Could anyone explain to me how the installtion of a wideband 02 sensor goes? do you replace one of your existing probes, or do u drill another bung in? O and i had an idea, put a prove in each tube on the header in equal length locations to have a precise reading... would it work? 4 o2 sensors all wireing to 1 harness? just a thought lol

um, it goes really easy, depending on what your doing and which wideband you get.

and to your idea... no dont do it, huge waste of money, and time.. so no, no no.. and how does that make any sense to have 4 o2 sensors and one harness to give a more precise readout? how would sending 4 sets of information or voltages, to one area going to make it more precise, lol..


as for the wideband install, is it one that has a readout? or are you wiring it to your existing harness?

you could drill another bung for the o2, i just took out my second o2 sensor, and hooked up my wideband one there. i havent had the second o2 hooked up for like 3 years with no problems, so i figure i dont need it.

if you have a wideband sensor that your going to be hooking up to your harness, then splice it in and hook up a gauge.

if you have a standalone one, like the PLX m-300 then just plug it in, hook it up to a 12v source and you are good to go.

yah its really simple. They usually send you a bung, a muffler shop will weld it in for you in like 10 minutes for like 20 bucks, then you run the wires.

Also if you are using the PLX M-300 it has 2 outputs one is the white wire which is a wideband output (your stock ecu cannot except this) and the gray wire which is the narrowband output which you can send the signal to your ecu.

I was thinking of using Aem's wideband, and would a highflow cat with a bung in it work? or would my readings be messed up?

High flow cat would work, you could use that bung. There are quite a few options available, I don't know the price on the AEM, but if its more expensive than the PLX, which is like 265.00 shipped off Ebay, then don't bother wit it.

yah the plx one works really good, has very accurate readout, easy to read, and you can tap into your ecu for the narrowband output like tim said, so you dont have problems by taking out one of the o2 sensors.

Carrera

well lets say I were to put it in my cat, would the readings be accurate? b/c im sure the temp of the exhaust would be much less by the time it got down there

hamhead

^^ No. Where do you think they get A/F ratios when your on the dyno? From a sensor up your tailpipe, and it doesn't go very far. An o2 sensor works by comparing oxygen levels inside the exhaust compared to that outside. An o2 sensor only needs enough heat to become conductive so it can take measurements.

just do it the right way and provide a seperate bung for it on the headers... you could always plug it if you don't need it in the future
