Then changed the bit 06748E (I have a point, but the file has the same addresses of the one posted here.. at least for the rail), and now finally from the time of diagnosis in pressure lens, I have the value which I set in the map of the rail.
Made a map from 1600 bar... but the machine should not be linear, and the light injection. Peak has given me 1509 bar but the pressure drops and spikes, even if pressure goal ? always up to 1600 bar...
Made the map 1550 bar I as a target of 1550, and rightly, but the machine is as with the first test... pressure dancer... max 1484 bar...

The error is always the same P1196 temporary error, fuel pressure

That really has problems with the filter?
Let's say that even with the map at 1480 bar as I had before and without the change bit for me was that sometimes it gave the error but did it when I pulled over the 4500 rpm... that is creating really a depression because it requires more? oil as it comes?
Has anyone had any of these problems?

Hi faith, you wrote changed the bit 06748E...if I understood well by raising the bit you go to raise the limiter of the rail pressure?

[ake85]

According to me c'? some other bit or I can not understand the map well 67A06... limiter rail in function of the temp of the diesel... " for an axis, I the temperature of the diesel but in the other should be the rpm... but I don't understand the conversion factor, and if they really are spins or no...
I say cos? why? even with no change in these 4-bit single you talked about here in the discussion when trying to go on with the rail I had the error also making maps from 1450 bar while if I remember correctly, some time ago I tried a map from 1480 bar and that gave me error... now I can't find it on the pi?.. are in pi? 110 the scriptures....

The alternative would be to change the bits of the gain of the sensor rail... knowing what ?... cos? to do ir? or less what makes a form. Of course, in the diagnosis do I have to do a map type to 1400 bar which is actually? then they will be more? as the sensor reads less than the actual pressure and therefore the pump pushes the pi?... drawback then ? as an analog module with the linear trend, and then I would have pi? pressure always...

For now I put a map at 1430, and goes to that ? a show and, above all, no lights. That of 1600 bar was one of my obsession to replace the injectors, 1.3 95 hp and get them to work precisely to 1600 bar ? the pressure of work.

for me, the best solution would be to buy a machine that delivers 140 horsepower and you will see that there will be no more problems...anyway, I'm reading around the topic and I admire you for all of the tests that you did really good

[ake85]

I think that sometimes you have to also know if the mechanical components such as the rail so the pump,injectors,fuel injectors,sensor flute rail pressure, are perfectly intact, without any problem, why? just one of these mechanical organs do not work properly, here is the explanation of the problem of recovery.That's why? c'? people who do not have problems with errors caused by the pressure even if modifcano the two bits, bringing the pressure even at 1600 mbar.

once you combine the maximum amount of points if you increase the pressure, I by mistake I remove the increase gives me more error then:
problem pump
the pump fails to go beyond that limit
the sensor does not ? calibrated for that type of pressure
result:
best to change the pump, buy a car with so many horses in the most...

You, ? a limiter is a single bit. The problem for? as I understand it is in the pressure regulator mounted on the rail. I recovered the flute, and a pressure regulator of a Grande Punto 90 and with this it should disappear the problem of the pressure on the dancer.
Do I have to? still have to mount the whole perch? I don't have much time.
I would also have a BV35 to assemble and I would also have a exhaust manifold from the flange with a GTB1549V derivation 2.0 Mjt 170 hp, which still seems a bit extreme as what to do.

[Danny]

On 69 hp, the p-rail ? clear offset to -100, so no conversion...
Instead, as regards the limitation, is always up to 1460, and to go further ? always a discourse of bit of limitation...I have to test on 69 if it works, as soon as I can.

[Ela.Toretto]

Danny but on 75 you did?

[Exelion1986]

I was searching the internet looking for all the info as possible on this ecu and I came across an interesting document
place a screen of that document ? given a map, which according to them would be that of the preiniezioni
in the reference file of the first post is located at the address 0695A0 and corresponds to the point table to point to? I have no idea of the conversion factors
someone knows something more??

We have temperature and numbers of laps and the z axis the amount? of diesel in the entry then this map tells you that at 800 rpm with a temperature of -20 - 10 ?C is entradno 10 mm3/stroke...I know why it is mapping varies MJD8F
