Boys but now we are going to a p? off topic... :/
I apologize...
Returning in topic, the torque limiter as a function of the coolant temperature reads to the contrary? Why? reading it from right to left ? very similar to the affinity of the driver's wish.
the bit that limit the pressure turbo 2, are in the clear with a decimal value of 1500barQuote:

search the esa strings 0014 004b 05dc change bit 05dc
search the esa strings 1388 000f 05dc change bit 05dc
Sorry for the trivial question, but how we look for the strings? c'? some method?Quote:

I had only changed the bit to 06112A and I had no ir? the cut at 1.5 bar... c'? to say that I have not pushed over 1.55 bar having the kp35Quote:

It's still a bit to 1500 and is located at the address 06112A (In my point 1065P351 but also in the files of the lancia Y 70 hp posted here at the beginning)
The bit that limit the turbo pressure are two of them, in the file posted here on the forum ( lancia y) correspond, tried the other two files, point 75 and the point 70, the pressure of 1500mb exceeded.. you are close to a bit which limit the engine rpm..Quote:

But in the gp 75hp have the same values of these posted here? anyway, a thousand thanks riccardo92 ;)
But the fact that by changing the bit to 06112A gi? I cut more?... you know what match I'm bit that I edited?Quote:

Let's examine the map main injection as it is called in the ECM, it is a map, 16 x 24 ( 16 columns and 24-line) visible to 16bit, many argue that it is a map inverted, others not.. but the concept of the interpretation of the map and all wrong, in fact, not the year of the rpm x load, etc.. but bens? on the X-axis we have the Rail pressure while on the Y-axis the amount? injected IQ measured in mm3/str (mm3/stroke)
the name of the map ?: SR - Main inj. ctrl - Injector map for small Qmain: f(Prail,Qmain)
value X = (2 x Eprom) -100 offset - pressure
value Y = (0,002930 x eprom) - IQ
For? I cut more?.. from the diagnosis, I read over 1.5 bar without going into recovery as before.Quote:

With respect to the rail... I looked in the MJD8 there are two entries...
"On threshold to recognize overpressure event " value 1750 (eprom*2-100)
"Off threshold to recognize overpressure event" value 1680 (eprom*2-100)
These should be in the MJD6 with values maybe more? low...
Do you think this may be caused by these instabilities? if you climb over 1480bar or and the light of recovery, even with the mod that you suggested (the two bits that only 1450bar)
The warm-up map should be used only in the phase of heating of the engine... at least going behind the name of the map
the damos, however, should say if ? positive, negative, or no...
from the shape of the map according to me...the last curve on the right,the most high of all,it corresponds to the injection time for the bottom press rail and the lower amount? injected....in fact, the time of injection ? very long..***** and in a normal map Tinj where in fact the curve is trovva at the beginning of all the others looking at the map always in 2d..
Another map to consider this when changing the Rail pressure and the map:
SR - Main inj. ctrl - Minimum main quantity: f(Prail) map 16 x 1 where there are 16 columns and 1 row
this is a map where it is defined as a constant minimum injection equal to the value of the map multiplied by the value of the conversion..
in our file review of the map is the first map main injection has as a reference in the X-axis
value X pressure =( 2 x eprom ) -100 offset
y value IQ = constant
y and given by the ratio between the eprom x 0,002930
note that the constant injection on the map comes up to the limit rail pressure after, and zero
so it makes it appropriate after the edit limit rail pressure, lengthen the time constant after the pressure limit of the source as you can? note from the annex ? zero
From what I think I any curve ? a value of IQ, and the last curve on the right ? the curve with the highest IQ then any curve going from left to right each value ? of a particular the rail pressure that gradually increases...Quote:

Perfect, have to be modified times on the maps over the limit Rail pressure.. I give it for granted mentioned earlier on the backQuote:

I also tried to do the mod to the two bits of the limiter turbo that you said but it goes into recovery and error boost pressure.
The same file with these two bits of gold, but with the bit that you said I the machine should not be in recovery.
Hello Faith I ? strange your situation, limiters press turbo are the ones I tested them as a gi? said about point 75 and 70, for the diesel I would be curious to know what you edit.. post the mod files and ori..
If you do not ? a problem you send it on Skype... I sent you a message with the request.Quote:

