EG. in the Saturn chart, 7/9 throttle @ 2000 RPM looks like it would put you squarely in the 250 g/kWh island.
That's what I was trying to say in the shift timing thread. 7/9 = 77% of max torque (or load). Examining a bunch BSFC maps, and measuring the extents and center of the peak efficiency island, I found the average center point to be 72% of max load. Hence the question; Can we believe the LOD output on the scangauge as a good indication of engine load?
