I don't know if the cock of the law! not in the list!
Here I am back here after a bit of time... if I wanted to increase the flow of fuel without lengthen the time of injection the only way ? to raise the pressure in the rail?
I ask why? by comparing the file ori of different power, I have the same times but with a different pressure of the rail
even if you raise the rail pressure, the ecu map and the time it will choose a bp with a pressure lower to give you the same diesel that you are limited by other maps...
A rider does not create queues even in the car...
a automoblista create queues even on a motorcycle...
But if you increase the flow rate, for example, from 130 to 135 mg and adjusting the various limiters in the ecu knows that he has to inject a quantity? greater than diesel right.
Assuming you want to leave unchanged the map of time (1C6552)? as a function of IQ and the rail pressure if to inject the new deal? of diesel the original times don't last enough I should then increase the pressure of the rail right?
What then?
From the diagnosis, I see that these values of the rail pressure are in PSI and not bar and turning up in the bar I get that I have the rail pressure of about 1100 bar... that I seem to be few... But other tractors of this series with less power have pressure even more? low and times are the same
I don't understand what you mean...you now you are limited to 70mm3 of diesel....
your map times and has been calculated from the mom bosch 1700 bar of rail and 90mm3 if I'm not mistaken...
if you do not adapt your limiters and maps rail does not inject the above...
if you increase only the press of the rail and its limiters adjusting all other limiters the ecu won't be never to choose the bp 1600 bar and 800us for example, to give you 70mm3 but it will choose the break point of 1100 bar and 980us....
and anyway 130-135mg in reality are 152-158mm3 of diesel....if now with 70mm3 you 225cv with 158mm3 you shall have as a minimum the double...
remember that we are talking about a edc16c39 precisely where the c stands for common rail, and in these ecu the iq should be read senmpre in mm3, even if the diagnosis or the scanner give us the iq in mg....

The map of the limitation of IQ as a function of the rpm 1D428C has a conversion factor of 0.02 and, therefore, should be limited to 123 mg.
The map of time 1C6552 ? climbing up to 180 mm3 (factor of 0.02) and 1700 bar.
This hex and a2l...
The fact remains that the pressure of the rail from the diagnosis to me to be in psi and turning it into bars correspond to about 1100 bar
make a p? as much as you can....

For? having two ****lli power cio? 225cv, and mode? boost (transport above 18 km/h, with the pto under load) 251cv I have to have two maps, no?
Since the map of the times ? gi? climbing to the IQ up to 180 mm3 and up to 1700 bar I don't think the servant to change it because if you increase the various limiters of IQ and the torque limiter when the avr? a request for a diesel that is higher than the current ecu I andr? to choose the time of injection based on the new IQ and the pressure of the rail right?
Torque limiters that are the limit in the error conditions of the engine I can also do not touch, right? The Cio? if it goes into recovery for some reason ? pi? right that is on the values that are set by the manufacturer?
I tried to make two maps, and I have written, the first about 10 days ago, the second a couple of days ago but I have not yet had the opportunity to test it in full.
I would have a few questions:
1. The rail pressure 1F205A, pi? the trend... what? I have that 1400/1500/1600 rpm the pressure ? pi? low schemes lower, then higher revs then the pressure increases. Looking at the map of another tractor pi? recently (with urea but the same engine Iveco NEF N67 ENT), as well as having the pressure to 1600 bar has a trend of linear pressure increase with rpm and iq
2. The curves 1D0B6E, 1D0BC0, 1D0C12, 1D0C64 I did not touch because from what I understand from damos are torque limiters in various cases of motor error. I have done well? In the mode? of the correct functioning should not be affected. While 1D390A Torque speed curves ? the torque limiter that I modified.
3. Map Lambda 1D665C I don't know if I've changed ... well.
I attach the file cos? if someone wants to give a look and an opinion.
Thanks.
