OK!!! I have the official solution to the rf-602 nikon transmitter issues!!!

All I've done is tape up all the contacts bar the center and outside contacts. the green light never comes on, but it syncs to 1/160'th every time and with the button tweak you can get 1/180th every time too. No mis fires, no messing up or around.

Now i can use my flashes in public without being ashamed or looking un professional (even though i am!)
