Default Rear O2 Sensor tune out

I was wondering if anyone's had experience turning off the rear O2 sensor in Rom Raider. (So that AFR correction 3 doesn't happen).



The reason I want to do this is bc I'm going to run a catless down pipe


In this link it shows how to turn it off in access tunner (they did this to repurpose the input for a wideband

https://www.iwsti.com/threads/2015-s...toring.325464/
Code:

But this isn't available to me as far as i can tell in romraider
My vehicle is a 2013 subaru wrx sti sedan


If anyone could be of help that would be great... If this involves definition files or something special id be willing to pay

Go to the romraider site, under experimental definitions or something like that under the Subaru section. The locations will be there. In romraider option, click the box that shows invalid tables, the right click the missing table and you will see if you are missing the location or scaler or what. The missing info will be in that fourm. There is a thread for each table.

What rom id?

It is a couple lines down from the metadata folder option. I can look when i get off work and see if I have that definition. I have a fully defined merpmodded rom that I think would work. I look.

I was able to find the invalid table in ECUflash. I still don't know how to do this in Romraider (unless you just meant ECUflash).

Regardless you're right the tables I'm talking about are undefined
If you have the definitions that would be great, you've been a big help already

Ok, you are halfway there. The fourm is Subaru Ecu Analysis. I have a merpmodded AE5IB00V fully defined and flex fuel and all that. To flash it you would have to change 1 line with an hex editor to match your orig rom.

These might work, it’s from ae5ib00v
AF3 CL target Comp targets
32f78
2 elements
Scaling-AF3 Lambda
Static -High Low

AF3 correction limits
34b50
2 elements
Scaling-A/F Learning Limits (%)
Static Values-High Low


If not hit up the thread and the info is there or you can ask and they will look it up. Same with all the tables you are missing.

Addresses are not the same between these 2 roms. I can supply the full definition to you for 500V like I did for benflyn’s 000V

Would you be able to share this definition with me? I also have a 2013 STi and would like to modify this table with Romraider.

Hi!

***Edit: I figured it out.

Subaru Forester A8DK100F: 30e10

This is how I did it, if someone else battles with the same thing.

open A8DK100F.xml from rommetada and edit in this using notepad

<include>32BITBASE</include>

<notes>2014/05/22 [Tactrix] Tactrix definition auto cleaned|merged w/ RomRaiderGitHubAlphaMay2014.
</notes>

<table name="AF 3 Correction Limits" address="30E10" type="2D" level="1" scaling="A/FLearning#1Limits(%)">
<table name="X" type="Static X Axis" elements="2">
<data>High</data>
<data>Low</data>
</table>
</table>

Then this will show as editable table under "Experimental" on ecuflash. Now I just zeroed the values and the corrections from RearO2 are gone.
