I guess I was starting to get the hang of carb tuning, after all -- while tuning the ECM fuel mixture for the first time I could pretty much tell by sound and feel when I was rich or lean without looking at the sensor/BLM/etc. It was kind of neat to sort of check my mental calibration. :)

Of course I couldn't divine the KPA by feel, sound, smell, or ESP... :) So not much chance of actually tuning this thing without all the handy numbers and cells...
