This chart shows fuel mixture monitoring of the test R1150 during start-up and during a short ride using the new Nightrider BMW AF-XIED. The top dotted line (in red) represents 14.7:1 AFR, the lower dotted line (in blue) represents 13.8:1 AFR. Monitoring was done by a wide band sensor located in close proximity to the OEM narrow band sensor, ensuring that the measured fuel mixtures were accurate. As the chart shows, the mixture is quite true to 13.8:1 during the test.
