Maps Lambda EDC16

[lsdlsd88]

if there is someone who chews the bread and Funktionsrahmen, I would explain why in EDC16 (I mean fiat/alfa etc), are values of lambda at high IQ who come to 1.1 (some even 1.03), which would mean then AFR of 15.5, while in the EDC15 on the smoke map were APPROXIMATELY around 70mm to 1000 mg of air, which if we convert in mg leaves approximately 17.5:1 as the AFR?

I from what I understand the values of the maps the lambda are calculated as the ratio of mg of air in mm of diesel fuel (wrongly) for this to come out AFR falsely low.
however, it seems to me an error so gross, do not consider the variation of density of diesel fuel compared to the temp folder, which I cannot explain.

has anyone ever put a nice wideband to see if they match?

ABOUT around 70mm to 1000 mg of air, which if we convert in mg leaves approximately 17.5:1 as the AFR?

EDIT: for the accuracy 70.47 on 1050 (I'm looking at a 147 1.9..)

if you see a file of a 159 2.4 values of gold under 0.8

Well, but not in the area of IQ maximum I hope? in some areas there is to take into account also the EGR I know...

1050 mg air - 3750 rpm

I believe that in order to do a work up once you have completed the map, and unlocks the lim iq to the desired value, you need to do the log with the map lambda all to 1 and correct then according to the values of the beds in the areas with too much or not enough iq

[lsdlsd88]

Mah, if the parts to be 0.8 it seems to me absurd to put it at 1. unless you discover that with the map lambda ori SMOKES (I doubt).

it is also true that the map ori probably has the IQ were limited by other parts and then maybe you do not often be limited by the lambda.

Beautiful strange, however, is what!

The main difference lies in the way of how to work with the ECU..
In edc15 all the calculation algorithm and as a function of the amount of diesel then the map smoke and seal in the primary consideration..
In edc16 the processor based all the calculations in a function of torque..
The maps lambda are simulated and taken into calculation by the processor for the most part for a matter relating to anti-pollution devices..
In fact, when you delete the maf on these the ecu the processor continues to work, based on other maps..

[lsdlsd88]

.... without the maf it will work in speed density I guess? but this was not my question XD

what I don't understand is why not "come back" the accounts between the air and the diesel, there are other parameters that the ecu applies to the values that is written in the maps lambda according to you?

[franco75]

for the stoichiometric ratio, you should use the weight of the air and the weight of the fuel, not the volume. To ****s chemistry is so then that calculations to do the ecu I don't know
