Once you get the Tunze cables, check out my Tunze setting thread. I documented all my profiles and programming for my Tunze's on my Apex and described everything in detail. Read through the entire thread as there are programming updates along with other information that should really help you understand what you are doing. You will be amazed at what you can do with them once you get an understanding of what you are doing with the Apex.
Anyway, here is the thread. Good luck and enjoy your Tunze's. 3 years now and my 3 Tunze's haven't skipped a beat and I beat the cr@p out of them!
