Single Turbo peeps... what O2 sensors?
- Thread starter veer90
- Start date
Some have burned through the NTK's as well although not as frequent as the Bosch. I burned through my originals and another set of new Bosch already. Next set will be NTK. I get your point about troubleshooting but it gets costly and is a pain if they go and you are far from home. NTK's are more expensive than Bosch and It's a shame about the ADV sensors being hit or miss.
Never mind some antilag...
I'm surprised the n54 community hasn't pressed harder for single bank development. Wide band issues, even if just a reliability nuisance, surely outnumber false knock issues by a huge number.
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
Soon?
Hello I am a new member. I have a n54 AT ST DOC RACE 6466 + PI METH + fbo. runing pump gas + methanol ( no e85 on my country).
As a ST I am having so many headackes .
I am running ST since 2200km aprox
I installed the ST KIT and fried bank 1 oem o2 sensors. Then I installed ntk and 50miles after I fried ntk sensors bank1.
Then I tried a kind of spacer ( homemade I think.. ) and I fried bank1 o2 sensor ( I replaced previosuly the ntk by oem bosch).
After that I bought innovate heat sink extender.. so I tried bank1 with new bosch oem + heat sink extender and the old ntk + heat sink extender on bank 2... and I fried ntk sensor.
Last config was two bosch sensor + heat sink extender... yesterday after some pulls I fried bank2 o2 sensor.
So... I fried 3 times bank1 o2 sensor and 2 times bank2 o2 sensors in 2200km aprox.
It seems to be much more often than usual ST users.
As I am running pump gas may be I am having more egts. (??)
I don't know what else to do.
Advs don't seem to be an option for me as some many have to many problems with that and are really expensive. Don't worth it. If they were the solution, i will buy them of course.
Last thing I will try is to put a kind of metalic difusor between the sensor and the manifold. As they are near the turbo and top mount my be they don"t recive enough fresh air... ( as they originally are at the bottom)
Has somebody try this?? Or is it a dumb idea??? I looked that in other platforms
I am just an enthusiastic.. I wish I have a performance tunning shop to take I look. At this point , I just want the car to run despite of the money

My ADVs have been fine fwiw. But they do not seem to work for some people who then usually move on to use the NTKs I believe. Might be worth it.
Reviving a dormant thread.
I myself am still getting codes
2C2E - Lambda probe in front of catalytic converter 2
2C2D - Lambda probe in front of catalytic converter 1
It's more pronounced in the beginning of driving after getting on full throttle.codes come up after off throttle.i would clear the codes and wont come back till a little while after.
I'm using the adv since going single turbo and I have ije0s.from going over this thread again It looks like most guys with ije0s are having this issue so wonder if tuning needs to be different for certain dme's?
I have thought about trying the ntk`s.Or possibly a fix is coming this year.

Take ADV and throw them into the trash where they belong. Then lobby for someone to come up with o2 in downpipe like the rest of us
Thats never going to happen. Thats why of yesterday i bought a 5.3 ls and the swap kit. Now selling the doc kit and all.
that did not take long! good luck. if you by any chance have a good opportunity for exact before and after weights I'd be keen to know.this forum could use a ls swap section to try keep the build threads alive and ls swap knowledge around....
Unfortunately shes already drivetrain-less. Might be able to weigh it complete to compare to another members car stock!

Theres only a handful of ls swaps. But doublespaces might be able to make it happen. If we could get Michael Paige [sp?] On here that would be awesome for more info. He has a 4 part video on YouTube, which helps tremendously, and he sells the brackets! And hes on Facebook, but im 4 years without one, so it sucks, limited info!
Sorry in advance I think I'm over looking this but which ntk part number is for the longer o2 sensors that goes to the manifold? My advs would pick their day when they wanted to work and now they are fried. They max out within 2 mins of running and I keep having to reset adaptions every couple mins so I can drive. Also what o2s you guys using for the rear?
| inches | cm | |||
| CYL 1-3 | AFR722-EE76 | NTK 24322 | 60" | 152 |
| CYL 4-6 | AFR722-EE88 | NTK 24345 | 47" | 119 |
i had this in my files for a few years, worth double checking.
swap the ADVs out. the more I lurk the more I'm convinced they're junk. every single "what O2 do you recommend for ST" has varied responses ranging from
OEM Bosch no issues
NTKs
Densos
Amazon O2s
550i O2s
not a single person seems to be recommending ADVs anymore, except the company that sells them. now what that tells you, is up to you to decide.

Technical - Single Turbo O2 sensor install and data
Thought I'd make a thread to collect some data on O2 sensor options for the single turbo peeps. As everyone knows, 2-bank fueling logic forces ST kits to place the pre-cat O2s in the manifold between the head and turbine, exposing them to extremely harsh high temperature and positive pressure...
