Anyone able to understand this
 

So Ive been looking for a bsfc map for my car forever now. Honda Civic EX 2007 M/T.

I think I have found it but Im not entirely sure.

Here is the link . Technical Overview of Honda's new R18 i-VTEC Implementation

...sorry, but none of those illustrations is a Brake-Specific-Fuel-Consumption (BSFC) curve.

A BSFC map should look more like this showing consumption at many different engine loads. That is a nice engine though as it is able to shift back and forth from a low powered Atkinson cycle to a high power cycle.
