Turbo Alfa 159 150 HP vs 210CV

[msport (exil77grande)]

I had heard that it was not easy to manage the geometry on this turbine...if you are talking about so I think that a mod you have already made..... in egffetti I knew I had to play with the maps of the geometry.... thing that up until now I have never done.... I don't understand a thing.... x which is why it behaves like you said?? xk? climbs, then descends again then it goes back and then comes down again??? I could take reference from the maps of the geometry of a brera 210cv??

definitely closely studying the maps of the turbo 210cv something comes out.

I also thought I to what you said.... my idea was to copy the maps in the engine management from 210cv... then, surely, given that to me is missing a cylinder... the pressure theoretically ? more low.... at that point... start to raise slowly, by 5% on all the maps of the management turbo... and then I aiutero' with log based on rpm, pedal, prex, turbo, and proportion valve... for example.... if I see that absurd... 2800 rpm with a load of 80%, a percentage of valve 70% of the pressure spike, in an overboost to 2 bar, for example, wear' l' opening of the valve in the 60% to lower this phenomenon to that number of turns....
theoretically no if I remember correctly... the more the percentage ? high and the blades are closed... that is, in the charge phase, the more the blades are open (betting towards the impeller) then percentage type to 30% and more and be in a position of stable pressure, right??

I was joking indeed, I would like to thank you for all this info that we're giving... all these things, you know, to work or just for passion?

not ? cos? simple rules why? going to change the duty cycle of the valve n75 is v? to madden the PID control that ? a control system for the turbo pressure.....
you should change this to the pid control then go to the mod on the n75....
only that many preparers also known prefer not to touch the map pid to not mess up the life why? and really tough to fix...this control uses a logic of their own which is entirely different from the one pu? management "simplistic" of such as you have described you.....
when I replace the turbines with other more large and I prefer not to touch the maps in the ecu and the act on the adjustment screw of the actuator itself....I do first cos? through the map even if sprucing up on the map, sometimes I have to give...
for you to better understand the pid control I would like to post a link that explains pretty well what I'm talking about but it's not? if I can....

what you say you're right.... but what do you do you ****llo mechanical??? if I have a problem like you described.... original, pike high, corrects and lowers, then revenge, then corrects, and then lowers..... if this is the case.... and the fix only mechanically.... I would have a lag at low revs, then starts to climb... and pulls up top.... if instead, I go to tap the map of the turbo.... I don't know if you've noticed.... to the midrange on the management of 2400 falls again, the percentage of valve type at 60% instead of 70/75% in order to lower the pressure in those ****lli.... you say that logic is wrong??? these controls that you say.... how do you understand them and where are they located??
