LOD is the % of maximum engine power you are currently using at the RPM reading you're currently at. Think of HP and TQ availability at that RPM point and how much of that power you are using. The ECM reads air volume in, exhaust temps, thottle positioning, and other sensors to determine the load and how to optimize the tuning of the engine to reduce the load without sacrificing the power needed.
That's my 30,000 foot view and I'm sticking to it.
BTW, it would be very cool to track and record FIA and TPS from different engine modded configurations to see if a CAI really is a CAI. lol! Where mine is still original as sin, I can contribute ti the FIA reading ar both highway and city driving speeds. Also we can measure for outside temp ranges. My morning commutes are still in the 20s, and today the ride home will be in the 60s. I'd love to chart CAI vs. stock readings to see how much os a difference different ones make. Ya, purely unscientific as it's not perfectly controlled, but it sure might be an interesting read at the end.
Am I nutz? Maybe you might not answer that right off. heh...

*FIA: What are you all getting for Temps, and with what intake?
I am averaging 78-85deg. with my true fllow at cruising speeds.
90 deg. if idle for a while. This was all during a 68 deg afternoon.
Figured the best way to know whats good or bad, is to know the norm...
