Diode trick auch bei AHU?

Ist die diode trick (fur LMM)auch moglich bij eine Passat mit AHU motor?

Ja, ist definitiv möglich!

Das liefert aber auch die Suchernfunktion, den der AHU ist identisch mit dem 1Z.

Hmm ok, so eine AHU is geleich an eine 1Z
Has do auch bitte ein link vor mir? Und pic`s von ein AHU LMM mit mod
Das is doch eine pierburger?
Entshuldigung vor meine deutsch ich bin eine newbie as holland
Thnx any way

Nein, habe ich beides nicht. Kannst du aber vielleicht über die Suchenfunktion finden.

Ja

AHU ist 1Z und die haben beide den Pierburg:

Bilder gibts, wenn mein Server wieder da ist.

Ok danke vor ihre information.....

Vielen dank vor diese pic`s
Abe noch ein paar fragen..
Has do auch der komplete LMM deraus gehalt?
Order nur die diode gefixt.
Kan ich auch das snowscreen entnemen?
Momenteel ist meine MAF actual im VAG-COM 847.9 sal das hogher werden?
Thnx a dutch newbie

Sorry, so ganz hab ich nicht verstanden, was Du wissen willst.
Schreib es ruhig in english, das duerfte fast einfacher sein.

Ich fahre wieder mit dem orginal LMM.

Beim Dioden Test haben ich am LMM nichts geandert, der bliebt einfach elektrisch tot aber mechanisch vorhanden.

Die 847 mg/H sind das absolute Maximum, hast du das auch bei allen Drehzahlen ?

Bei mir faellt der Wert ab 3000 U/min deutlich ab und die Einspritzmenge wird zureuckgenommen (Spalte K ist das Minimum)

-----------------------------------

I'm now running the car with the original sensor again.
I did not change the airflow sensor.
While testing with the diode the airflow sensor stayed untouched in place, it just had no electrical connection.

847 mg/h is the maximum you can get. But do you have this value for all engine speeds

My actual value decreases over 3000 rpm and the injected qualtity is reduced. (column K is the minimum)

Hehe

Sorry for mine crappy deutsch.

Lets try this conversation in English ...
What a realy want to now if you put the diode in place did you removed the LMM completly?
And put some other tube instaed. ( beter airflow i think..)
Is it a option to remove the snowscreen from the LMM (again beter airflow..)

I`am driving around with a `97 Passat with a selfmade powerbox see this site:
http://tditech.tk/ sorry but it is in dutch.
I`am very pleased with it.
But i want to try to get more air in the engine.
Maybe bigger airinlet (RAM-air)
Mine MAF actual is 847.9 constantly from @1600 rpm till @3700 rpm.
What i understand is this the max. value for the ECU?

Thnx for your help m;

You don't need more air

Der EDC is only build for a max. of 847 mg/R.

I did and will not remove the sensor - the car has to look like an ordinary one

If your powerbox demands more air, you should try to patch the manifold pressure sensor (like 10 cant tuning) to sent the specified pressure about 0.1 bar higher.

But don't try this without a boost gauge !

m;

Oke that`s claer to me..
So it`s not realy necesary for me at this time to cutout the LMM and foul the ECU with a diode.
As i say mine MAF actual is 847.9 that`s like new i think.....(it`s 7 years old now)
And what about removing the snowscreen....
I dont now anybody with expierience to patch the manifold pressure sensor..
Is there some info on this site i will use suche in a minute
Thnx for you replys m;

Hallo to all..

I heave a AFN ad drive around with the diode mod in place an I think te car feels less restrictve specialy wit the box on and there is less soot output.

If the diode is causing this effect or the K&N wit the fully open maf tube (no screen and no sensor) I dont know...

http://www.home.zonnet.nl/leeoscar/images/lmm/LMM4.jpg

I'am running around with the idea of taking the map sensor signal and put it on the output pin of the maf.

The Idea is that the injected quantity will be reduced when the pressure fails..so it will be a littele more safe as with the diode... only

I dont no if anyone tryed this already an how the singnals compare...

And my Car looks like an ordinary one under the hood...

Exept for the fully removed EGR system ..

Hello Martin,

Is it then possible to dial up they amount off mass air flow via OBD, lets say
from max value 847---> to whatever kind of higher value?
I now a guy with a Passat AHU (chipped) with a actual MAF from @980 mg/R
Or do you realy need another ECU at this time.
And the removing of the snowscreen... is that a option?

Thnx

If your EDC now runs with a max. of 847, you will not be able to "set" is higher in any way.

If you know someone with an AHU and 980 mg, please check his maximum injected quantity - I thimk hiy EDC will not inject more than yours - otherwise he will not have an normal 90 PS machine (more Diesel -> more Power).

I know the AFN was build with Pierburg and later with BOSCH air flow sensors, maybe the different values (not up to 1250 mg/R) result from this change.

Don't worry about the 847 value, if you use a box, the value is of no interest, cos' your box will change the inj. qty. anyway

I don't know, if removing the screen takes any (positive) effect on the real air flow.

Did you close your EGR (exhaust Gas recirculation - deutsch Abgas Rueck Fuehrung) ?

If not, this would be a much more effective way to get a little more power (or spontaneity) - how to do this is described in german in many threads here.

Thnx for your reply.. Mine EGR is closed and even the KAT is empty.
If I had a spare LMM i will try it, but if you once removed the snowscreen on a LMM like mine it`s difficult to put it back again.
I hoped some one as expirience with it on a AHU
As you can see on the pic of Luc`s LMM his snowscreen is removed and he is positive about it.
But he has another type of LMM (bosch) and engine (AFN)
Thnx again
