How to build the module for the air mass meter

[dvdtuning]

Could you explain to an ignorant like me, what is this form?

[dvdtuning]

But it has a manual control right? adjusts to fumosit

But it has a manual control right? adjusts to fumosit??


now I don't mind the one posted but it should have a trimmer to adjust the signal.

[dvdtuning]

It has a trimmer...in fact, I was wondering if you have to find a compromise between performance and fumosit? or ? in continuous manual adjustment?

then, I'm not, I've never used it built pero I think it has smoke; hence' but the values in the diagnosis, you should know the standard values, and then set accordingly.

[polini]

the smoke center why? if in theory we read more? air control unit sends ir? diesel to compensate for....

you but you can't deal with the smoke, but with the standard values that should have.

[demolitionMan]

then if we read less , the amount of air should increase? the butterfly electronic mosula the flow of air opens, right?!

[nicospl]

it should be so

[tezzero]

forms the so-called salvadebimetro use them for years to be good enough ,you use a trimmer for the adjustment, there are three wires or four wires, namely :model 3-wire stops the signal of 5 volts, which provides the controller to the mass air flow sensor while in the four-wire stops the output signal from the mass air flow sensor discoverable always with multimeter..with the engine running at idle at about 1,8 2,2 volt acceleration increases..being broken should not reach 4 volts. The best of course, these are 4-wire applicable on almost all of the debimetri i.e. analog 5-wire...

[ecuboost]

for the digital ones c'? something to do with it? the fiat bravo 1.9 mjtd 120 bhp 2007 do you know what mount?

[tezzero]

Who knows for digital there are no alternatives

Practically these modules are used to restore the debimetri worn: they are a sort of signal amplifier. In fact, with the time the debimetri (being a hot-wire) subject to wear, and these circuitini serve to restore the correct value of the voltage that would be provided by new!
To calibrate them properly serves for? the use of a computer shop for diagnosis and adjust the trimmer so that the theoretical value and actual value of the match! Them you could do with a multimeter, but only on condition that you know already? a priori, the correct value of voltage that should provide new...
There are both petrol engines and diesel, but usually are not really cheap so thanks to the admin for giving us the pattern for them... :)

[albertorapper]

yes, but if you don't have the mass air flow sensor not you can install them right?

[luigigtc]

I think that the mass air flow sensor have all the modern cars with electronic fuel injection, a friend of mine on an alfa gt 16v mjet, he used it why? had yield problems of the engine, I don't remember any of these problems, but putting this in the emulator, it has solved almost all the problems it has,

[tonyteam]

curiosities? reviving this topic:but I read about modules, mass air flow sensor +50cv...even if they were only 15 or 20cv, in your opinion ? possible to read truly values in + the mass air flow sensor? the cio? the ecu avr? also tables scaled to the maximum for 1300g/S... if the law does not generates recovery?

I have someone built and tested on a 147 and the bmw 530d with good results,the pattern ? what is online 3-wire,probably the one with 4 wires ? best when the mass air flow sensor just the nonce is pi?...

Never tried on the Golf V?

[sportknight]

no, but you should go on the same

Guys has anyone tried to use the form that is on the first post of this page ? In addition to the second pin of the 7805 c' ? written diodes generic ...... which to use ? and finally, next to the pin 1 of the 7805 c'? written 1N4148, what wouldst say : that you need to add a diode 1n4148 on that branch?

[sportknight]

you have to use 2 diodes in general subject to availability? the dealer(not a joke) the written 1N4148 do not consider..

But you already tried that module?....*****s, diode-there are many, in a shop specialising in electronic components I can't say give me two diodes generic ?

[sportknight]

of course I have tried and it goes to the great,for the diodes, I said, I own two diodes general ;)

Hello, I did as you said ... I asked two diodes generic !! I have now built the module .... but how does it work ? from the diagram I can see that I have to insert the module between the control unit and the mass air flow sensor but in what way ?...... carving the wires connecting the control unit with the module ?

[danny677]

The power supply + and - them, you just have to intercept and splice the power supply to the secondary circuit of the flow meter placed at the pin no.4 the need to stop and the flow meter must be now powered by the thread of the current transformed from a 12v ( taken from pin 2 5v and something..
however, give + volts to the secondary circuit the resusciter? for a little ( giving you some benefit ) but at the end brucer? all of the resistors contained within because of the increased voltage..
also not ? very precise method, as the build is good the voltage ? never as stable as the one on the 5v and sends it to the ecu, to vary the operating temperature of the circuit s'? made and the current load of the 12v that powers the blade hot varies? and not just the voltage given to the mass air flow sensor x you barcamenerai between moments in which the flue gas to the chimney in moments of empty delivery..
the circuit that acts on the signal, s'? mentioned before ? stable and place it on all the analog and sundry ( there are 3, 4, 5 and 6 pin ) .
For the debimetri digital c'? one of the bmwpassion that created it and it says that it works but still has not put on the market

[angelus.d87]

Sure are you? Xk I qst nn I can see but I have built a modifier signal x a point jtd
And practically the machine is switched off the signal in volts should be between 1 and 1.2, and this also serves xk when the mass air flow sensor nn works on the pi? from a low signal..
With this good or bad, we can compensate for
in fact, with a mass air flow sensor nn functioning of the air measured at 700 instead of air objective and 1200 a minimum time with the air module measured 1000 then anything.. And then I noticed that the mg injected decreased from 8 to 6.5 mg

I recently acquired the privileges to be able to see the attachments and seeing this form, I was surprised in the sense that I keep it down? from a piece
mounted and substantial differences not known if not a slight but perceptible brio more at high rpm.
I'm trying to build this, that I believe is more valid for a possibility? adjustment.
someone has already? tried?
