Thanks for the info. I was considering buying the OBD-II scan software from OBD-II.com but this package seems a little cheaper and the web page seems a bit more customer friendly. And besides, this guy lives in my hometown. If it sucks I can return it in person. Any more thoughts on this product? Can you log your O2 data? I did read of a few WRX specific problems on the webpage that were supposedly resolved. Any thoughts will be greatly appreciated!....BTW, did you check out this Harrison guy's deer feeder stuff? Yee Haw! What a combination...OBD-II software and deer feeder timers! Only in Texas bubba!
