OBD2 Scanner
I've got a cord that plugs into the OBD2 port and you can montor any sensor that your cars ECM sees in realtime and has datalogging abilities. It's called Auto Engenuity and I higly recommend it.
Got it online, can't remember the site...may have been Auto-Engenuity.com or something like that. I bought it a little while ago. Just search for the product on the internet and you'll find it. I like the hell outa mine.
