No it's only for Ford, Lincoln, Mazda and basically anything built off the Ford designs. It wouldn't work with Chrysler. There may be something similar for Chrysler, but I'm not aware of it because I don't own one.Looks like I'll try the ForScan lite on my phone. If I could find a suitable ELM327 locally... Prolly ebay tho.
Could something like this also be used on a 2007 ish Chrysler? I could hope...
You won't be able to change anything with your phone probably. You have to use Forscan for Windows (not, for instance, Android Forscan) to change anything. You can only use the mobile versions to read settings, not change anything.
