Emulator lambda probe

[rego88]

this morning I was doing my tests with the above scheme on a opel combo 1.6 petrol... but the thing I don't see it very efficient.... or I'm wrong.... or something is wrong.... in the sense.... here it says.... grey wire and black wire.... it does not specify which one ? voltage 5v and which one ? signal.... I tested the resistance on both wires, but I don't see much improvement in diagnosis.... ori I find 700/750 millivolts in the diagnosis, after put the sort, with the resistance on the wire of the 5 volt, and I am at 670 mV.... I think is not enough not to turn on the light.... as the original with kat efficient should give a maximum value of around 450 mvolt....

in practice... something f?.. but it is not enough to emulate the signal to the full! .and if you increase or decrease the resistance?

correction guys... I was wrong I read the value in diagnosis.... the probe is not a right... it remains to share 1064mvolt.... the maximum value.... I have not tried, however, to the contrary...

But the minicat goes well on any probe post cat? do you know if someone produces them in Italy at affordable prices?

[alexm]

that I know, to fool the ecu just make a voltage divider... and fix cos? a value.
on motorcycles doing so?... on the drive I don't have experience.. but if the probes are the same, why? no..

Mmmm.... Interesting discussion! If I build the minikat at the head of the screw is to see a screen, which would it be? Can I leave it fully open the screw, no??

[Mr.Flash]

no, absolutely not .... what seems to be a retina really? ? a mesh of elements, captivating , exactly as present in the catalyst , which serve to catalyze the exhaust gas so that the oxygen sensor to see them properly processed , and do not turn on the error.

In italy, sells the bonalume and costs a lot of money .

I have mounted a dozen, and they work well, even very well. In 99.9% of cases it resolves the problem of the light. I also tried the emulators electronic but I have almost never worked except in rare cases, management electronic latest.

The mini-kat if you have a lathe, and so easy to do

interesting to Admin!!!! how do you recommend I proceed ?? You would use as a material catalyzing an old catalyst (but ceramics as well as the would you work?) or you have metal doped (such as metal catalysts) ???
