I was bored the other day and i was lookin up stuff for my car's computer and i found http://www.obdii.com and i was looking through there and they had a link to this thing called the autotap http://www.autotap.com/products.html . apparently you just plug it right into your computer and you can view and set like 100s of different variables and get power graphs and all other kinds of stuff. I was just wondering if anyone had one of these or knew if they were worth the 300 bucks cuz i think i might buy me one as a christmas present.
