In other words, no time component
RPM = rev/min which in units might boil down to 1/time, but you have to divide by 60 to get to that point which is pretty important. Also maf is generally measured as g/s not kg/s on these cars. While revolutions might not seem like a unit to you, it's important because the ecu needs to make a comparison between the 2 axes. So load boils down to g/rev and the way it compares that to RPM, without the /rev in the definition of load you really can't make a comparison to anything. But yes not really a time component. Just related to time through revolutions.
