Yep, sure does! Its called engine overspeed protection. Cant remember exactly where it is at, but just scroll slowly and you will find it.
It has a rpm and speed limit to it. It will shut off fuel when it reaches those. The bin I am using is set to cut off fuel at 4800 rpm. And speed is set to cut fuel at 96 mph.
