Well, I just found the answer for those who care. The current variations observed on the oscilloscope are due to variations in the magnetic field inside the sensor. The disturbance is maximum when a tooth approaches (positive peaks), and when the tooth moves away (negative peak). When a tooth is mis...

Hello you all ! Could someone please tell me : - why does each sequence start with a peak higher than the others? - is it possible to see the the "top dead spots" ? - Here there are three different sequences: I am surprised because from what I know, in most cases, a single sequence is enough to fill...

my MAP

Hello Vasek thank you very much for this answer, very very interesting. I will make new measurements by also checking the mass, we will see if I get the same results. Yes the sensor is an analogic classic.
- do you use a vacum to apply the discharge ?
Thanks again
Nico

nobody there ?

Hello the picobodies :-) I would like to show you the MAP signal recording dI would like to show you the MAP signal recording of my boat engine (gasoline, electronics). What worries me is that the signal immediately goes up to 4.2v from the start, and stabilizes at this value (very close to the maxi...

Steve, it's just fascinating to read you !!
I'm going to do this test again to see
Thanks a lot, and nice we !

toujours pas d'idées ?

Great, and as promised, i'm back to confirm "yes it works !"

Up, no more ideas here ?
