Do all the scan gauge II include the x gauge feature where you can add the extra gauges? Or was this an add on in later models? I can buy a used one for $100 but if it won't read everything I'd rather have a new one.

 

Go to Scan Gauge's website, there are some 6.0 specific inputs that must be manually entered. I don't know if SGII means X-Gauge or not.

For a little effort, the SGII is a neat little piece. I really dig mine. Give me a few days, I'll do some digging and find some X Gauge settings that aren't in the breif in the owner's manual. I've been thinking about using the mpg settings, find out if it's a "Lie-O-Meter" or not.
