change advances

[pasquale]

Gi?, if we talk about together, then you have reason to 100%. Definitely not durer? 400k km, but if you think that maybe in 2 years it will have? remove it why? euro3 then you say....but you! My car has 95k miles thought as I rode!!

Hi to all, I would like to reopen this discussion because, in addition to being interesting and vital to the understanding of the mod to make advances, even the idea of what is going to be changed and the conditions under which it is clarified by reading the various rear
Now let us turn to the questions that I would like to ask...
Let's take an example on the car stock with engine 1,9 jtdm (in my case, the 147 120 hp-treated by the English name..) that as factors of advances ORI has:
975 (µsec has 22 degrees to 70mm3 of inj with 1600bar of prx at 4500rpm and calculated from the pms to 26,32 degrees (+ 5 degrees of post and I think there are too many).
In the incrementing of that map (we are talking about edc16c39) to take it to an iq equal to 100mm3, I calculate the times and all the rest that I need and finqui ok.
The last step before upload it is to climb the advances for the new IQ, which, from 22,01 degrees ori doing the calculations, I get to 1180 µsec with 31,86 degrees with the rail pressure to 1700 (having the pump rail of the lybra 2,4 I presume contains such a request without problems as it is not for a long time, of course..).
Now my question is this..
How do I determine the value to be set on the advances to ensure that you do not go out out with degrees (in theory as I understand it no more than 3, but they are voices) to be able to increase this map based on the increase of IQ ?
Just wondering what criteria should be increased (regardless of whether in % or calculated.. I have taste), and what are the limits to which I can escape?
I am working on this map but I'm stuck on these points, as the details are not clear enough about it.
I thought of climbing all the map advances so as to arrive at the maximum at 25 degrees that I know more than I'm going to the wall increases (not done, but read by tidus) but I don't know what criteria, if climbing by the 70mm3 to 100 with only 3 degrees at full load or, 60mm3 to 70mm3 are specular values, consider the step 24 as the value to be set in the table 80mm3 and keep it constant up to 100mm3, but does not make much sense...
I look forward to your opinions.
I'm attaching a screen of the table in excel on which I'm working on.. is a bit confusionata but I have locked up all the factors to which to refer for the calculations without the need to click elsewhere to search for values.
Enlighten me thanks
I have also read on post9 of this topic but I did not understand very well...

Hello, I answer you briefly what I think..
Let's say that each of us has different thoughts, I personally prefer to give a little more advance than finishing the injection and up to 10 degrees after tdc.. the failure of the engines, according to me, are more related to the map in general, and especially to the state of the components (especially the fuel injectors)..
Personally I also use 27.5-28 degrees on 8v and 30 degrees on the 16v. Certainly it's all about what to look for one from the machine, the turbine mounts, how to use the machine..
I have friends who have broken 8v with 25 degrees maximum advance as some that I do run with 27-28 degrees without problems, one also is very close to the 300cv so you can imagine the amount of fuel and turbo pressure that uses that engine (of course with the injectors appropriate).
According to me, I would never have an answer on how to do it because everyone has their own theories and opinions on the topic

Well, of course I was focused on hearing the personal opinions and have feedback/comparison with the most competent people in this regard.
Thank you for having shared your opinion and I hope they do also the other to get an idea of the most comprehensive on these advances

[tidus1985]

The speech of the advances is not a simple matter of quick response, to be sure should be tested in conjunction with a pressure probe in the room and the temperature in the room, but on average it seems that on the mjet 8v up to 25 degrees does not give problems, but I repeat, it seems, is not an exact science without the proper tools. With regard to the injections you are wrong, 5 degrees post tdc nn are too many, too many are 12/13, 5 degrees at 4500 are a luxury, in the mid range, you can stay up to 8/9 degrees post tdc for noj to have too much heat, and smoke; hence, anxhe because it helps and not a little to spool the turbo.

Haven says jack, noj and an exact science, and he tests it has made a lot more of me!

I agree that it is not an easy thing, it's a year almost that I have been in the way of the ecu (they are not of the craft in the slightest) and so the study advances the chaos in comparison to the rest.
What you say to probe the combustion ****th e amateur is impossible/time consuming, then for the purposes of the study is not a viable solution then less data to be faith
Honestly, I was hoping for your intervention, so much because I studied a lot with your post (thanks for sharing), so why are we talking about the same car you know like the palm of your hand.
Coming back to degrees then according to you the table that I posted I can safely stay to those values calculated ?
That is, from 22gradi ori to 70mm3 I can safely set the 31gradi to 100mm3 without too many problems?
I speak of course of advice for experience and not of calculation based on nothing as you said before.. only opinionismo

I have no doubt.. I have read many of your post and I have an idea of your preparation

You know that if you slap on a pylon of reinforced concrete, the tear down? T have written in clear letters 25 degrees max (28 for maps on an engine mod) , you can go to post up to 10. If you are in need of 31 degrees to 100 mm3, put 25 in the map and you will have 6 degrees of inj after tdc. It is clear stu fattu? Don't worry about the tones I and he we are used to

If I slam against a pillar, you move before him to me, and anyway if you do not slam your head I enjoy only half.. you know!
perfect.. all clear! Thank you to all 3 for the clarification
R5 uu fatt is chiar mo!
