Just wanted to throw this out here in case you didn't see me mention it in my AccessPort post. It's a pretty awesome little tool, and 100% free. Logs a ton of parameters to .csv files, or you can view the data live. Requires a serial<->OBD2 cable. The AccessPort cable works, or you can get one from the OpenECU guys for $60-70. Been having a lot of fun with it. TARI site Single user friendly too... it starts/stop logging when you push the defrost button, so you don't need somebody to ride with you and run the laptop.
