I start with simple one first
My engine is with code XUD9TE, but XUD7 map should be relatively similar. Only VW TDI map is what I have found to be enough readable for diesel, but that is whole lot different engine.
To get know engine one can read this article:
https://en.wikipedia.org/wiki/PSA_XUD
I find it odd that despite hours and hours of searching, I have found nothing for this engine, even this is very common and not so terribly bad motor. I did try to find contact to car maker, but they seem not want to be contacted, competitor which also used same motor had contact details so I did post question there, but don't know if I ever get reply, so at the moment there is no knowing what kind BSFC map there is for this engine.
Boost starts building up from 1900rpm anyway, below that there is lot less power but maybe also lot less consumption too, who knows.
Tesla, some modern diesels have throttle plate to cut emissions of some sorts, causing higher fuel consumption in progress.
