I was using DFCO and braking as little as possible before I started coasting, so the combination of both is inferior to engine-on coasting.

Yes, but I think DFCO has a strategic purpose for us. Going down a steep grade while coasting is not a great idea from a brake-overheating POV. However, if I can get engine-braking + DFCO on the downhill, I can avoid using my brakes and risking dangerous speeds.

If I had a fuel-injector cutoff switch, I could use it for manual DFCO.
