Fuel injection is electrically and computer controlled while carburetors rely on air pressure changes and is completely mechanical. Why did they stick with carbs for so long? Lots of reasons but a few: Fuel injectors allow for more power so giving every car a boost was a delibrate decision - NASCAR already has other speed-reducing technology on purpose. Switching also meant every team spending millions and redesigning their entire engine to take advantage of the new tech. Carbs had ossified so teams were pretty level on this front indepenent of money so switching also would give teams with money money a bigger advantage.
