Every hypermiler should study the BSFC plot for his engine. I wouldn't bother trying to hit the <215g/KWh zone instead of the <235 zone, but there are some trends you need to know about. It shows you the zone you want to stay in: ~70% throttle, <3000RPM. Unfortunately, that overlaps with the zone where Assist kicks in. Stay out of Assist, because any energy you remove from the battery needs to be paid back.
An
IMA inhibit switch allows you to operate at wide throttle, low RPMs without draining the battery.
These readings were taken on a chassis dyno, which regulates RPM. Throttle position was modulated to achieve different values of torque at any given RPM. I presume the bottom five data points are with the throttle fully closed, i.e. at idle.
The ScanGauge makes an educated guess based on the amount of air entering the engine, RPM, displacement, and the output of a few other sensors. It can't actually measure fuel consumption or torque. But LOD is how much torque the SG things your engine is producing, as a percentage of avialable torque at your current RPM.
