MARELLI MJET impariamola!

Someone could make a screen of advances with the direction of reading, so you can figure out how many laps one is

advance stroke c.jpg
this ? map advance of the opel corsa c the sense of reading ? as I drew the arrow.
each curve corresponds to a different iq of 65, 60, 55.... and represents the y-axis; taking into consideration a curve only to simplify and
scrolling with the mouse over to display rpm numbers (x-axis)

notice how it is different this map compared to that of the point with the same horses.
the map in question is prior to the injection zoned

c'? no one?

[mjet10]

You dariuccio thanks for the screen

hello to all
since I have a couple of friends that have the 1.3 70 hp, I also put myself to the study of this unit
first of all, I would like to make you my compliments for the nice discussion, I have learned so much
however, even after reading the whole 4 or 5 times, it still remains in some doubt, especially relating to the conversion factors
I have seen that ? been shown the most? times a factor of 0.5 for the temperatures but, comparing the screen that you have posted, I just can't let me go
referring, for example, the torque limiter as a function of the temperature of the water makes me think that there is an offset
in fact, not ? that is so influential to know exactly these values to change, but I would like to clarify a couple of things for a matter of completeness

[Fede78]

In the torque limiter as a function of the temperature of the water to the axis of the temperature has a factor of 0.5 and offset -100

[Exelion1986]

thanks ? as I suspected
another thing that I did not go back ? the conversion factor of the limiter rail pressure for water temperature
you have indicated eeprom*8-100 but cos? I are high values, almost 4000 bar, and then ? the normal range of the rpm go from 4167 to 18750?
however, turning on the net I found some other map that could be interesting
addresses 065AF0 and 065D30 of the file of the y reference there might be maps of smoke, with a conversion factor 0,001302
in some mod I've also seen ? changed the map corresponding to the address 068138, with the justification for that ? a torque limiter, and also that the 0628A4, but of this I have no information
there is something?

[Raffaele87]

good evening, raffaele and also I'm interested in this discussion... I would be interested to know how to raise and change the pressure limiters

[francescosparco]

hello I know someone indicate how to change the limiter in such a way as to shoot the car? and the same for the bosch??

[Exelion1986]

from what I understand it should be a bit just before the injection time (or as he calls them ecm injection zoned), with the value in the clear 6000
for? I have not tried if it works
