U381 LIVE DATA Scanner OBD 2 Code Reader~OBD2 MemoScan: eBay Motors (item 390202691565 end time Jun-06-10 03:30:27 PDT)

thats the one i have but any obd2 scanner that does live data should be good. you can also borrow one from an autoparts store, though im not sure if those will have live data or not.
