E3d V6 firmware modfications for umo+

[Migo 1]

Hello, i installed E3d V6 hot end with mk8 feeder ( bowden Design) for my umo+ but i have many problems with the extruder movement , leaking , escaping problem with the feeder what am i supposed to modify ?

 now that it goes further than heat bed area sometimes , it moves so fast sometimes making the belt vibrates , acting up during printing , is that a firmawre problem ?

and what are the modifcations  for the firmware to make my umo+  work proberly with that extruder
