Hi.

You know I wanna figure out with you one thing. There is a guy that prompts to drive like that, concerning the BSFC and in elimination of the pump loses, by doing the following. Don't forget that we are talking about the electronic accelerator pedal.

He rises the revs up to 3000 rpm, on the first gear, and then, with the further acceleration on the 2, and 3rd gears, by giving 80% instant push of the pedal, on each gear, he is saying by doing that he opens the throttle blade fully, and that it is the right economic way to ride concerning the elimination of the pump loses on it, with the best BSFC. But we know that the car do not, with e-pedal, do the things it do with conservative pedal with wire. And do not accelerate righ at all for a long time.

What do you think? I know what I think on him...., but want to know your opinions.

And we all should know that, the fuel is less burned for economy by fast car acceleration, in full but not that fast accelerator push, to get away from fuel-hungry gears asap.

Toyota A25A-FKS BSFC image

I haven't seen plots for Toyota's Dynamic Force Engines posted yet. Apologies if I missed it somewhere. This is the plot for the 2.5 liter version from this document:

That is one of the engines that Toyota refers to as "Dynamic Force". It's an Atkinson Cycle GDI engine with cooled external EGR designed for non-HEV applications.

I am (impatiently) waiting for the same chart for the M20A-FKS (in my 2020 Corolla), which is the 2.0L little sibling of the 2.5 A25A-FKS. From everything I've seen the M20A is +/- a scaled down version of the same design, so I suspect the BSFC map will be very similar.
