On a scan tool is viewing and recording the enhanced OBD2 live data useful? If so for what. I'm looking at a new scan tool and its a difference of 30 bucks. Wife wants me not to spend that 30 bucks. Info please

lets ask a BETTER question. What use is only having the codes? What can you do with that information?
Are you GOOD (beyond typical professional) at diagnosing by code only?

Live data is a must have for more complex problem or intermitten concerns. Had to record about an hours worth or data to find a problem once. THat was some major window time.
How To: OBD2 diagnostic strategy
Plenty of talk about what type of things you can see with livedata, especially if you can graph it out over time. I don't think I could do much in the way of driveability diagnostics without it.

Some 2003s,2004 and current vehicles are can vehicles.Some 2003 Fords are can.If the scan tool does not have can which stands for controled area network,you are screwed.

CAN is a network topology, not an interface. You'll have reduced functionality with the scan tool (probably limited to generic OBDII data and slower data rates), but that's not quite the same as being "screwed". Chances are pretty good that he'd still be able to access stored codes, and generic OBD functions.

What scan tool lets you see live data for 30 more? You need to be careful with these scan tool claims on live data or you will be sorely disappointed in what you get.

Didn't he take the "CAN class"?

I used live data to check and verify a friend's fuel trim was off. If we didn't have access to this data, we would have never known for sure why the car kept tripping a lean code. We ended up replacing the MAF sensor and fixed the problem. Just this one time alone probably already paid for the scan tool itself considering taking it into a dealer would cost a lot more.
It will be an extra $30 well spent if you ask me.
