Is that the right placement for the AFR sensor? Also aftermarket header seems to have two holes for AFR (one for OEM and other for aftermarket) for example with J's header, is this correct?

What is the best wideband AFR sensor? Is AEM Uego Kit any good?

Cheers

 

I have mine mounted at the end of the manifold, pointing almost horizontally mounted on the passenger side of the manifold. It made routing the wire so it doesn't touch the pipe tricky, but I zip tied it to the 2 other O2 sensor wires. We'll see how it holds up.

For a wideband, before the cat is optimal, and at least 18" from the head.

Putting the bung on there was a $15 job.

I use the AEM Wideband UEGO kit. I can't complain. Install is pretty easy, really.

 

Zip tie looks ok but I am worried about the cable itself as the route is exposed to header's heat and may fail along the track. If you ask me I am thinking to get myself some sort of flexible conduit and run it through zip-tied with the OEM O2 wire.

If you look at the header image below, it looks to me before the flange there are 2 holes ?? One for OEM and one for AFR O2 sensor? Can J's header user confirm this please?



Where did you get your AEM UEGO? Got any pic?

 

I added mine in the stock header just about like the one in the picture you posted. Its worked great for me for the most part. The only issue I have is after extended periods of running wide open on the autobahn the sensor throws an overheating code. This is after 10 or so km running WOT at speeds between 230-250kph. I need to make a heat sink like it says in the directions. All the time I had it in the states though I never had a problem. Theres simply not very many places where you can run WOT long enough. I'm running the Innovate Motosports LC-1 kit with their DB gauge. I've read a few places that the LC-1 is one of the better controllers, IDK. I've got the AEM on my other car and it's worked fine for me too.

 

Heatsink? Where do they ask you to mount it? When you WOT obviously the heat ramps up to the maximum. Overheating maybe because the sensor calibration is off or some exhaust gas leaks through the custom hole creating pressurised heat? Dunno I'm just guessing there

So you did drill another hole like that header pic I posted?

 

Yes, I drilled a new hole. It's just getting too hot. I doubt there is ANY place in the exhaust that doesn't exceed 900F before the cat on a hard run. I took the stock manifold off to ensure I could run a good bead around the new bung as it's positioned close to vertical. Ideally, the best position is between 10:00 and 2:00.

 

this is when stock header's heatshields become handy - one of them protetcts O2 sensor (among other things)

 

The Innovate LC-1 as stated above is the best affordable kit on the market. Most accurate and fastest response times. The Innovates response times is really what set its apart from all the other kits out there. AEM widebands actually have the most lag, neither a half second or more which would steer me away from one of those which it did. Im running the Innovate LC-1 wideband with the XD-16 gauge. At $300 retail for the full XD-16 it is more expensive but you also add the ability to hook your laptop straight into the gauge and with the record button thats on the gauge you are able to datalog your afr in Innovates log works software. You can also fully adjust the color of each of the LEDs around the perimeter individually to any color you want. Neat feature that really sets this gauge apart from the rest.

heres the best deal i found on a complete xd-16 with lc-1, complete kit out of the box just need to weld in the bung which is also included
