But really, I like to see if the car is doing weird things. There was a time when my AFRs went all kind of wonky on me... Nothing crazy lean, but 16's under gentle acceleration, 18's at idle, etc. The more readable data I can have when something happens (to a reasonable extent), the better I feel I could diagnose a potential issue or match tangible data to the intangible feelings to help an expert with diagnostics.
