hello.....
I understand.....yesterday was regenerating!!!!!
today I went to re-check the parameters of the dpf, and yesterday carried out a regeneration while I was doing the logs,for some reason the ecu has me excited for the egr, and probably limited the iq.
I redid the log and are just above the 70mg.
I enclose a....

p.s, with your question what I should come in mind....that was the iq max and his factor to the original the result 259 is the value I (b), that being 8-bit is 259 but the ecu calculates 255 then the max.

you should come into the mind, that even with iq below 70 the result is greater than 255, then in diagnosis, see 70

I don't follow, forgive me..........

Sleep on

but it also speaks to factor the original or the mod.
factor ori 0,037 if I injection 70, the ecu is 70*0,037 and is 259 being a map to 8-bit the max value gets to 255, so even if an injection-more than 70 he gives me back always the maximum value which is 255.

factor mod 0,0255 if I injection 70, the ecu is 70*0.0255 is 178, which is not my max, then my reading in diagnosis is correct up to the time when my ecu with the operation does not reach to its max value;in the case of the factor 0,0255 are 100mg.100*0.0255= 255.

now to your claim I don't understand if we have done a good job in changing the diagnosis or not.....
that is now the reading is correct and we have only increased the range of work.......????

[lsdlsd88]

factor ori 0,037 if I injection 70, the ecu is 70*0,037 and is 259 being a map to 8-bit the max value gets to 255, so even if an injection-more than 70 he gives me back always the maximum value which is 255.

and if you are 69mg, what do you see in the diagnosis (ori)?

[joker01]

always 70, because the ecu with the operation comes to 255,3...
if, however, there are 68 see 68 because it is 251,6

[lsdlsd88]

perfect I just wanted to let you know how ori is not very precise, if you saw 70 in the log could also be 69

in general, differences of 1-2mg are negligible imho.

[joker01]

Haha....you made me immediately think that I had not understood anything.......screen.....
That's why from the last log with iq ori saw several times 70;the ecu arrotondava.......
Then, when a point of the situation:
-we brought the reading of the diagnosis for the iq up to 100mg, and now we are accurate
-from log2 are arrived to the max to 71mg with 1200 mg air about then 16.9 afr,I could go down a little bit........
-from log1 during regeneration the egr seemed to be active(mg/air down in the diagnosis with the engine at the min rpm but the duty cycle latch even if 1% more);in theory, I have lowered the 2nd panettone for the regeneration....

[joker01]

I'm studying how to do small increments...let's say that I want to inject a little more diesel 75mg
-I've increased the last 2 bp of the maps nm to iq
-I lowered the last 2 bp of the lambda 4 0.5 so that I don't restrict all that much
now I was looking at the map the turbo to make calculations and rescaling the image up to 75mg now it stops at 65.

example 1750 rpm 620 nm wonder 74,6 mg in the turbo I see 1613.
to find out how much air do I have to use this formula:
cubic capacity/cylinder*1,2(density of air)*0,8=474,72
474,72*1613=765mg of air in my cylinder
here I am......
because if I do 765/65 me a afr of 11.7
