Cruise Control Lambda Display

On some vehicles the Cruise Control 'Set' button can be used to show the current lambda on the tachometer.  The display is in air-fuel ratio x 1000 offset by 10,000.  eg 14.7:1 = 4700 rpm, 13.2:1 = 3200 rpm

In order for the lambda to be shown the Cruise Control 'Main' switch should be off and the clutch not depressed.

Supported vehicles include all Civic Si, FK8, and 2023 Integra
