What does speed air density mean?

That refers to a tuning method where the air flow calculation comes from engine speed and manifold air density. Other methods for calculating / estimating the air flow includes measuring it (Mass Airflow Sensor - MAF), or Alpha-N tuning, based on a fuel table from throttle position angle (alpha) and engine speed (n as in N revolutions / min).
