Rather than setting the max ISO, you should set the minimum shutter speed under AutoISO. Indeed setting the max ISO to 1600 might be the reason for the blurry pics for the camera will then select longer shutter speeds in order to expose correctly. You need to understand that AutoISO is an ISO-minimizing function. It will try to set the lowest shutter speed required for i. proper exposure and ii. satisfy the 1/FL criterion.

The reason for blurry pictures is shutter speed that is too low.  Setting max ISO does just that, keeps the ISO on auto but limits it to max value. If you shoot on Tv mode, which is wise for BIF, then shutter speed is maintained sans the effect of exposure compensation.
