I'm trying to find out where ESKONF is in my BIN but I don't know how to find it. I am looking at a stock 4Z7907551R ME7.1.1 BEL 2.7T bin. I've read through the Emissions delete and setting readiness thread but it all appears to apply to other ECUs. I've checked the addresses mentioned in that thread but I don't see anything similar to it.

I guess, also moving forward after finding where ESKONF is, I'll need to figure out which bits are what(which order are they in)? How can I do this?

TIA,
Sean

Disassembly is really the only way to find the correct bits. Upload your file and I'm sure some people will take a look for you.

Attached is the file. Code disassembly seems awfully intimidating to a mechanical engineer but I'm definitely willing to look into it.

Ah, a fellow mechie. I have yet to delve into IDA. Figure I'll get my car tuned 100% to my liking before trying anything.

I believe ESKONF is located @10C86. Maybe someone else will chime in here to be sure.

Thanks, if that's the case.

It looks like:

               From        To
0x10C86: 00            C0
0x10C87: F0            FF        (Examples I've seen are F3 -> FF)

For SLS & SLV(if in same location, relatively):

0x10C85: (bits 4 and 5 to 1 instead of 0)
0x10C87: (bits 4 and 5 to 1 instead of 0, if FF didn't do that)

For the last two, I'll need to brush up on my hex to dec as it's been a minute since I've looked at their four bit representations. This is what I could see while on my lunch break.

need a little help...

I've narrowed down where the ESKONF is in the 551R box (I think so anyway), but am having a hard time making sure it's the right one.

The string which could be the ESKONF seem to repeat itself with one slight change.

Can anyone help/confirm where the proper Byte 0 is?

Thanks!

Based on this post, I think ESKONF is at 10C86 (since it's after the 00 0D sequence):

0x10C86: 00            C0
0x10C87: F0            FF        (Examples I've seen are F3 -> FF)

0x10C87: F0      to     ??
Can you post your results thanks
F0 = 1111 0000
F3 = 1111 0011
FC = 1111 1100
FF =  1111 1111
F6 = 1111 0110

Fomr the S4 wiki
ESKONF[5] (0x10C7A) - set to 0xC0 (set bits 6 and 7)
ESKONF[6] (0x10C7B) - set from 0xF3 to 0xFF (M-box) (set bits 2 and 3)

you might wish to CHECK
CLRHK is also 0x48 -> 0x49
or set to 0x05
BIT 1 and 4 must be set

Hope this helps. the file has what I use to set readiness, it has never not worked for me.

I also exported a csv with map info for every map I change on an a6/allroad for my stage2/catless/readiness needs.

Sorry for bumping this old thread with my noob question, but for what stands "II", "ZAS" and "LUES"? I can't find them in the wiki.

Sorry for digging up an old thread but I've been looking to try disable DTC's for N112/SLV in a 551N bin. I tried a flash with the only change being byte 10C8A from CC to FC per your table, but it still threw a code for N112. I then tried the same thing for the next 13 byte block starting at 10C93 (which is identical apart from byte 2), only changing 10C97 from CC to FC. This time there was no DTC for N112.

So based on my experience at least, ESKONF in 551N starts at 10C93. I will have a go at updating the definition file and sharing.
