Thank you for clearing that up, attached my stock rom pulled from my car.

I've been trying to learn more about open source/xml/hex over the last few days and tried this myself, I've gotten as far as getting hex editor, finding the address that seems to be where the af3 is but don't know how to implement it into romraider definition yet, or even see the actual value, HxD is freeware, is there a decent hex editor i can buy to do this stuff for personal use? not looking to spend 1k though lol

Opened definition in Notepad ++ , I can read and sort of understand whats going on but I added the table from the first post in this thread with no change

.

Offsets I found
3B2F8
3C2C4
3CE78
3D990
3FAF0

Thank you guys

Did some digging and compared/based search off my AE5T200V. These seem to be correct for AE5R100V, someone please confirm? Shows up as it should in ecuflash.

Hi, since I'm having some weird afr problems with my supercharged ez30, I wanted to totally turn off AFR3 correction...

Can someone confirm if the correction limit table address for D2TB201L is 36190? Also, my lack of knowledge can't manage to find CL target compensation limit table? And are there any more tables connected to those?

Hi cortin, thank you so much for doing this!
One question: Is there a location for "AF 3 Learning Limits" in that rom (AE5T201V) by any chance? I've seen some say you have to zero all three tables to get the O2 delete to work correctly.

I ran with those two zeroed out and it turned off af3 checked in logger.

Can someone confirm me the address(es) for A2WD012A?
I looked up the string 3F 00 00 00 BF 00 00 00 with hex editor and came up with 2B74C, but is this the correct one?

EDIT: found the tables from another thread for A2WD012B, the addresses are the same

Code:

<table name="AF 3 Correction Limits" address="2B74C"></table>
<table name="AF 3 Learning Limits" address="29010"></table>

<table name="AF 3 Correction Adder (Increase)" address="65750"></table>
<table name="AF 3 Correction Adder (Decrease)" address="6574C"></table>

<table name="AF 3 Correction Adder (Increase) B" address="66410">
<table name="TPS Opening %" address="663EC"/>
</table>

<table name="AF 3 Correction Adder (Decrease) B" address="66448">
<table name="TPS Opening %" address="66424"/>
</table>

Looking for addresses for AE5Z321V (2019 USDM STI). Help is much appreciated!

EDIT: Im guessing these might be wrong because the car wouldn't start. I tried flashing back and bricked the ecu. I'm thinking I need to get this half tuned and sell it. Way too many problems trying to diy stuff because a tuner wont risk their livelihood by crossing the epa.

I have A8DK100X and found the addresses of 30E10 and 2EE90 in this thread somewhere. I added those and they turned blue, and can open them it in ecuflash, but I don't understand how to zero it out. I have been trying to figure out how to use the rear o2 for a wideband all day and could really use some help if anyone could spare some time. Thank you

I believe it's address: 3a740 as I see what seems to be two subroutines directly prior, but it might be 39bc0... I'm new at this

Can someone confirm?

EDIT: I'm fairly certain it is address: 3a740, as I have the 0.000019073486 float preceding the subroutines as well.

Can anyone help me find the rear O2 correction limits on my E2ZJ111H rom? My rear O2 is throwing fluctuations between -2.5 and 2.5% fuel trims currently which of course is affecting my fuel mileage. I've included my stock ROM which unfortunately is not on the stock ROM list.
I've found some addresses in HxD to be:
1F384
1F808
20D98

Any help would be greatly appreciated.

Thank you for the reply cortin. I was under the assumption that 1F384 was the correct address. Hoping this resolves my issues. I have a log of the corrections while driving as it sits now and I will log after this change to verify.
