How to recognize the maps of ecm titanium

And, as the BP of the map lambda of this delta, we arrive at 1000 mg/hub to 68mg of inj (80 mm3) of the BP does not need to change it.

multiply cc x bars where did you get it? sure that is right? seems a little too simple....

You are sure of this. In a cylinder with a volume of 400cc can contain a maximum of 400cc of air at atmospheric pressure if doubling the pressure will contain a double volume. So if in the space of 400cc of volume, I put the 800cc of air will have a pressure of 2 bar or 2 times that of the atmosphere, if I put a 1000cc in the same volume have a pressure of 2.5 bar, and so on.

You are going in a loop with the calculations even if you need to understand them thoroughly.
The next step I would say to go to the definition of the map view bp at least for us without winols start the challenge...
Especially the nm and degrees should be defined that I have not understood it..

Begins to look at maps lambda as we have already said. Look at the axes of the Bp on the first (Y) have the value of the RPM on the second (X) you have the mg/hub that reads the maf. On the curves (Z-axis) you have the values, with conversion to 0.001. I know that the value 1 on this axis, you limit the Iq to the ideal value of Afr. In this case, holding a 1 in the lower right of the table we should be able to inject all of the 68mg inj (80mm3). So let's try, let's begin to moddare, put a 1 ( or 1000 depending on the driver ) in the table from the middle of the y-axis and the middle axis x in the then and email the file. Then we go on with the other maps to inform the ecu that we want to inject 80 mm3

I am preparing the file, I do this change to all the maps the lambda?or all 4?

Delta mod lambda.rar here's the files with the different maps lambda brought to the 1000 from the mid-axis then

errecinque not to contraddirti but to understand more,I am hooked to the speech and as far as the 7000 on the bp, according to me, are not always and only iq,if you go for example to look at the map rail pressure you can also see them in the bp to 7000 but in this case we talk about pressure diesel is not the amount that you entered...that's why I was wondering how do you define that the map we are next without a driver... it gives a look at the address 1FB83A and check the bp of this map

Almost all edc16 fiat have the maps already calculated for 70mm3. The map rail pressure indicates the pressure to give in tot laps tot iq. I the driver that you indicated that the ecm gives it to me in red, and then taking another I have seen that does not convert exactly the iq, but gives you the usual percentage of load.....I don't know if what you use is more accurate

[giuseppe89]

I'm using this driver because my file is identical to another on the forum, and the ecm uses this driver for this second file,being equal I think the driver goes well for this...beyond all I did some tests to raise the rail pressure and then works at least on this we....maybe we should do other tests to see if the driver is correct all around.With regard to the values that the ecm gives us the maps diesel should be expressed in newton and then you have to convert them in mm3,wandering in search of info, I've read some post in which you spoke of a 500 nw = 100 mm3 . The report then 5=1 someone confirm if this correct?

According to me it is not correct. Among the maps contained in the ecu there is one that converts the torque request in the amount of fuel to be injected.
Let's say that they are driving a vehicle, you press on the gas pedal for about 20% of its stroke, and are at 1500 rpm. The first map that works is the one called Driver Wish, or map the pedal or a similar name, so to speak, combining the data pressure on the pedal 20% (on the map you will find 0,2*8192=1638) on the column, and 1500 rpm I will have a value of, for example 1221, which should be divided by 10, and then 122,1. This is the torque request. We skip the step of the control in detailed relief of a couple and we arrive to the map converting torque diesel. On one axis, I will find still the rpm, then 1500, on the other, I will find the values of the required torque which, for example, are 1000 and 1250 (as in our example, we requested 1221) so I'll have to interpolate the data to obtain the value of fuel to be injected.

....... 1000 1250

1500 1750 2250

then by interpolation, I get the 2192, then the quantity of diesel to be injected to fulfill the requirement of the pedal 21,92mm3.

All this to say that there is a table already calculated by the manufacturer with the calculations made to know how much diesel it takes to get a certain pair, also because it is the variable this amount depending on rpm's.
For example, the map I have an eye on myself (not being able to download others) has a column like this

....... 4000
1500 9760
1750 8890
2000 8390
2250 8315

so as you can see 83,15mm3 of fuel generates 400Nm of torque at 2250 but to have the same torque at 1500 rpm I need to 97,60, then multiplied by 5 according to me it has no sense

comunqueper completeness of the info in the map nm on iq,then that is the map "command iq vs time of injectors opening" always take into consideration the maximum iq relative to the maximum torque calculated in the positive...that is your iq on nm optimum calculated from the mother house
