Load Questions from a newbee

[steve ravet]

It's an estimation of the load on the engine.  It's not just RPM because
you can be at high rpm with little load, like on the highway or revving
in neutral.

It's also not just throttle position, because you can have WOT without
load, like revving in neutral.

It's basically airflow divided by RPM.  airflow is either measured by
MAF, or estimated by MAP.
