Hey, was wondering if there's a way (well, i know there is, but...) to read the data from the ECM/ECU and what ever other computer parts/information that is provided to be displayed on a laptop or PDA screen. IE. water temp, oil pressure, rpms, shift points, emissions, etc, etc, etc. Basically, every part of the system to know "exactly" what's going on with my car. I just wanna know what's all set and what all there is goin on with it.

thanx
