Wideband Placement Question

[BongRips]

Hey, just a random and probably stupid question. I'm putting in an AEM wideband in the spring and wondering if I should remove the stock narrowband in the O2 housing or leave the stock one alone and then just put the new wideband into the bung on my decat? I'm thinking decat right? And if you put it there, what's the best way to route the wire into the car?

[cschepp]

Your going to want it in your down pipe. I don't think you'll get an accurate reading from the decaf location. I personally would put it a foot behind the o2 sensor and on a different angle. If you do it this way you can just follow the wiring harness of your car and hide the wire that way. This would be the best way in my mind

[BongRips]

Oh ok. Guess I'll grab a new 3" down pipe then with a bung in it. And yea, running the wires from the down pipe would be easy.

Or take old down pipe out, drill and weld a bung in. Deffinately cheaper that way...

[BongRips]

It's just the stocker I think, looks bigger than 2.5" though. I'm doing a bunch of work on the car and while I am on some what of a budget, most the big things like ecu and turbo are out of the way. With the down pipe, I only need about $1700 more in parts and all that is is a timing belt kit, yellow jackets, injectors, fuel pump, boost, oil and wideband gauges, a pod for them and the downpipe. I can do everything except for the timing belt so that saves on money right there, and then I'll take it to a local shop for a tune.

Does this work the same with a twin turbo down pipe?

I have seen 2 sensors in one turbo dump pipe. And another 2 in the other. Ones o2 and the other?

It is OK to put in the test pipe/decat. If you are running a capable ECU in the spring you can chuck the narrow band.

[BongRips]

I'll be running a Haltech Platinum Pro, I'm assuming that its more than capable of chucking the narrowband. Am I correct on this?

[amnash]

this is where i had the bung welded;

[BongRips]

I'm assuming that's your down pipe right before your cat?
