View The Full Version : The times of injection Grande Punto 1.3 mjet 90 cv
Hi friends. . can you give me a hand to figure out how to change the timing of fuel injection, which ECM called "injection split" on this grande punto 90 hp ? I modified the pedal by removing the holes in the acceleration , but I noticed that if you do not touch the map of the times solve little on the low...I've done a bunch of tests but nothing. Attached file ori and confided in a your help...thanks to all !
the problem and more on the torque limiter, engine
the times I do them in both tabular with interpolation using the % for surface curves to lines
Limiters
1° 084934
2° 08DBA6
3° 08DBC6
4° 0903A0
5° 090412
6° 090458
7° 090632
8° 090EDE
9° 091D30
Ahhhahhhhh...nooooo...I'm with the phone... The place as soon as the load on the....are less-experienced on Marelli....industrial espionage deserves 100 thanks!!!
But the times, as the li calculations? Or from a % fixed?
from the 10% increase in then you start to see a bit of smoke
I ask this because in the ECM, the axes are wrong...it should be the X-axis rail pressure and the Y-axis injected quantity in Mg ...Z-axis the time in microseconds... am I Wrong?
Already thanks, but I tried to pick up and I hear a bit of mumbling strange to the engine and you feel how you feel a bo of the beat..

Then it varies from car to car..
The 90hp still giving the right amount of air it can give you up to 16% 100 load 4500giri
However, they are rail milliseconds mg..
Try to give
5%-8%
3%-14%
38 load 1000giri up
I will try and tell you..thanks
Hello Andrea, I also have a GP 1.3 jtdm 90hp and I have to say that this motor (1.3) has surprised me a lot...
With a few simple changes to ****llo suction delivery and' changed so much, he thinks that now ride again with the file golds except for closing the EGR (I have made this choice because I do on average 40/45000 Km this year and I have the clutch a bit tired).
Long ago I did a lot of tests and with regard to the timing of the injection I was fine with an increase in percentage from 5 to 10 but already with changes to the exhaust and other small tweaks in the map...
Do more tests to find the right combination that fits to your engine, your driving style and any changes you made, otherwise, go to diagnosis, to measure the amount of air you can suck in and do you calculate the right quantity to be injected...
A piece of advice... every time you write a new map, test it for a couple of weeks (depending on how much road walk normally) in a way that makes the necessary readjustments...
Cinqueturbo I'm sorry. As we pull on those limiters ? I tried but the car has a pedal empty, worse than the original..... Not to be damn...

See the classic panettone you read to the contrary.. where laws 700, in reality, and 4500

The limit of the ECU and 12800, to release the vacuum on different SW, I had to give it already to 900giri for example, 1000 points
I knew they were on the contrary.....also the pedal..... The rail I have raised 5℅ with its limiter...the turbo of 15 points ....but not to be

If not put the file I don't know what else to tell you...
I'm sorry. As soon as I'm home the place...
I made a mistake to plant the file ori....Alas, in the workshop I don't have a moment of respite... I apologize...and anyway thank you in advance for the help...
here are the files ori the most mod...thank you and don't hurt me!!!!
Cinqueturbo you say ? Is espionage??? Ahhhhahh
Then, the map and raw and I don't like the absence of logic, but not for this should have that void that you say you have..
tell me what you want to achieve and what makes the car...
for a start have you made of the log to monitor MAF, MAP, etc?
it's crucial that the MAF read at least 800mg of air..
The log I did.....with multi****can and everything is in the norm....But I did it from the original....then I did not understand the logic of these Marelli that you say xchè is all in newtonmetri and I don't have experience x in the various calculations, etc, etc...
I would just like to get good performance at low....xchè after the 2000 rpm the car goes....but below is ugly

Given that I have no experience in the matter, and then I might be wrong, in fact surely a mistake, but to pull out the horses under the 2000 rpm's is a thing a lot more difficult than not get them at a high rpm, however, the thing interests me greatly because I too would like to have a lot of cavalry at low rpm but I think with the turbo that works with pressures low enough below 2000 rpm you have little air available to burn the fuel so I don't think you will be able to increase in power
how many mm3 max can you inject?
Sorry for the intrusion, but anke and I have made a number of 1.3 mtj, and I noticed that the hole that has below 2000 rpm, and really difficult to remove it....

I repeat that you have forgotten 084BE6
Here we talk about a diesel that has torque amount
Not a problem to get it to push straight away but problems that involve..
Put too much copy on the bottom and without having knowledge of the logic leading to several problems.
This car has the flywheel, bi mass, and send him into retirement soon
It becomes a place inqueto.
Duco ask why, however, no mechanical changes will not come forth who knows how many Horses..
I tried to put the injection time ori.... I have hard that it is more linear, and that there isn't that hum....also in the maps on the pedal I have not touched any of the values in the negative...I've done it right?
that mumbling is when you increase a little more at low revs the tj.
Do not touch. It is used for the cutoff at the time of release.