But why? not ? linear? If you double the pressure half the time of opening. It is because of the opening times of the injectors?
I don ? got nothing.. try againQuote:

Great guys! But from the original, really inietterebbe 65mm3?
From what I see in the diagnosis injects a lot less... I seem to have seen values around 46/48 mm3
Umh, would be to understand the xk? behaves so?, and not inject gi? that quantity? of Diesel fuel.
Surely many limiters restrict this value... then c'? also a map that should restrict the mm3 as a function of the engine rpm.Quote:

The map in question (the map 4x1 065574 in our files from 70cv)should limit the following values:
what is the meaning of a request like that? it's not even worth to continue the discussion without seeing the file.Quote:

-2-bit and limited to 1450 bar----- 605BA and 6748E
-limiter rail in the function p boost --- 674BE
-map rail (up to 1600 bar----- 675BE
-lim rail as a function of the temp of the fuel----- 67A06
-Minimum main quantity f(Prail)---- 689D6
-injection times with times of up to 1700 bar rail---- 68A46
Here's the files that I have not tested yet. Do you say that ? made according to the directions of backgroop?
Umh, But you should only do the brack point to be able to take advantage of the 1600bar pressure? Or better, if everything remains the same, however, it should ricalcolarsi all the ecu, I don't think that should stop interacting from 1400 to 1600 bar...
also I find an irregular course from the 3000 and 3300 rpm, the car goes jerky... for me? the break of the injection I have not changed, you say, is that the problem?
Personally I don't think the servant to do the injection in that way, since? the gp90 has the same t in the 75, but at pressures pi? high..
:confused:
I have trawled the two files of a gp 75 and 90 for the speech of the rail, and I remember they were the same in the t' inj.
Maybe for? you have compared the 69 with the 90, and may also be different, even the injectors are different....Please, forgive me.
Here, this ? the comparison between 75/90.
I apologize for the error pocansi. Having said this, we deduce that on the 75 the tinj may remain the same, even managing to raise the pressure. :cool:
Then according to you ? better to modify the breakpoint (value of 1500 to carry it to 1600), or as I have done to stretch all the curves a bit to have a value of time of injection to 1700 bar?
Wanting with the my solution and I could also change the break and set to 1600 instead of 1700 to have a curve ir? linear
Here I do not know, in theory it's the brack point, but you would have everything scaled differently...as in the point where now ? at 200 bar, then sar? 230(I suppose numbers to the case)
Reading this post, I'm learning a lot of things, so first of all thanks to all of you, I have a panda 70cv, the addresses are different than the map in question, but substantially ? equal, just find the correspondence.
They are at the same point Fede78, I raised 2 limiters 830( 830x2-100 equal 1560) and modified the various addresses related to the pressure, but diagnosis of the pressure as soon as more than 1450 began to swing in the graph, the pressure peaks are up to 1560 bar.
The brack-point change, I believe, is to address 068A26, but are not yet able to understand it, the values start at 50 and go up to 900.
Now I try to stretch the curves of the main injection of a bit, and then let's see what it says in the diagnosis.
a greeting to all
Lengthening the curves, the pressure does not fluctuate more?, but not salt, from a peak of 1500 and then cala gradually bringing it to the original value, about 1350bar, instead of leaving the original two-bit 775, rises to 1450 and remains constant( but 4? gear up to 4500 rpm)
a greeting to all.
I tried the file with only the rail and related limiters changed with the times (stretched), but all of the torque limiters ori.
But always error fuel pressure and pressure that, however, doesn't it ? stable and in any case does not rise above the 1490/1500 bar.
From the tip of Backgroop I also modified the other two bits in my file of the point (but also that of the y as they are identical) to the addresses 655D4 and 655DB that there should be two other limiters of the rail pressure (eprom*2-100)
But even with these two bits, the situation does not change.
