where to install wideband??

[2qik4u]

ok I have a 420a turbo and have 3" exhaust running out from under the car infront of the passengers side front tire. I have no cat or muffler and dont plan on running one any time soon. I just ordered an innovate lc-1 wideband and am having trouble finding the right info on where to install the sensor. my downpipe is vertical for about 20 inches before it turns horizontal to exit out the side of the car. how close to the turbo should I run my wideband???? this is a 420a not a 4g63 so I have no original turbo setup. it is all custom built by me and I havent yet put in any provisions for a wideband sensor and didnt put stock sensors back in cause im going to simulate the signal. so I am asking this question because I have no original location and want to know where is is best to put the sensor for best performance.

correct me if im wrong but i dont think it really matters, i put mine right in the middle of both of my o2 sensors. but ive seen people put theirs right next to their first(upstream) o2 sensor.

I might be wrong but I believe you don't want it to be too close to the turbo as it may burn up the sensor quickly. I would contact innovate and have them suggest the best spot for your setup. I put mine at the 90deg bend on my downpipe since I was told it would get the best reading. hope that helps.

The whole 36" deal is a bunch of crap IMO. Many people run their wideband in the front o2 sensor location without problems. It's still an o2 sensor and the stock sensor lasts a long time as well in the front o2 without issues (yes, some of you may say it has more heat sensitive internals but it's proven to work). If you are able to simulate the narrow band signal to the ECU then use the front and free up a ECU port assuming you are able to.

If you choose not to mount up front then mount the sensor at the bottom of the downpipe but in front of the flex section. Be sure to mount it at an angle so condensation doesn't form on the sensor.

i do have a narrow band simulator im going to install for the front o2 sensor but i dont have an original o2 location anymore. i built the exhaust system myself and didnt put the stock sensors back in it at all cause i planned on simulating then anyways. I am going to run the sensor about a foot from the turbo and see how it goes. if i burn it up i will buy a new sensor and move the bung further away from the turbo!! trial and error are not new to me.

I know AEM Suggests 18" from the turbo on there wide bands.

If you are going to simulate the narrow band as well, put the sensor in the o2 housing. You'll have faster response from the sensor which is always a plus.

i dont have any o2 housing. it is a 420a and I custom built the downpipe and the rest of the exhaust.

i agree! good luck man+
