Load is one of the parameters an engine uses to calculate fuel and ignition timing. It's pretty much a function of rpm and throttle input.
At very high rpm with the throttle barely open there is very low load. At low rpm, wide open throttle load is very high. Think of it as a measurement of how much work you're asking the engine to do.
Trims are offsets that the ecu applies to the base fuel tables based on sensor feedback. These are 'learned' or cached over time. High trims are bad.
