Break In Affect
My question is I know that you should drive the car soft the first 1200 miles, but from reading in the forums I discovered that the car adapts to your driving habits. Will breaking in the car the proper way, make the car more of a sleeper?  Thanks | | Reply » Break In Affect |

Thanks | Here is something I remember from the radio show"Car Talk". I am sure you can find a lotof info on the web.
The piston rings are "seating" to the cylinder walls during the break-in period. It's crucial that there is a perfect, tight fit between the outside of the pistons and the inside of the cylinder walls. The pistons are surrounded by spring-loaded rings, which push out against the walls and keep the seal tight. If you do not allow it to "seat", oil will get past the rings and you'll "burn oil." If the rings and the cylinder walls don't come out of the factory matching up perfectly, the break-in period gives them a chance to conform to each other (which involves going slowly and varying the speed).
Apparently 1,200 miles on is not an exact science. Each manufacturer makes its best guess as to how much time the rings will need based on warranty claims.
Apparently Porche is so confident in their precision manufacturing that they require no break-in period at all. Porsche says you can get in a new Porsche and drive it out of the showroom however you want.

Thanks | There are two questions embedded in there. "What is the mechanical breakin period?" and "how does the adaptive software work?"
Hawk123 answered your first question. My understanding of the second question is that it continuously adapts, so if you drive it for 5000 miles it will adapt to you, but if you sell the car to someone else, it will then adapt to them.
If you want, you just have to disconnect the battery and it will lose all the settings (pretty sure about that).
"Adapt" is probably too strong a word anyway, it doesn't greatly affect performance.

Thanks | The steptronic trans is driver adaptive, and the "adaptation is restarted each time the vehicle pulls away from a standstill" so I don't think breaking in your car properly will have any adverse effects--see this doc:

Porsche still has the same 2,000 mile recommended break in period for the 997 that they did for the 996.
Of course, some dealer tech, service adviser or salesman might tell you that they break in the engine for you, but that's not so. They do run the engines on a bench before installing them in the car (I've seen this at the factory), but that doesn't break in the engine; and the break in is for the entire drive train, not just the engine.
