"Lambda"
Does your car have a variant?

It constantly changes with accelerator position. You want 12.5 AFR at wide open throttle and somewhere around 13.5 AFR at idle and cruise. It is possible to go a little higher at idle and cruise but you want to make sure your engine is not pinging. That can be catastrophic.
