So, I decided its time to monitor my AFR's and picked one of these up.
I didn't realize that it needs to be integrated with the ECU to run correctly. i was under the assumption that because i'm running closed loop i could just screw in the o2 sensor add some power and bingo bango I can see whats going on.

upon further reading it seems its not that easy. can i get some clerification on the necessary steps i need to take to properly install this system on the car? i do not have access to make any changes to my ECU.

am i able to use this guage as solely a monitor for the time being? does it really need to be connected to the ecu?

 

Not entirely sure here, but I think you will need to hook it up to the ECU only if you are replacing the stock narrowband with the wideband. Why don't you just do that and hook it up to the ecu? I'm sure it would be pretty easy.

 

i thought with closed loop the ECU isn't even reading the narrow band any more?

 

No, it doesnt need to be wired in to your ECU. And to drive the point home even further you wouldn't want to wire that in to your ecu with out establishing the parameters of what voltage equals what lambda. With out that, your computer determines nothing of value.

Just wire the power and ground, drop the sensor in, and observe your AFR. Easy as that.

 

THAT IS EXACTLY WHAT I WANTED TO HEAR.

i love you..

and will see you next week.

THANKS.
