I have a laptop and like the idea of being able to track and change settings on my ECU. The Scan Gauge II would be a very nifty tool to have to watch instant mileage, etc., but doesn't offer any method of changing settings and is pretty expensive.
What are the best and where can I get a cable that goes from the OBDII connector to a USB or serial port? Where would I get the software to read these settings (I'd assume some [i]simple[/i] software would come with the cable)?
I saw a post where someone had an ELM323 ISO OBDII Interface, but googling only comes up with stuff overseas. Going to [url=http://www.elmelectronics.com/connect.html]ELM Electronics[/url] shows that I would need a ELM327, which is the "universal" one.
