I don't have a specific BSFC chart for my car, just a "feel" for it based on the progress of my trip mpg with various approaches.
That is how I used to do it too. If you ever drive the 1.0L, things are quite a bit different. I just got back from a lunch meeting and on my highway (55 mph) trip home with some headwind, I had that MAP pegged at 10.5 pretty much the whole way. I let my speed fluctuate and I never got above 60 mph. I only got to coast a few places in the ~10 miles or so. Once I got off the highway, things were quite different. On my trip there things were quite different and I was P&Ging quite a bit.
