Great, I've just done all this, so as a reminder :
- put the rear o2 sim
- set the rear o2 in the periphery bit to 1
- disable the rear o2 heater by setting it to 0009
And it started display low LTFT.
Nevertheless, she doesn't want to enter closed loop under 1200 rpm, maybe because of the kelford 272 or the size of injectors DW1000, or should I change something in closed loop settings ?

I think I've found the adress for this table. I'm using 35e5 on a 96530706.
I can read (from stock I guess, never changed it)
Low to Mid 75
Mid to Low 62,5
Mid to High 1587.5
High to Mid 1581,25
But what should I do with it ? My trouble is that on idle lower than 1200 rpm, the ecu won't close loop (0 o2 stft reading and AFR off from 14.7)
At around 1000, I'm idling between 37,5 and 43 Hz

Hello,
I am running into the same issue, where all my trims are reading zero. I have done the mentioned above and also checked if I am in OL all the time and that doesn't seem to be the case.
I am on SD using 9417 with S3 cams.
I reset the battery, and let it idle for 5-10 mins and no luck on the low trims. Any idea what maybe the issue?
Thanks
edit: worth noting that I have my rear o2 removed and disabled.
