In TunerStudio while the engine is running I can see the AFR on a gauge labeled "Air:Fuel Ratio 1" and in my SD Card Datalogging setup, I have the fields AFR, AFR 1 Target, and AFR 1 Error selected, among others. But when I look at the logs, I see sensible values for AFR 1 Target and AFR 1 Error (considering what's coming next), but "AFR" is pretty much a flatline around 0.3. Any ideas what I'm doing wrong?

BTW this is an MS3X with a Spartan Lambda 2

Can you host and link the log?

If you have just upgraded the firmware, try removing AFR from the SD card list and re-adding it.

Haven't done a firmware upgrade since the car was first set up, but I'll try that.

Removing and re-adding the AFR field (and writing the settings to the MS3 in between) fixed it, thanks Matt!
