More power for my Ford E450 32 Foot Forest River Sunseeker

travlr yes you do not have to leave connected. It has other functions and can be hooked up as needed to clear codes etc.

I run a scan gauge 2 from the port to monitor engine points such as volts, water temp etc. They seem to work well together. Mainly used one for my F series and bought another for the van. You can also monitor the speedo and see how far it off from the dsash panel, monitor fuel avg mpg's etc. A handy little tool.

Will let all know tonight when we stop what I find.
