this is the pipe you need for twin Z32 on big single application, made by trust, very nice piece of kit

then on the powerfc as the others have said read the PFC FAQ
in a pinch you can choose VG30 and it should run and idle OK
if you are still having issues with VG30 selected view ETC, SENSOR SW CHECK on the hand controller and check out the values for AF-1 and AF-2 - they should be very similar and no black highlight
