Wideband Sensor Location
91 / 6 speed / L-98
Running Lingenfelter headers with 3" y-pipe. I was wanting to put the sensor bung in the y-pipe right at the y where the pipes meet. Just wondering if this is too far back from the heads. I've read you do not want to be too close to the heads or you will burn up the sensor, yet they are more accurate if they are as close to the heads as possible. Wondering where everyone else placed theirs?
Thanks

you're probably NOT going to burn up the sensor in a N/A situation, regardless.
However, since the wideband sensor is self-heated it's location is not as critical and the front Y-pipe location is a commonly used position. You'll be fine, just double check your clearances to the transmission pan, and make sure to orientate the sensor so it's pointing slight up so condensation/oil/whatever doesn't cause a problem.
BTW, what wideband are you using? The Innovate LC-1 can actually be setup to replace the stock O2 sensor (I've had decent luck with mine so far).

I'm using the LC-1 as well. How did you set it up to replace the original sensor? The reason I wanted it in the y-pipe was so it would monitor both banks. I do not know how important that really is.
Thanks for the reply

Make sure that your cable going to the sensor can not get close to anything hot.

# 7 cylinder runs the leaness, the best place for a bung is coming out of the # 7 header pipe as it comes out of the head. if you tune to get # 7 right, you will never be lean on the others.

Regarding the LC-1 emulating the narrow-band O2 sensor:
It comes setup that way on analog channel 1 (0.100volts to 1.000 volts with a range of roughly 14.0 - 15.0 AFR). You just have to setup all the wiring as normal, and then pipe the analog #1 out directly into the stock wiring harness (where the original O2 plugs in). That way, when you datalog the ECM it's using wideband volts rather than the switching narrowband.
It's in the manual - page 18-ish I think. Try the website to download the manual if you need one.

You can place a WB on a NA application and over heat the sensor. I've never done it before but I have a friend here in charlotte that is struggling with that on his FM13 stock block LS1. I almost think its a controller issue but evidently others have had this problem also.
I would try to place it as far forward as possible, don't worry so much about heat as that you get the placement right (something like 11 o clock to 2 o clock) so the sensor doesn't collect water and keep it away from flanges that can leak before the sensor.
