I like a smooth, quiet technique, so I tend to accelerate at pretty light loads and shift very early, like 1.5k RPM in city driving. I realize it's not the most efficient engine operation, but I think acceleration style is just about the least important thing to focus on (except when you're trying to pulse & glide). I will accelerate faster on an open road.

It's all the other stuff that counts the most: minimizing brake use, killing the engine and coasting in N where appropriate, etc.

Considering the pumping loses reduction, and eco cam operation of our engine, you think is best to pull fast/high load to get to cruising speed sooner, or to pull with low load? shifting at 2k? 2.5k rpms?
I'm not convinced the savings of the eco profile are worth the penalty of fast acceleration. It's certainly not a ~33%% gain like lean burn in a gen. 1 Insight. Also, once in 3rd gear, I can accelerate on the eco profile.

I may try again to get test data with the eco profile on/off, but because of the cruise control problem, I really need another set of eyes & fingers in the car to do it right (safely).
