Reverted CDLSV AND CDHSV. Set CDLATV back to original(1). Found post from masterj that conflicts with the wiki page as it states it for rear o2's (post-cat),
"
CDLATP => SWITCH: Pre-CAT O2 Sensor Aging Diagnosis (Two Point Control)
CDLATV => SWITCH: Pre-CAT O2 Sensor Aging Diagnosis (Mixture Test)
"
Since all my current settings leave me with only Bit 5:Oxygen Sensors not setting, I looked up the function of each error that is checked.
Bit 5 : Oxygen Sensors
Init bit : B_cdlsv
Errors checked : E_lsv
E_lsv2
E_lsh
E_lsh2
E_latv
E_latv2
E_lash
E_lash2
E_latp
E_latp2
Codeword : CDLSV
For CDLSV: Code word probe diagnostic before cat in the OBDII-Mode. It's currently enabled as a
PRE-CAT
function.
For CDLSH: Code word probe diagnostic behind cat in the OBDII-Mode (inverse: Europe mode): It's currently disabled as a
POST-CAT
function.
For CDLATV: Codewort Lambdasondenalterungsdiagnose (tv) im OBDII-Mode (invers: Europa-Mode): It's currently enabled as a
PRE-CAT
function.
For CDLASH: Codewort Lambdasondenalterungsdiagnose (SHK) im OBDII-Mode (invers: Europa-Mode): In FK diagram, CDLASH is under "FSWHK: Sharing feature of the Schwingungspr¨assessment behind CAT": It's currently disabled as a
POST-CAT
function.
For CDLATP: Codewort Lambdasondenalterungsdiagnose (TP) im OBDII-Mode (invers: Europa-Mode): It's currently enabled as a
PRE-CAT
function.
Thought process pointing in the right direction? I've crossed referenced every variable that I've changed in the current file and the changes are substantiated by either FK or the forum members. Possibly notable, I couldn't conclude on is from the wiki, CLRSHK. In the FK, it just states setting bit 0 to 1 in order to disable post-catalyst control however the wiki has bits 1 and potentially 2 set.
I'm guessing that I'm missing a variable that needs to be modified?

Hi!
I just made an wideband conversion last week, on my car. It was an APP engine (ME7.5.1), and I used an LP ECU cross-flashed with HP map.
Same issue here. No LTFT after the conversion.
On this weekend I will try to fix this.

Ran through the setting readiness thread and found what I was missing! Masterj's comment about CDLSH needing to be active for the B1S1 tests to pass. Figured I'd respond to this thread as a conclusion. Fuel trims look fantastic and everything sets finally.
My edits to the file are as follows:
VVT:
• CDNWS at 181AF and changed to 0
• KFNWSE at 173FB whole table set to 18
• ESKONF at 10BED: AA FF 00 30 FF FB 3C changed to AA FF 00 30 FF FB 3F
• Copied KFZW to KFZW2 and KFZWOP to KFZWOP2
SAI:
• MSLUB @ 0’S
• MSLBAS = 0
EGT:
• CDATR = 0
• CDATS = 0
• CATR = 0
CAT + O2:
• CDKAT = 0
• CWKONABG = 0
• USMIN = -1
• TANHKMMN = -273
• THSHA = 0
• TRSE = 0
• ESKONF, BYTE 3 = 30 => F0
• CWKONLS = 1
• CLRSHK = 11 (HEX)
• CDHSH = 0
• CDHSHE = 0
• CWDLSAHK = 0
• CDLASH = 0
• CLRSKA = 0
• KFTVSAKAT = 0
• ZATMIKML = 1’S
• ZATMIKKML= 1’S
• TABGMEX= FF
• ZATMKML = 1
• ZATMKKML = 1
• TKATMOE = 0
• TKATW = F
• CWLAMBTS.2 = 1 (4 dec)
• DTBTS = 0
• FKHABMN = 0
