Single Turbo peeps... what O2 sensors?

Only if they suck dick like the one guys.
I have another set you can have, they could double as a butt plug and mouth gag....
I think the the likelihood of success of any pre turbo sensor combined with the stock ecu is going to be somewhat dependent on the manifold and relative sensor positions.
It's a sensor... the DME has no idea what the manifold is shaped like nor where the sensor is on there. All it sees is voltage / current which gets translated to AFRs and sensor system checks, etc etc.
Fact is ADVs are expensive for what they are ; they work for some but not all and there is no clear reason why.

They are pre-turbo sensors, so why wouldn't placement have an impact, based on pressure differential? It would be interesting to see if the works/doesn't work is evenly distributed among all single turbo users regardless of manifold, or if a certain manifold design/style is more prevalent to having them not work.
Only way I could see manifold design making a difference would be in runner diameter for manifold pressure and proximity to head for temperature.
Because I believe it has an expectation on how long a change should take to be read. A change in fuel that is. Similar reason putting both sensors in the down pipe doesn't work, it expects different values when changing bank fueling independently. I suspect it has a check on time to get that information back also and maybe some ecus have are more complex than others and so there is a difference between who has had success there. I.e. the ijeos might be less forgiving.

@veer90: Did you use copper crush washers to get the heat sinks aligned properly? Or did you just anneal the supplied washer (or just happen to get lucky)? And, did you have to remove the compressor housing in order to make room for the heatsink install, or were you able to get away with removing just the air filter?
I spent about 45 minutes grinding down and annealing the supplied washer--got it down to about a 1/8 turn away, but then the washer tore through. Ordered a pack of these, and they worked perfectly w/ no modification on a DOCRace n54 manifold + HBX-1 heat sinks.

Sorry you guys had issues with them. Moving the manifold o2's to the downpipe on ST cars should at least be a reality this year
Any progress on this?
I'm IJEOS and running ADVs. I'm getting 29E0 (mix control) accompanied by a CEL. i really hope I don't have to switch to NTKs as these ADVs weren't exactly cheap.
any updates Jake?It needs a bit more long-term testing, but it is working great so far
we need to find a solution for the pre o2 issues.also to everyone else,hows the NTK o2's holding up now since its been a while?

You can tune them yourself you just need to use the mhd checkbox and modify the two tables for calibration in the .bin, you have to estimate one of the values based on your turbo setup but it's easy. He can provide the tables/calculation for you or just send me a PM and I'll forward them to you.
I'm running NTKs / Densos and I'm guessing none of that applies to me. lol
Thanks though
Just installed ADV o2s brand new when I installed the single turbo kit. Just over 1000 miles now but 900 of those 1000 I have had trimming control codes (2C31, 2C32) from both banks. I am still on JB4 with a pre loaded BEF. Going with a Twisted Tune once the car is fully set up. Emailed Twisted seeing if these codes are something that can be adjusted and fixed during the tune but haven't heard back. I am about to switch to NTK's because my turbo is out and the o2s can easily be changed out so why not. Maybe some of y'all can give me some input.
