Hello i am going to buy Dyno Quick shifter Sensor , and rod but i know that for 8 injector motorcycles it needs Expansion module(Q.E.M) also .

But i am going to buy Secoundary Fuel module also , and could not undestand if i will buy it after that i dont need Q.E.M or its deferant things ? I mean does secoundary fuel module aslo includes Q.E.M functions fully ?

There's really no need to adjust the secondary injectors on a stock engine bike. If you feel you need to adjust the secondaries,the preferred method would be to set the injector balance 50/50 through the ECU vs adding on another piggyback unit.

If you set the balance 50/50 then the secondaries spray on the throttle plates. Normally secondaries start spraying when throttle is almost fully open and rpms above ~7000rpm...

Better to get a secondary fuel module for the quickshifter, then you also get the fueling better.
