I have installed the latest (Obd-Diag .01-.02)software and am using a elm 327 interface. Everything seems to work but all units are in metric and I cannot seem to get the lower of the two charts to work, I believe this chart is for an O2 sensor. I tried their website (Strange distribution) but it is in German. Does anyone know of a how to get help with using this software? Thanks in advance for any help. John
