Same issue here, IJE0S as well. Drove me crazy for months - I tried literally everything including different files that Chris sent over and nothing seemed to work. I switched to NTK and never looked back. Chris was also pretty unresponsive for the most part which made the process that much more frustrating. I've heard others have the same issue as well, but for the most part they seem to work. Still have no clue why they didn't work to this day.
Single Turbo peeps... what O2 sensors?

I don't know and at this point I don't care to know. What I do know is I won't be buying them despite what anyone who sells them tells me.
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

What would stop someone from putting 2 o2s in the downpipe to keep the DME happy right now? I figure it has something to do with having 2 banks and compensations for them, but you'll lose that anyways once you go with a single o2, right?
STFT and LTFT learn apart, then codes, etc. Many people have tried, it doesn't work for many reasons

That will be a big step forward to ST users. Is this something that is complete on your end or in the works? Huge thanks for continuing to advance the platform!
The killer is the bank 1/bank 2 fueling logic, not sure what all changes are required to link fueling together as 1 bank for single turbo but that's what's needed to place the O2s post-turbo.
Also, a short term update. It's been 3 days since I installed the Innovate O2 venturis and I have not had a single O2 sensor heater / function / emissions control whatever bullshit codes that used to pop up before. AFR readings are unaffected just a hair slower to respond.

Let's say it's in the data confirmation phase right now. It's being thoroughly tested on a car with a standalone wideband in each manifold bank, the 2x DME lambdas post turbo in the downpipe, another standalone wideband in the downpipe, a narrowband rear o2 in the normal spot in the downpipe, and 6x EGT sensors (one per cylinder).
The goal of this was long term validation. So far so good.
Two-bank was baked into the roms at compile time by BMW, so no easy toggle to switch it. It's taken a LOT of changes. For awhile I was unsure if it was going to be possible.
Have 4,200 miles on my NTK's with the Innovate heat sinks as described before, no issue. Daily driving, extended idling, 60+ highway pulls, and 30+ dyno pulls
Additionally I figured out my AFR slow response "problem" which was really an install error. When you enable single rear O2, make sure that the bank 1 rear O2 sensor is actually placed first in the downpipe. lmao

Have 20,000 miles of daily driving abuse on my 6062 powered ACF kit using NGK sensors with no issues at all. I don't ever beat on the car continuously for multiple pulls, so maybe that has something to do with it, but been very happy with how long these have held up and they show no signs of failing anytime soon. Couldn't get the ADVs to work from the jump on my ST setup, threw trim codes immediately and continuously for months before I switched and haven't had problems since.
