This might be a stupid question to you guys but,I was wondering what kinds of programs were out there? Where i work sells laptops fairly cheap to employees and if i were to get one would i be able to diagnos my car problems with the laptop and obd-II software? I'm not familiar in this realm of tuning. Will i need special equipment besides the laptop or a certain kind of PC? The kind available to me is a IBM 770 touchpad or thinkpad(can't remember)i'm still fresh in the computer world.
