    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

    I can only find lines climbing immediately after, and at the end something that has a value of 22 (the maximum degrees golds) but I don't know if it is that... you 1d1430..
    I pray you to the point of showing me this mystery that we are out crazy!!
    They are not at the pc now, however if it is a 8v is not a 30 degrees fixed but is made to the lineup. This is the first map after the advances, you can't get it wrong the bp immediately after the limiter.
    On the 8v size 25.92 degrees, it seems to me

    I have never mapped a 159 and I have never seen a file,
    as I wrote, I found people who spoke
    of these famous 40°, and I gave the example that between my 26°
    and these alleged 40° to say that it is not possible to get there it seems strange to me.
    I open a small parenthesis, it depends on the construction of the bearings, i.e.
    how many MPa resist going to anticipate the injection may be, as of course they all say
    a damage or not.

    However, you have already mapped the 535d? it is only a question to confront us

    Made a calculation on the basis of the rail pressure of how many degrees you have, and you remove all doubt.. normally on a 1,9 (1910) with the rail pressure maximum 1700bar does not exceed the 38gradi that murano and usually the difference of the grades is divided by two and is added to the pms, and then say get to 40gradi sounds really bullshit..

    from what I was taught by a little (not na the top, but the ioc slammed the horns strongly) do this calculation..
    for example, on the injection ori to 4500 (the regime of bp that I have on my edc16c39)

    4500/60/1000000x360=0,027 x times to 80mm3) the time and gold to 80mm3 to 1600 bar are 975 microseconds = 26,32 degrees and the duration of injection ori
    injection mod always at 4500rpm:
    4500/60/1000000X360=0,027 x times to 100mm3 and times mod 1700 bar (new bp is created) and 1180 microseconds = 31,86 degrees
    At the end is the dfferenza and you get the difference in degrees of inj that should be centered for proper combustion, but then you do more testing and log that in calculation.. often the walls or maybe ingurgita some degree..
    I hope I have not wrong calculations but I would say no

    forgive me, I was wrong.. the degrees are not 38, but 32.. sorry!

    At 5000 rpm, or a pressure of 1600 bar for a time of 979 uS
    and inject really 73 mg (86 mm^3), I personally do not use the bars for the calculation:

    the formula I use is (979*6*5000)/10^6=29,28

    The proof of concept to see if the formula is right is this:
    Knowing that at 5000 rpm for 1° takes 33,33 uS,
    you 979/33,33=29,28

    Having how to map the main 26,50 I know that is after the tdc 3°

    Stock injects 86mm3 to 5000 rpm?

    for Jack, the car injects 86 mm^3 ori

    for Tranky, listen to you crucciare with a myriad of accounts, if you follow what I told you, I do it before
    making the account on your are about 22°, and is calibrated to 4000 rpm and 500 rpm in the 147
    thrown.
