but certain things like AWD torque distribution and valve lift is based on throttle input. Yes I know about BSFC charts but there is none for my engine as they are company secrets now. experimentation always has not delivered solid results. whether I shift at 1.5k or 3k 80% load I still get identical crappy mileage. but if I forget about engine speed and keep a constant power output of say ~40hp I get better mileage. its hard to maintain 40hp anywhere on the powerband except at ~2k rpm. below that it leads to full load and enrichment and above that power output shoots up and throttle becomes more sensitive.
