+1 for this request, i just bought 2 EAFs for my SCTs and found after installing them found this issue and got here to this forum. I agree the best solution is the x steps per count, in fact some others focusers use that. In my C11 i had to use 2 steps
Just an example, this other focuser has also a limit of 65k values, however it implements the configurable steps per tick value, and also in my case has to be 2 to cover a range of 114800 steps (59000-1600)*2 to cover the required turns. It originally defaulted to 1 but if you needed to expand the range you an apply an arbitrary integer multipler at the expense of decrease of precision) I think this kind of solution just requires really small development and can easilly be implemented in EAF Firmware, as other focusers do.
WOuld like to get feedback from ZWO to see if i should return my two newly purchased EAFs or not. This is a standard feature on all other decent focusers.
