Wideband with hf mani question
 

From what I have read you need your wideband o2 sensor a decent distance from the turbo, Although there is a spot for the o2 sensor right on the hf manifold. So is it ok to put your wideband in there or should it be after the turbo? You would think the reading would be more acurate in the mani but will the high temps wreck the sensor? If you are using an hf mani could you tell me what you did and how it works, thank you.

you CAN use it...

you SHOULDNT use it...

sensor will fail prematurely

Re: Wideband with hf mani question
 

what I suspected, I think I will just put the narrowband in there and weld a bung in downstream. thanks for the reply

Re: Wideband with hf mani question
 

Says in most WBo2 manuals not to do that!!!

You don't need a Narrowband. Open Loop all the time!!!!! Just plug it, You'll probably through o2 sensor codes with it there!

Re: Wideband with hf mani question
 

my old coupe ran the narrowband in the hf location, it never threw codes.

Re: Wideband with hf mani question
 

Ditto

Re: Wideband with hf mani question
 

if you are tuned you dont need a narrowband, and the tuner probably disabled the o2 sensor anyways thats why you didnt throw a code. i have seen a few tuners actually use a narrowband and spend a little longer setting the target lambda and all, but its usually just disabled for boost.

Re: Wideband with hf mani question
 

it's always disabled for boost because your foot is usually pressed down pretty hard then.

Re: Wideband with hf mani question
 

well, true, but i was saying its usually manually disabled w/ the tuning software.
