how-to: control closed loop AFR with your wideband O2 system
buddy helps me port this patch from 8859 to 8858.
i have only one idea how to test - use Evo Live Map. so i patched this rom with DMA.
so... it's work. i can't tell you well or not, but work.
if someone want check and can test - you are welcome
in fact afr swingign on idle. if i set 14.7 - 13.8-15.5, if i set 15.6 - 14.7-17
i haven't enought time to much testing. i can't say that with zt2 o2 simaluation afr much solid or not. seems +|- same.
i'm not 100% sure in right port.
afr can log from MUT3C and MUT12
mrfred, do i need disable o2 rear sim in v7 tephra options?

Implemented this yesterday and all appears to be working fairly well.
Cruise AFR set to 15.4 and I"m getting swings from 14.7 to 15.9.
The only problem I see is much slower cycling times, in fact slow enough to trigger a P0133 Slow 02 response code daily.
Any way to speed this up or is entirely dependent on the speed of my Uego?

Could someone please help me out?
I am trying to add everything to the 88590015, it showed up on my rom although I seem to be doing something wrong:
**I apologize in advance, I am a total noob. All this makes my head spin and I am trying to get around.

Trying to decide between buying a new sensor or replacing the system.
Are others getting fast cycling using an AEM Uego?
I played a lot with the patch and the sensors . With the stock NB and without the patch the closed loop afr is so tight at 14.7 !
With the patch and aem uego sensor in downpipe bend after the o2 house cause quite large oscillations with the same setup ! Swing between 13.5-15.7 all of the time .
Moved the Uego sensor in O2 replace the front stock NB to see the result. Oscillations maybe a bit tighter but quite large compare with the stock NB .
Fuel trims were different in every 3 situation. STFT oscillating least with the stock NB .
Any update against the oscillations would be cool

I have the same problem with an older sensor, how old is your sensor?
I'm thinking of buying a new sensor, but would rather get a new WB02 system if the Uego is simply lacking the speed required for this mod.
I am having this issue also, fresh sensor. My 02 sensor is about 18" from the turbine outlet. I also wondered if putting it closer would help, but based on what you say it won't.
It was a while ago but I was using a UEGO during the original testing of the mod. It worked fine.

Closer will always help tighten the oscillations, but make sure the sensor doesn't get overheated. WBO2 sensors cannot tolerate as much heat has a NB sensor. Innovate claims that their WBO2 sensor control software is much faster than the competitors.
