Try this

You may be losing one F value to the ceiling when bouncing flash, but the flash is compensating for this with more power by metering the light reflected back from the subject. Therefore I don't think it is correct to use a lower F-stop value on the camera than the flash. If the flash is set to F 5.4, then put the camera in manual mode and set the aperture to 5.4 and set the ISO to 100 so it all matches. This is true whether you are using direct flash, any lumiquest configuration or bouncing from the ceiling.

Now there are only two variables left to set. One is the shutter speed, and this is not such a critical value with flash photography, but you can experiment and find something that gives good results. Start out with 1/125 or faster and see how that works. Experiment up to about 1/1000. The other variable is the bounce angle. You need to consider how high your ceiling is, what color it is and how far from your subject you are. If you have a normal residential ceiling height of 2.5 meters from the floor, the ceiling is white and flat, and you are about 3 meters from your subject, then you should be bouncing off the ceiling at about 90 or 75 degrees as indicated on the flash's bounce angle indicator. If you have a significantly different ceiling geometry, you are on your own.

You should be aware that this is a powerful flash and you may not be able to avoid overexposure at close range with the flash pointed directly at the subject. For this reason is also might be smart to disable the auxiliary fill flash until you get this sorted out.

If you do not have strong backlighting and are still not getting good exposures, then make sure that the meter on the front of the flash is not obstructed in any way. Also make sure that the camera's flash settings in the menu are set to normal (I think the V1 has such a setting). If this still doesn't work, then there may be a problem with the flash.

Oh yeah: of course I am assuming you have fresh high-quality batteries installed in the flash and you are allowing it sufficient time to charge between flashes.
