First off, as you know, setting a limit higher than 30 mA is not “officially supported,” but we’ll do our best to help you out. :)

For maximum current, solder together the two connected (or all three) pins of VR1 and VR2.  Then, put the selected resistors (one per driver chip) into RA1 and RA2.  We are not *aware* of anything else in the circuit that will prevent you from going all the way to 90 mA (besides the temperature of the LED driver chips in free air), but you are in somewhat uncharted territory.
