The influence of the air mass meter
As the title suggests, I would like to study the influence of the air mass meter (or mass air flow sensor or flow meter) in the operation of the ECU.
In particular, I would like to clarify if is only used to optimize the combustion and prevent excessive pollution, exclusively through the limiter fumosit?, or if it is used from other maps, or for other purposes.
Thanks to anyone who will take it? participate in the discussion!
I don't know, but I think that has to intervene to adjust the fuel mixture to the "better". Then by analyzing the values from the first probe after the discharge, try to "optimize" the supply of diesel in relation to the quantity? and the temp of the air.
We look forward to the most? experts?!
On this there is no doubt!Originally Written by Danny
I know that it can catch the signals of the inlet air temperature and quantity? air flow sucked!
With regard to the temperature signal, is used in the various plans corettivi, so here we are.
But instead, as regards the signal of the quantity? the intake air? Is used exclusively for the map of the limiter in the flue gas, or is also used by other maps...
I think that only serves their pockets and why? every tot of
time breaks down and who wins are the manufacturers,according to me
they could very well do without it surely would have
found the solution, as for example the BMW m3 from 343cv
equipped with maf and the same version of the BMW m3 csl by 360cv
without

You've got the right in the sign!
Having a system that is not the best and not having the desire to throw money to replace it, I was trying to work around the problem...
For this I wanted to understand what maps are referenced to the signal sent from the mass air flow sensor...
You can go to fixed values, but I don't think that you can match
the work that makes the Maf,of course, I speak of us mere mortals
manufacturers can, however,

He says the same word air mass meter and the cio? serves
to make it clear to the ECU how much air is being removed, and therefore
adjust the quantity? of diesel,in a few words, and one of the many senses that has the
the control unit in order to understand what is going on.

Thanks admin, I take advantage of your answer to enter pi? in the specific of the problem and let you know what I would do.
Knowing full well that these detectors are devices that break down and wear out.
So, thinking about the second case: I have a car with a mass air flow sensor is worn, that gives me the most? then the correct values.
To work around the problem: I could simply change the limiter fumosit? in order to make sure that the car lathes to walk regularly, or the low signal also affects other maps?
I don't think that changing do the imitator of smoke you will get the sameThanks admin, I take advantage of your answer to enter pi? in the specific of the problem and let you know what I would do.

performance with a new one,and the problem is that the Maf varies continuously the signal due to the quantity? air intake
so how do you,on a gasoline you have the throttle potentiometer and the other sensors and the address change

But if it were to be only a limiter, modifying it appropriately, we should have performance as new, if not superior, no?
I'm sorry, but I don't understand this sentence!
However, in this case, I am considering a 1.9 JTD with ECU Bosch EDC15.
