then...I'll explain one thing at a time..the maps lambda is nothing more than the afr...indicate the relationship "air", that is, the air-fuel...it's just that the multiplication factor ? 0.001...example, if you find 1,38 means that you'll have a relationship stechio limited to 13.8....so, if you want to go down with the stechio and increase in the diesel fuel injected you have to DECREASE the lambda maps....for example, if you are able to team a 0.500, practically give the ecu to inject for a afr of 5...
for the advances in the speech ? right...considers that it would be good to stay within the 7 degrees of post inj, but within the 10 ? acceptable...

thank you so much for the explanation of the advance, now is actually the formula for the calculation anticpi ? simplified for should I tenerc onto that I should look at the distance the piston to tdc, then the theorem of pythagoras dynamic for every single degree of the movement of the tree by calculating the length viella and the cylinder from attack Rod/cylinder, since the speed of the shaft ? uniform but that of the piston no, you have to slow down to the extreme, however given that it slows down in equal momo in the pms and smes the formula for the calculation of the length of injection should be more or less correct, now the question ? ok to the maximum value of the post pms, but how many degrees I can anticipate prior to tdc, you can get to 30?? because if we take account of 4500 rpm with injection 70 mm3 I 22?, then I have about 900us injection (about as ? in the break point), which is equal to 24? then with time, the angular injection after tdc of 2 degrees, if 20% increase in avro 1080 us which is equivalent to 29? with time, the angular injection after tdc of 4?, this means that with this increase could leave the advance in gold, or even could decrease and take the time to post pms to 7?, but inn this case guadagnerei in terms of yield? or I could increase the duration of the injections up to 7?, but not ? too much? here is what I would like to understand just how to push me and if it is also lower down payments or increase the injection up to the maximum limit of advance from 7 to 10 ? the post pms

wrong. the value of 1000 corresponds to the stoichiometric ratio, then 14.7/1

I did a study on the advances that has me a little upset, then I butatto jun ua table exel converting the advances degrees in ms for injection of 70mm3 about 4500 rpm, the results are these on the attachment, because if I use 800 ms before to inject 70mm3 to 4500 rpm I need 1000 advance to inject them at 1000 rpm? at 1000 rpm, there are 700 bar, to inject 70mm3 to 700 bar we want (by making an account on the average value given that not c'? the grid on the timing of 70mm3) 2400us that about 1000 rpm, 14?, in this case, advance 6 ? I have 8 degrees post pms, here it would be useful to bring the value of post pms to 7 degrees so I could anticipate a degree, maybe 2 too many, I think that is the reasoning correct, the ecu 70mm3 since there are no break points is an average value, or the law of the bp of the 80mm3? this ? a key piece of information to calculate the tem0pi, I remember as soon as I started I put values in percentage to the event and many said to me that the maps were connected between them, didn't understand it at the time, now that I understand it

I read them from the driver 1.x, therefore, not in the absolute values to 2d, and then 1000 corresponds to the stechio, but in absolute values, I have already convert on ecm titanium for those maps

the ecu interpolates using the values of pi? cells.
Anyway, at low speeds not ? a problem to have post-injections, on the contrary, are advantageous because? send in the spool before the turbine. Then how can you have 70mm^3 to 1000 rpm... I think if we lose the first consequence would be the clutch that comes from the engine, like a freesbee

[tidus1985]

obvious that they can inject your comparison with the freesbee ? been nothing short of hilarious I'm still laughing anyway , interpolate and then interrogs more cells ? by drawing a line that takes the value that it reads that line ? an operation that has in logic you the same no? type, average values for more or more cells to find the missing value

[tidus1985]

I attach the converter from degrees to seconds in the base of the laps that I did with exel

[tidus1985]

at low injections in the order of 20mm3 I advances more of the duration of the injections, incredible, I'm changing to go at least 2-3 degrees after tdc, ? right advance at 4500 rpm to 17.5 mm3 that ? to 21? and the injection lasts 15.5?, set to advance to 14?, should be correct no? or they do so to slow down the turbine at high rpm?

[SandroMarciano]

The advances are selected based on the pi? factors, therefore I were you, I would leave them original, at the time I tried to edit them, but I had performance deteriorated and consumption as well...
Change only those to the maximum, where we actually intervene to ****s duration.
