart the car as it's learning the new settings, but just drive it like you will everyday and hopefully if you were having problems, they will disappear, but if your just doing it to re-learn new mods, they will be re-programmed in the learning process.
