Here is a (unadvertised?) feature in FastWorks. You can use the output from your Wideband O2 sensor and patch it in to the OBD plug. FastWorks will then be able to integrate it into your datalog. I believe it's optimized for AEM EUGO, but Phil has said other systems can be used though it might require adjusting a configuration (not by user though).
First step is order an OBD-2 female pin. I did this by ordering a whole OBD-2 plug from China through Ebay. It was a whole $3 or $4 shipped. I would suggest this method because that way you will get plenty of extra pins in case you ever do something like this again or help a local member. It's also good because it will come with 2 new retaining tabs, which means you can destroy the one that's in the current OBD-2 port.

Run a wire from the Output of the EUGO and crimp one of the OBD female pin on the other end.

Note that end of the pin is shaped a certain way.

Detach the OBD-2 port from below the dash. We are wanting to stick our cable into pin #8.

The top retaining tab needs to be removed. The way I did it was to cut out the little triangles that lock into the housing with some small wire cutters.
Then push the new wire, being sure to align the pin the same way as the others on the top row.

As a reference. You can buy Bosch Wideband O2 sensors for the AEM EUGO from nearly any autoparts store for a very reasonable price. Order Bosch part 17018. This will have the exact same sensor and connector plug.

They are $50-60 and more importantly, can be picked up right then and there.
Once that's all done, all you need to do is enable tactrix.adc8 in the View > Data List menu (towards the bottom).
Sample datalog output. *Note* that the FastWorks software samples at about 20-30 frames per second, so this is only a couple seconds worth of data. The whole datalog was less then 30 seconds long and is almost 2000 lines of data.
*My TargetAFR column is custom added, its a formula of engine.fuel.targetlambda column multiplied by 14.7 =(14.7*D2)
