Has anyone heard of or used a ScanGauge II? http://www.scangauge.com

 

if you dont already have a scan tool I'd might get it, but I already have one so I'll pass, other then that it's just like that new Greddy Informeter thing

 

I've used the scanguage I. I thought it was real easy to use, and I might buy one eventually. If I remember right, it lets you scan rpm, mph, mpg, a/f, and stuff from a lot of other sensors (don't exactly remember which, but the manual is online). It also has a trip computer that can log values for everything over a period of time - like you can check your gas mileage over a month, or whatever. You can also use it to reset MILs.
