lugging kills my mileage
For my Subaru, I noticed that I get better fuel economy in a pulse if I make the same amount of power at higher rpm vs. lower RPM at wide open throttle plate.
In short -> 3/4 engine load at 2000rpm is better for me than full load (0 vacuum) at 1500rpm.
I have kept an eye on air to fuel ratio and they are always stoich so long as i don't exceed 3500rpm. the only difference I see on my instruments is higher ignition timing at higher RPMs / lower loads.
Monitoring the "horsepower" gauge and trying to maintain a steady power output has yielded better results than keeping a high engine load during the whole acceleration phase.
Just wanted to share my results and get some feedback. thanks!
