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..
Have you compared the maps? it is not me the times are different.. they are adapted to work with pressures pi? high:Originally Written by Danny

The patience and virtue of the strong..
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.
Comparison tinj 75-90.jpg
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.

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)
Why? from the original I have these values, the table should be right cos?
table tinj(prail,qmain).jpg
As you can see the last column corresponds to the pressure of 1700 bar, and for this we do not have the time of injection...
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.
