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
