What I want is something like the dashdaq that was mentioned on the page Who linked to. I like the data that the scan gauge provides, but I want a realtime (or near it, I understand that realtime would update way too fast) data stream to an external computer which could be used to display and analyze the data. As I understand the scan gauge's only interface to a computer is to disconnect it from the obd2 port and plug it into a computer to download a batch of data. Basically, what I'm looking for is the cheapest/best/easiest way to interface the ecu to a computer plus any recommendations or advice from anyone who has already done this.
