Can I get some assistance on locating the addresses for the rear 02/af#3 corrections for any(all?) of the 2012 USDM Sti rom(s)? CAL ID's are AE5K500V/611V/700V/800V

I am working on editing 32bitbase to disable my AF#3 on my A2ZJ512I rom (04 FXT).
I entered the address for:
Correction_Adder (inc): 5D55C and got default of .00350
Correction_Adder (decrease): 5D558 and .00500

AF3 Correction Limits: 293C4 and got defaults of 50 and -50
AF3 CL Target Comp High 26E68 defaulted to .5
AF3 CL Target Comp Low 26E6C default: -.5

Those appear to be correct based on the returned values.
Is there an address for AF3 Learning Limits or is it irrelevant as long as I zero out
the 5 tables/addresses above?

Thank you very much for your input.

Hi Guys,

I'm working on optimizing my ROM and that is how I stumbled upon this thread. I'm trying to disable the rear O2 AF#3 corrections(running catless without rear O2s).. and I had success - well to some extent.

I found 6 occurrences of the 3F000000 BF000000 string. Added the addresses in the ECU flash definitions and voila I was able to see the values -50/50. I zeroed everything which fixed the bouncing AF#3, however it looks I disabled all sort of corrections/compensations :lol: .

In the first post instructions there is another string that should follow and it is 4F22C79A F808D59A however in the 6 results I can't see this one. Closest one is 4F 22 D0 89

I can do brute force going one by one, but decided to ask as someone might be able to help me out :roll:

These are the addresses I found.
219F8 21EF0 229C4 23414 237CC and I suspect the correct one is 24F6C

Any suggestions are welcome! Thank you in advance!

ECU is D2WD701C ECU ID 3C4A384106 - EDM Legacy spec B 2005 6MT


:!: EDIT 30/08/2020 I found the address to be 23414 I hope this would help someone
