Sorry I'm intruding, I also in the post,
I am in my car a 535d 6 cylinder in-line with edc16c35
ori has 26° of advance and 29° of the time injected, and then inject
3° after tdc, of course at maximum rpm and load.
Now I've tried to make a mod in which spremevo the most out of this engine,
the result is 38°, injected at the maximum and decrease in the rpm lower and lower loads.
Now reading that the alfa 159 also comes with 40° of advance is of the soi, which is injected into and knowing what comes my,
my it seems strange that you are not able to exceed 25°.
I wanted to point out that, however, I am also of the idea that an advance excessive damages to the bushings for the too much pressure generated
in my case, an increase of 200 Bar, however, that it is also true that at high speeds, for the rest of the table, we are well below 25°, we say that my increases
on the soi,main, and post is not disaccostano of more than 5° from the original in the areas of cruise, perhaps it is slightly delayed at low engine speeds and loads to make the engine more elastic and park
