We are an SCT dealer at CP-E. What questions do you have?
Its similar to the AP. You also have the options of the iTSX (bluetooth/phone based version) and the Livewire TS (big screen version). Does all the datalogging that the cobb does.
Right now, they only do custom tunes for the 14-16 models, and I believe they have a stock preload (think OTS tune) for the 17 fiesta ST (tune for stock hardware) (can also do custom tunes). There should be a bunch of different tuners that can do e-tunes and custom tunes and hopefully more support for 14-17 preloads with time.
Its a little different from the tuner side. You miss some of the Cobb Custom Features (launch control, FFS, burnout mode, map switching, ect). But at the end of the day both Cobb, SCT and other flash tuners give the tuner the tools necessary to make a good tune.
