	;Engine load: Also known as relative cylinder charge. It represents the percentage of air (compared to standard density) in each of the cylinders. 100% load means each cylinder has the mass of air as an equivalent volume at standard density. Ingested air mass is calculated from [[MAF]] value (mass/time) divided by RPM (1/time), divided by two to yield a mass. Standard mass is calculated by engine displacement (volume) times standard density (mass/volume). The ratio of the two masses is load. It is used in real time to determine all other values including boost, timing, and fueling.		;Engine load: Also known as relative cylinder charge.

Standard mass is calculated by engine displacement (volume) times standard density (mass/volume). The ratio of the two masses is load. It is used in real time to determine all other values including boost, timing, and fueling. In normally aspirated motors, load will rarely exceed 100%, but in forced induction motors, load exceeding 100% is expected.

	;Engine load: Also known as relative cylinder charge. It represents the percentage of air (compared to standard density) in each of the cylinders. 100% load means each cylinder has the mass of air as an equivalent volume at standard density. Ingested air mass is calculated from [[MAF]] value (mass/time) divided by RPM (1/time), divided by two to yield a mass. Standard mass is calculated by engine displacement (volume) times standard density (mass/volume). The ratio of the two masses is load. It is used in real time to ~~control~~ all other values including boost, timing, and fueling.		;Engine load: Also known as relative cylinder charge.
