Whatever strobe you're using outside the housing is controlled by the strobe on the camera inside the house via the fiber-optic cables. Since the maximum sync speed on your onboard strobe is 1/160 of the second that's as fast as the camera is going to fire regardless of what shutter speed setting you dial land before you pop up the onboard strobe. The failure of the external strobes firing maybe a result of not having waited long enough for the internal strobe to recycle.
Phil, it was only my D2000 that wouldn't fire consistently. I thought I had solved it by switching to auto but it was flaky on my second dive as well. When I wrote stuck at 160, I should've clarified that the camera would not let me set it faster...I only had 160 and below available. When I took the camera out of the housing, I had access (at least setting wise) to all shutter speeds. I will mess with it some more today. Thank you.
What Phil told you is correct, the max shutter speed that you can get with the strobe extended is 160.
If you want to go higher you have to go to RC mode in the menus and use specialised Olympus strobes. . .
