with a qev in an ion, first off...you need to cut the material from the plastic body, in line with the qev, to the front, about 1/4 inch width, to allow removal of the plastic body for access to the bolt and fof correct fitment of the qev. it replaces the front banjo fitting on the main tube.
then drop the dwewll right down, as it describes in the manual...approx 52 bleeps, till the light dont flash when you press the button...then raise the dwell, up to 8 bleeps an try it for shootdown...if any problems, raise it a bleep at a time till it works ok.
