    But if the error is not in the map ori, is a problem of the map! But why not post it? You do not want to show other people your 'secrets'? Quiet, why not unveil any secret

    Hello, can I post calmly, on the contrary a another discussion about valves swirl I've already posted, but at the moment my map is original, only with egr off, and then has an area at the end that is different from the ori, but I don't understand what it was (checksum, of course, those are just a few bits).

    To me at the moment no error, only that the car is less responsive at low revs, and then give a strong push among the 2800/3000 rpm, you hear a lot in 2* and 3* gear.
    Given this jerk I think of all, the turbine has been rebuilt recently, and we had to make a half turn of the screw in the dipstick otherwise you really shooting me, I've been dreaming about!
    Go to understand if this difference is really the fault of the swirl missing.

    I figured it out. Perhaps before changing the turbine was too reactive, because the geometry is not opened the whole. Now, however, it seems that the geometry fails to close.

    No prior to repair of the turbine the car up to the 3000giri was dead, then suddenly 3000giri started to rocket!
    In the past, before the whole story of the game was a missile since the low reggimi.
    Now with the turbine regenerated it's much better to be low compared to periods before you re-key it, but these steps, if I accelerate gradually the shot, does so at 2800/3000 rpm, but if thrust the pedal 3* for example, triggered by 1800 rpm, up to that regime rises a little more slowly.

    Hi guys, I'm new here, I wanted to ask you another thing (I motato now that starts to get hot and travel with the windows open), the turbine whistles for a quite a while, it's nice sound and I agree, but I don't know if I should worry about because he has been regenerated just 10000km ago', what do you think? As you hear the whistling of your turbine

    hello, but still spins with the vts adjusted by your mechanic? I would not like having a setting wrong in the long run it greets the turbo (assumption mine), anyway mine also feels a little a bit, and the sound of a prex and a little because I kat and fap. The whistle accented and symptom of balancing wrong.

    but instead of 1000 guesses to make a log with pressure objective/measured and % closure geometry is too difficult?

    How to adjust unfortunately, I only have half a turn of the screw in more, if left as it is returned from the review, the car was very slow to climb rpm.
    Of tracks with the MES I've made several, but unfortunately I do not know how to interpret them to the maximum, what is known is a trend that is strange (in the sense that with the throttle at about half, the pressure shoots up to peak 1,6/1,8 "would be the 2.6/2.8 mes", and then decline after 2800 rpm, and just in that moment that you feel an extra boost from the engine), now I can also make new, or to see what values I put in those facts.
    As you are interested in? Doing some testing and sinking of the pedal? Or accelerator
    Constant?
    However, I do not know what is the value of the geometry, now I do not remember him, in those that I have done I have placed sure accelerator, press. Measured, press. Objective, and the number of laps.

    Valve I remember the value valve parzializzateice flow, (if I'm not mistaken are the swirl), what is the value of the geometry that escapes me? Maybe I can saw and I don't remember.

    forgive me but apart from the whistle of the turbo the car should not be?
