Looking for ESKONF in my original 4B0907551G.bin that I read some time ago.

Think I found it at: 14ED9-14EE5

00 FC EF FF 3C C0 FC FF AA FA 55 55 55 from 4B0-551G
00 FC E3 FC 0C 00 C3 FF AA FA 55 55 55 from 8D0-551L


Not sure if this of any use though!

edit

Realise I removed BKV for no reason!!
basically should have copied entire 13 bytes of ESKONF from 4B0-551G to 8D0-551L.

   VCDS displays "Passed" for all readiness checks. See below for secondary O2 changes in my file.

All set to zero:
CLAHSH
CLAHSH2
CLAHSHE
CLAHSHE2
CLALSH
CLALSH2
CDHSH
CDHSHE
CDKAT
CDLASH
CDLSH
CDLSHV
CWDLSAHK

After flashing these changes, I ran the readiness checks for the O2 sensors per the Ross tech wiki.
http://wiki.ross-tech.com/wiki/index.php/Readiness_-_APB_Engine_Code "

Think that might do it....?


EDIT
Nope, missed this, from s4wiki Rear O2 ESKONF. https://s4wiki.com/wiki/Tuning
ESKONF[5] HSH2 (0x10C7A) - set to 0xC0 (set bits 6 and 7)
ESKONF[6] HSH (0x10C7B) - set from 0xF3 to 0xFF (M-box) (set bits 2 and 3)
ESKONF[6] HSH (0x10C7B) - set to 0xC3 to 0xCF (L-box) (set bits 2 and 3)

And CDLATV  to zero if 02s not setting readiness Reply #107 trichard3000 http://nefariousmotorsports.com/forum/index.php?topic=615.105


& of course Check Checksums:

00 FC EF FF 3C C0 CF FF AA FA 55 55 55
https://s4wiki.com/wiki/Tuning#Rear_O2_ESKONF

Presume it's a typo, should say "ESKONF[6] HSH (0x10C7B) - set to from 0xC3 to 0xCF (L-box) (set bits 2 and 3)", as the line above it says.

Would this mean that if those bytes were NOT C3, they should NOT be changed to CF? Or just... change to CF?
