Thanks Steveo! I'm not much help but will take a look and test. I'm always messing around with it some how. I finally ordered a WB and excited to see how it does with the data. I have never had a WB in my life. I've alway used my nose and spark plug readings but I'm no pro. I have read they need to be calibrated. Is there anything special I need to do to get it calibrated for EEHack? I won't have a gauge only using EEhack with the WB O2.
