Is there any problem in doing so, and can I leave the hood of the car up while Cobb is updating? Any problem with opening/closing the hood during update, or does it have to be left alone like the car door?

I only do this only when installing the COBB. I place the charger on first, leave hood open. Then follow instruction as noted. Stay in the car and don't open the door. Hood open is fine.

When you are in the car, it would be difficult to close in the hood without opening the car door.
