Default Wideband position

Is this an acceptable spot for a wideband install(where I have my finger pointing) or should I move it closer?
I’d be using this to tune and leave it in place.I’ve searched and searched and found all kinds of different places just want to be sure and possibly have this on here for others to be able to search up

I would put it as close to the O2 sensor as possible. Having said that, where you point should work fine.

It's fine in the Y, just try to keep it away for any couplers/clamps that may leak and skew the data. You might consider putting it where the 2 aides of the Y merge so you're seeing both banks.

For best reading put your wideband in the collector where the stock one is and use an extension to move the stock one.

Went ahead and got it all in. Seems to be working. Reads kind of lean at idle and 11.9 WOT on the top.
also, why would you care to read both banks? You can’t adjust bank 1/bank2 and driver side runs leaner anyway doesn’t it?
if I have it back on my lift you all gonna gut me but I used a clamp on O2 bung lol.
also, my narrowband are 90 degrees or in the 3 o clock position in my header collector and I wouldn’t think it would be ideal for a $100 sensor to have a chance of moisture

every setup is different and either bank could read leaner or richer than the other due to fuel distribution and an issue with a specific injector. Unless you're doing dual widebands or you already have a car tuned and doing touch up with just making a quick dyno pull I prefer to read at a point that gets both sides.

you seem to be quite versed. I have the aem 30-0300 uego x or whatever it’s called, I’m logging via analog. I’ve got the 3 ground wires all grounded together with terminals. It’s reading and I have it setup in the scanner and logging, in hpt it has an aem 30-03x0 in the wideband selection, would you happen to know if that is right? I’m just one to double check to make sure I have the conversion fuction right and it seems the paperwork I have from aem lists the values in a different format..

I don't use AEM wideband, but if you Google AEM wideband with HP Tuners it looks like there are quite a few setup videos. I will say that all sidebands I've seen have you separate the sensor/controller ground from the gauge ground, but maybe the AEM doesn't so that.

I’ve looked but I’ll go ahead and look again to double check. interesting on the sensor grounds, I actually was wondering before wiring in my prolink and found some people having logging issues that were advised to use a common ground for the power,sensor, and prolink so that’s why I just went ahead and did that..if it’s reading then I guess it’s right lol. But I can easily change it with a simple machine screw because I used ring terms on all ends. I’ll have to do some more searching on proper wiring of the prolink.

Did you seal up the clamp joint with something like Wurth exhaust paste? You want the sensor between 9 and 3 o'clock on the pipe, between 10 and 2 preferred.

i used the stepped mega clamps on the slip joints and my clamp on bung is a band clamp( the one from AEM) that included some kind of thick gasket material that encompassed the entire inside of the clamp. I drilled out the pipe with a step bit to the point it likely wouldn’t leak much even with no gasket(really snug press fit to get the bung locator into the pipe). The sensor is about a 2 o clock. The hole I have drilled for slave bleeding was perfect for my wires. Gauge is in the driver side vent in the center console.
