Well...there's no easy answer. There is a member here who has helped me a great deal, but I dont have his permission to use his name, so I won't. What was suggested, and I did. Find a copy of TTS for dummies. DO NOT be insulted by the title. I downloaded it and printed off a copy so I could read as I execute the operations. This helped A GREAT DEAL. The TTS manuals also are VERY helpful, but are written assuming one has a really good understanding of all the tables, and a basic understanding of the process. I have a better understanding now, but so far it has been a pretty painstaking process. It is methodical. Step by step. One cannot take shortcuts because one does not understand what's goin on with the step one is on. Although over time, and MANY flights, I was able to develop a pretty good tune for the bike in its then configuration. Recently, I installed stage 2 cams from HD, and the tune that I so painstakingly developed well, its crap now. So, without a good base tune, one must develop their own, and if you think tweaking an existing, close to right tune is difficult, this tops that. However IT CAN BE DONE. I still believe TTS is the BEST tuner on the market, without question. I may, and stress MAY have a professional do the tuning for the cams.
Once, when I was super frustrated I looked into another brand, sold through fuelmoto, because they advertise "we have base maps for every configuration ". The response I got was "we dont have a map for that. S2 cams are tricky and we advise dynotuning" . I can forward you the emails if you like. So I went back to the best, and will get it one way or the other.
Good luck
