Reconfigure speedometer?

[aris_unlimited]

I was thinking about upgrading my wheels and I was just curious if it is possible to recalibrate the speedo for the wheel/tire difference. I know that with my blazer I can do it with just a programmer. I was wondering if there is something similar for the 350z's?

I think I saw similar question somewhere and responses were negative. It was like... you have to swap with correct resistors and stuff. It sounded pretty tough.

Well that kind of sucks. I was hoping to keep the mileage/mph accurate after I swapped wheels/tires. Oh well.

Although I suppose I can ask the dealership what it would take to do it, because I was thinking about going with the 18 in nismo wheels.
