as far as i can tell, all that is is they took a pinout of the tcm and how it shifts the tranny, and programmed it into a simple microprocessor with a few buttons to let you have total manual control of the tranny. anybody who knew how could do it, the info is readily available, but i think i heard it was 400 bucks?? yikes. id rather just have autostick.

anyway, this is only conjecture, but the tcm determines how hard you are pressing on the gas, and thus (somewhat) shift firmness, from the tps signal. now i think ive heard that there isnt an upper limit on what the pcm will recognize from the tps. iirc, the tps is on a 5 volt reference but never gets much higher than 4.2v or so. you may be able to rig some thing up so that the tps signal line connects with the reference line at WOT and thus you get 5 v and presumably firmer shifts. you may be able to hook it up to the torque reduction line from the pcm as that only works when you are shifting, so it would be convenient and automatic, but frankly i just put this crackpot theory together in my head just now so i may be totally off on all of it. lol
