You can time the gun, by pressing factory fast in the TIMG menu...thats easy, the only other mechanical timing is seting teh Lug on the hammer.
Take teh bolt out..pop teh correct allen key down the hole, slide hammer back with cocking rod, until you feel teh end of teh hammer (front) then ease it forward till you find teh hole on top.
Do that to adjust the lug height.
Ideally...when you manually push up on the ring on the sear solenoid, it should release the hammer at the very top of its stroke...best done very slowly, pushing with a small Allen key or screwdriver.
As long as the gun can see a difference between open and closed and a ball, your good to go.
Eye sensitivity should be set around 128, but you can adjust this for dark paint.
Other timing can be done, but depends on what parts you have on the gun...if you have QEV's and 44 ram CDEL should be set to around 6ms as a good starting point other wise you may get blow back up the feed tube.
