Shot with the E-M1 and 12-40mm @ 12mm on a tripod. I used Manual mode with manual focus set to infinity. Setup the EM-1 in Live Time mode and it worked great. You could see the fireworks coming to life on the screen. Aperture was f/10 and ISO 100. I would probably use ISO 200 next time for less clipping. (ISO 100 is known to have less DR than 200 - more clipping) Long exposure noise reduction was turned off. Forgot to set the color temperature/white balance to Tungsten or ~3000. Shutter shock set to zero, but not sure this mattered. Turned off IS since I was using the tripod. Waited until after the initial launch/explosion to open the shutter and closed it as fireworks were peaking. Live Time was made for this kind of shooting! I tried using the Oly Oi Share app on my iPhone and my Android Tablet, but the lag between me pressing the shutter icon and it actually closing the shutter was much too long. Exposures varied from 3 to 5 seconds.
