To eliminate the ambient, you have to use the camera in Manual mode with the shutter speed set quite high, and of course the flash needs to be in regular TTL. My cookbook blog explains how to measure the ambient and what to do with the shutter speed to eliminate it.

Remember that spot and cw metering only affect the ambient. Therefore, if you are eliminating the ambient, the metering mode on the camera will have no effect on the image. The metering modes are used only to set the aperture and shutter. The flash sets it's own power separately, and the flash doesn't care what shutter or aperture you pick (as long as it has enough power).
