I think the relative definition of load is the percentage of air flow compared to WOT at that engine speed, and the absolute load is the percentage of air flow compared to cylinder displacement, which is like volumetric efficiency.

About PID Calculated Load Value » OBD-II Resource

Here's some good discussion on it.

If you have a BSFC map, you can use that load and rpm to figure out engine efficiency.

You need to cut back on your electrical consumption. Consider turning off the PC when you aren't using it, and switch to CFL bulbs.

The Prius doesn't idle, or at least during the few times it does, the data isn't relevant because it's in warm-up mode, and purposely wasting more fuel than it needs to.

My Acura TSX 2.4L I4 engine idles at 25% engine load with the manual gearbox in neutral, and parking brake set (no brake lights on), no HVAC. Timing advance bounces around 9 degrees, but I'm also running the minimum octane instead of the recommended 91. Fuel consumption is 0.18 gal/hr.

The relevant info is instant fuel consumption.

I'd sure be curious if there is any difference from when I had the stock pulley ratios installed. I didn't find this site and get a gauge until after I had swapped it out.

Hospital? Nuclear silo? Server farm? Really big subwoofers for your garage band? Where do you feed that beast?
