wideband bung best weld location ??

[xs man 27]

hey guys I gotta get my exhaust fixed soon and while I am at the muffler shop I figured I ll have them weld in the bung for my innovate wideband gauge .. can anyone tell me where the best location for me to tell them where I should and where I shouldn't have them mount it ? I m trying not to do it on my mid pipe beings its a h pipe and in the future I may switch it out for an x pipe. thank you for any input..

I have bbk full length headers into a bbk or h pipe..

Are you using a kit that uses lc1's or the lc2 controller? If so, they both have outputs on them to simulate a narrow band gauge, so you can use the same o2 sensor for wideband and ecm feed. Looked up the other kits innovate has, and most of them have fully programmable outputs also.

I got the innovate mtx-l series wideband gauge.. I believe the one I am using is the lc1 but I could be wrong.. any more input be great thanks..

 

[kb1982]

The mtx-l has a self contained controller that does utilize an lc1 r 2, which simplifies things. But is does have 2 analog outputs, one of which is designed to simulate narrow band outputs. Heres a link that will tell you most of what you need to allowing you to run the wideband in the stock narrow bands position. http://www.innovatemotorsports.com/support/manual/MTX-L_Manual_1.1.pdf Only thing you need to find out is which wire is the signal wire for the ecm.

I would just uhh se a new bung.. sometimes wide bands like to throw fits. You have to recalibrate and crap.. new bung about the 2 oclock..

The instructions will typically provide guidance on bung placement. Mine is on the passenger side, about 2" down from the OEM bung, and in a location where moisture build-up should be a non-issue.

best place for long tubes is generally drivers side in the header collector, usually in the top half of the pipe a little above the midway point.

 

[rz5.0]

Driver side usually runs leaner. That's where you usually want it.

AEM advises it be roughly 24" away from the exhaust port.

can i instead of going to a shop to get the bung for my innovate wideband gauge welded,, screw the probe from the wideband into my 02 sensor that's already on my bbk longtube headers and it work ?

i find this interesting. everything i've ever read says the closer the better.... strange.





anyways, from *my* experience:

You want it as close to the header collector as possible, in the collector is ideal.
You want to place it on the "top half" of the collector -- this helps with condensation after the exhaust cools off.
You want to use a new bung when you have it welded in, not a used one.
paint the weld after its installed to prevent rust.
GROUND the gauge well -- Auto Meter suggests grounding directly to the engine.

Yeah I called AEM and talked to one of the reps just BS'ing about different locations and whatnot. That's what he told me for distance. Basically, the end of a long tube header would be great according to AEM.

I've heard of guys removing their rear o2 on the driver side and using that since the rear o2's are off... Not sure how great of a spot it is but hey just passing along some info. Someone can tell us how bad of an Idea that is LOL

 

[MustangChris]

if they are not heated sensors, thats an awful spot. I know my autometer units were heated, but not sure how well they'd read info that far back.

No Idea MC.. I have an AEM myself and I do believe it's a heated sensor tho don't quote me on that. I'm fairly clueless on the subject which is why I posted that, more or less for my own personal knowledge. Mine won't be installed until I get my hotside kit, at which point I would install it on my down pipe, but I know my buddy has the same wideband with his vortech and I think he ended up putting it in an old o2 spot. If it's no good I'll have him move it..

[MustangChris]

have him move it. It's behind the cross-over pipe, too. He's getting readings of mixed exhaust from both cylinder banks. ... ... the readings he's getting are worth very little, as far as I'm concerned.

 

[kb1982]

The innovate wibeband o2's are all heated, they use their own controller to heat them and calibrate them. They use the Bosch LSU4.2 5-wire sensor. The innovate controllers all have analog outputs, which 1 of is set to simulate voltages for narrow band operation, the same as a stock 02. The ecm wouldnt be responsoible for heating or calibrating the ecu, but can still get the signal it needs for operation. If using one wideband, throw it in the driverside header, and connect the analog output to the wire that carries the voltage signal to the ecm. You can then just run a stock o2 in the passenger side header position connected as normal.

Same O2 sensors with the Zeitronix system. WB sensors don't like super hot temps that are needed for the NB sensors. Zeitronix instructions are a minimum 18" from the collector.

/\ this is how my Zeitronix system is set up. drivers side roughly 19" down
