I have one in my diesel truck (f350) and it monitors a lots of things. Put one in the rv (e450 v10) and it does not monitor much. Wrote the company and asked why and they gave an answer of basically its for diesels and not designed to monitor the same things with the gas engines in mind! So can only monitor some of the things I do in the diesel.
You might wsant to go to their website and check what you want or write them and ask specific questions. IE no EOT in gas engines were a couple of others cant remember right now.
