Just to update and summarize for anyone that skips to the later part of this thread.

As I mentioned, everyone NEEDS to buy an OBDII tool. For as little as $30 you can have a tool that does everything you need. Actually the cheaper tools have capabilities to record data to a CSV file so the data can be graphed as needed. See some of the graphs below.

How do you get a tool for $30 or under.

If you have an Andriod phone or tablet, a $5 App and a $15 interface. Either Torque Pro or Touch Scan.

If you have an iPhone, iPad or iTouch, a $10 App and a $25 interface. OBD Fusion seems to be the cheapest IOS solution.

If you have a Windows laptop you can get ODBWiz with interface for under $30. From Amazon, link at the beginning of the thread.

Also ELM has their own software provided with some of their OBD interfaces called ScanMaster ELM.

Some other low cost options that support Emission Readiness, Freeze Frame and Live/Real Time Data-

$33 - Autel AULMS310 -

$45 - Autel AutoLink AL319 -

$52 - Autel MaxiScan MS509 -

$79 - Autel Autolink AL519 -

$90 - Autel AutoLink AL439 which is a combination scan tool AND Voltmeter -

$115 - Autel Autolink AL539 which is a combination scan tool AND Voltmeter with battery and alternator testing capability along with graphing and recording OBDII data streams -
I have not used these specific tools, but it looks like they offer most features that are needed.

And you can get a very good stand alone OBDII scan tool for just under $100, or step up a bit and likely get a very good tool for around $160.

Search Launch CReader 123 or CRP123/129 and see what these can do for over 30 different manufacturers for between $100-$200.

And to the folks that think they MUST HAVE BMW specific tools and software, do everyone a favor and do not buy any of these tools without at least having purchased a generic OBDII tool that supports Emission Readiness Monitors, Freeze Frame and Live/Real Time data and preferably data logging and recording. These generic tools are FAR more useful than most people realize.
