Just found out that Showa has made a mobile (cell) phone app to support riders with SFF TAC Showa forks. I've downloaded it (its free!) and it is actually pretty good. You upload your info such as bike, rider weight etc and it generates recommended pressures You then use the app to see how pressure/oil changes effect the suspension via a 'reaction force graph', which basically eliminates the guess work out of pressure changes as you can visually see how a change will effect the fork via the graph, very useful. It also features a 'Setting FAQ' which gives a very detailed run down of how to tune the forks to solve specific issues. Overall a real good app and a much needed tool for SFF TAC users, if you haven't already I'd highly recommend you download it!
