Hello. Did somebody knows, what is correct Evoscan voltage displays for nb O2 front sensor. I can't find it anywhere :/

 

Tomas, you mean the value that you want at WOT or the scaling? It should be in the ECUflash forum, but the NB voltage is typically in the .917-.936 range.

Aaron, I was sent You email but I'm not sure You get it ?

I'm still fightin with my idles. It look like this sensor is dead (someone from this forum seen my log), but i'm not really sure. So that's why I need this value for idles.
Ofcourse I'm talking about Evo 9

Can you post up the log again? I got the email but didnt see a log attached. If you are getting no voltage at idle or "stuck" low where its .03395 or something like that I would say dead sensor. Is it cycling, that is moving between .19v and .97v on its own? Are the O2 feedback trims working?

 

Here is screen from my Evoscan:

 

This is very important for me anybody have some ideas ? Are my values correct ?

If the NB isn't cycling at normal operating temp it is most likely dead or problem with wiring

 

Thanks for answer. I guess, that my o2 sensor is working, because I've tested it with traditional voltmeter. The problem might be in wiring, because my car is sooo custom and ECU's not seeing this sensor: / I think I have a lot searchin to do with my spagetti...
