I remember there was some readings the dash display posted that we didnt know what they were for.
Sorry if this is a dumb post like all my others.
It's not a dumb question. It would be nice if it was that easy.
, there is no LCD readout in the scrollable odometer display that corresponds to any kind of A/F reading or voltage that could be used to compare with a separate gauge. The "odometer" diagnostic function gives data that pertains mainly to instrument cluster readings/sensors.
It is missing the key ingredient which is the wideband sensor in the exhaust flow - an O2 sensor won't do - which generates the voltage read by any gauge.
