the logical proof, and the practice is to make a map with the lambda ori and a moddate and log the quantity of air vs Iq.
better post screen of the maps so we relate better, where to find l afr so low and make 2 logs on the road and see if they match.
you can request 500 nm of torque and then 100 mm3 of fuel (edc16c39 150hp) but you can get it with 1200 mg or 1400 mg of air always depends on the lambda.
x the conversation of the limiters that mean I can set up a afr of 14.5, but if you're struck by the surge does not reach a certain IQ, then that value in the map is a little ridiculous if you do not take action on the other.

What you say about lambda edc16, and this is just part of the amount of fuel injection of the final in these ecu and extrapolated crude from the map nm-iq, and subsequently "clean" from the map, lambda, and various limiters are scattered in the eprom after that, the ecu knows how long to hold open the injectors to inject X fuel

I try to have my say to see if I have understood the concept. Let's say that you want to have a torque of 400 Nm at 4000 rpm then the map nm-iq revenue the value 83,70 then for a given extrapolated in the rough you want to own this 83,70 mm3 of diesel oil, then clean from the map lambda I want to say that I must search in the map the lambda to the corresponding value for 4000 rpm crossed with the amount of air, because the table stops at 1050,0 and 3750 and it is likely that at 4000 rpm the air intake is already more than 1,05 gr, let's say for example 1,15, the value, however, is that given by that intersection is the last one available and then 1,13. Then I convert the 83,70 mm3 in weight by multiplying by 0,835, and then 69,8895 mg and comparing them with the available air. In the example, 1150 mg of air according to the map the lambda would be sufficient to 1150/(14,7*1,13)=69,23 mg of diesel, so I have to "clean" the 69,8895 and reduce it to 69,23 because the map lamdba me limited to that value.

I understand that you're a little too tied to the concept of a lambda of the gas that would translate on the diesel.. I hope you will understand a poor confused like me..but:
1) the diesel can work with afr Of 60:1 at the minimum in the maps lambda EDC16c39 you find this value?
2)if you apply a player stoichiometric on a diesel engine EDC16c39 or any other ecu you will notice that the value in the map lambda in the ECU and very far from the actual value read from the instrument because the said several times in several of my back
3)since you talk about the logic of the ecu and I am a little confused according to you, I would like to me the chiarissi this logic you have ever seen that learned something that I still don't understand.
4)with the emoticons is that soften the sense of the message and, anyway, if you want that there is more in your tread you'll settle quiet..

I know that we speak 2 different languages.

From a former student of Computer science and Engineering, to hear talk of "crude" and "clean" in a microprocessor makes me cringe.

the ecu works with logic, formulas and numbers, accurate at least up to the third decimal place XD

The options are 2, you'll forgive me the bluntness, but are done so:
1) you have the ideas a little confused
2) don't want to say too much because we are in the section of those who should not know anything.

prepondo for the second.
I wish so much that to intervene in someone else's right to give their opinion, not because I do not trust your answers, only that they seem to me, at least, vague.

Thanks again

Isdisd88 you're wrong and in a big way!I don't want to defend neither the forum nor the Munro but here, there is a "section" where you know/not to know things,everything is in the light of the forum.own Munro is not the type to be "vague"....... You explained it more than once,and I realized it too! And are not graduated... ..... .. ......

[franco75]

It seems to me that Munro is state of clear. For raw I think that Munro intended that the calculation of the IQ still is not complete if you do not first pass through other limiters.
Among these limitations is the minimum value of lambda is allowed. Past this you additional control and definitely the other, the calculation becomes "clean" and final.
Now if you want to force to interpret the evil,instead of to thank, the one that tells you a person like Munro who has always helped me a lot in this forum do as well.
I hope I helped you.

then decide how much diesel to inject is the map limiter smoke; hence the' so called from the ecm?

it is not only the lambda is the lambda

[Errecinque]

it is not only the lambda is the lambda

However, all of the maps in relief we still don't know who has the last word...that is what the ecu asks for last. If I did the test of putting all the lamda KP if these are the last to give its consent theoretically the machine should not go am I right?

someone has the damos for the 147 jtd 140 cv edc16c8?
I wanted to know if all' inside of the damos I find the value using the controller (0,8 xxx) to transform the mm2 of diesel fuel in mg.

then the formula mm2 oil*0,8 xxx= mg diesel.
