Does anyone know how to do this on our trucks. Using my shops scanner it shows air fuel ratio in percentage, not in the typical x.xx/x way. I asked a few people who are really good with the scan tool (Snap On Modis) and they said thats the way nissans ecu interprets the air fuel ratio. Anyone have an idea? I'd like to see what the truck is doing at WOT, but the numbers make no sense to me.
