    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?

    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 ?

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

    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 ?

    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

    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?
