For some stupid reason i accidentally switched the spots for my wideband and O2 sensor in my downpipe so my wideband is after my cat. Would this make the car seem leaner than it actually is?

 

the reading might not be as true

 

yeah i understand that, im just wondering would it read more lean or rich than what it really is, i would think lean but just looking for reasurance

 

I know this from experience, after the cat your wideband will read around 2 points leaner. You want to place it before the cat.

 

what about the wideband they use for dynos that clips in the tailpipe. obviously not as accurate further away from the source, but its still after the cat. idk, just some extra **** to toss into the mix

 

okay thanks guys, just making sure my A/F is on par with this cold weather coming

 

wow man i really wish i could pronounce the city your from lmao

best i can do

 

O-con-o-mo-woc All these Indian names can really trick people.

 

thats a narrowband meter if im correct

 

No, its a wideband. Regardless, if you have a cat and if you get a reading from behind the cat, wideband or the sniffer at the dyno, it will read leaner then what it is , if you have a cat. If you have no cat, it shouldn't matter. Thats how it was with my cobalt.

 

troof ^
