I am using UV now, thanks! I could only get one version to work, but I see no way of adjusting my wideband sensor analog input. It reads the voltage fine, but I can't find a way to adjust the formula. Looks like different versions are supported, but not my AEM wideband. I found UV scanner v3 online just now. It has a different interface, but on my windows 8 it acts goofy. When the windows are expanded, the top half is missing and I can't move them.
