Im currently hunting for addresses to delete Sai secondary 02 and cats on a 12v vr6 I own. 021906018r I have hunted for a xdf and .kp to use. Maybe I am just an idiot or missing something but if someone could help me find addresses for what I need that would be great. I looked on the S4 wiki and I would assume those locations(addresses) are not going to be the same on my ecu. If I am incorrect please school me. Any help would be greatly appreciated. Tia.

you can start with:
CWKONABG 8bit -> 181B3
CWKONLS 8bit -> 181B5
CWSLS 8bit -> 181B9
and create your own xdf/kp

Thank you I appreciate the help. Seems to me like the address for CWSLS is coming up with a strange calculated number. What am I screwing up?

bit76543210
CWSLS in your case "136" -> 10001000 -> bit3 and bit7 are true -> 128+8=136
Coding for every bit is defined in "FR"
but...for know, if you want to keep it simple, just disable SAI(SLS) by setting all 0
there might be some more "parameters" to get a clean delete of SAI and secondary O2 ;-)

You really have been an incredible help I do appreciate it. How would I go about finding more addresses with out having to ask someone on here every time? I'm sure it's quite complicated like everything else related to this process but we are all here to learn right. Thanks again.

assuming you already removed rear O2 sensor and SAI components,
did you already changed the coding of:
CWKONABG
CWKONLS
CWSLS
and what is your new coding look like?
Any fault codes appearing?

tried to flash this file to my ecu today ran into a bit of a road block. Its a 400bb ecu. I opened the ecu to double check after running into this problem. Nefmoto is coming up with an error saying I had the wrong memory layout. I changed it to 800bb and it read the ecu. the hex looks like two copies of the file I posted previously. I didn't want to write a new file but Ill post text of the session and ecu data.
Reading ECU flash memory.
ECU reports programming session preconditions have been met.
Negotiating communication timings.
Timing negotiation failed. Communication timings are unchanged.

I ended up grabbing a spare ecu. I did an immo delete. I tried to write with nefmoto, no luck (bricked). I had to flash in boot mode with mpps. I am just trying to deal with the SAI for now. No codes but readiness is still screwy. I read that to pass readiness MSLUB MSLBAS might be a better route for my pump being removed? Any chance of getting these addresses? If im on the wrong track here let me know. On another post I read CLASLPE CLASLVE were plug and pump plug settings. What would be my best route? tia
