The way I read the FR agrees with masterj. b_sbbhk is required to set z_lvs. And the only way to set b_sbbhk is by checking rear o2 sensor. There's no CD to bypass and automatically set b_sbbhk.
I think for this purpose they have compile-time constant (for example SY_LSHK).
That's why it is not so easy to set readiness via code words.

Then why not change your jmpr cc_NZ to jmpr cc_UC where it checks for b_sbbhk in DLSU. Should be a one byte change. Or change it to check #1 instead if b_sbbhk.
masterj did you happen to find these lines of code?

I've changed the bclr b_sbbhk to bset now. From what I can see in FR and code there is no problem having b_sbbhk set permanently when rear O2 are completely coded out.

Not sure if its mentioned in this topic further on already but for the EGT you also need to disable CATR. I my case it was pig rich at idle and low rpm, it wasnt using lambda and big oscilations at idle sometimes. Also the boost was limited so I guess it turned into limp mode. I did not got any DTC because I disabled everything already.

Thanks for the info, got my wideband ecu running on S3 APY! Grin

Guys, please help me to find CLRSKA in 4B0906018DC. It is different from 06A906032HN in ida and I am unable to find it.

I am attaching ida screenshots from both files and my suspect address of CLRSKA. Also bin is attached


This looks really similar to a PLC Language. Edit, searched and found an answer.

So Im doing rear o2 delete on 551r and im trying to make sense of the wiki's instructions.
at first it states:
CLRHK (0x11A87) - Code word for Lambda - Control post cat on/off: set to 5 (00000101b)[58] or set to 73 (0x49/01001001b)? (original value 72 0x48/01001000b)
Wideband vehicles use CLRSHK. In these the default value is typically 16. Set bit 0 to disable (Increment value shown by 1)

LRSHK (to disable postcat o2 correction):
CLRSHK.0 = 1
CLRSHK.1 = 1
LRSKA (to disable "cat cleaning" function):
CLRSKA.0 = 0

From what i can gather, wideband cars have clrshk and clrska. but narrowband have clrhk clrka instead. So to do a proper code out im confused whether clrhk should be set as 5 or 1 to remove rear o2 influence. Just wanna be sure because Im going to feed a wideband o2 through the post cat signal wire and I dont want to have any unwanted effects. Thanks

I wish I could answer this conclusively, but I believe if you have CLRHK, set it from 72 to 5, if you have CLRSHK, set it from 16 to 5. What is your stock values for CLRHK and CLRSHK?

BTW i just edited the wiki in the hopes it is more clear.

551r stock
CLRHK: 72
CLRKA: 3

CLRSHK doesnt exist in my 4 def files.

If you wanna add ESKONF for 551r it starts at 0x10C86   bytes 5 and 6 change from 33 and F0 to F3(byte5) and FC(Byte 6). for rear o2 removal.

AFAIK, set CLRHK to 5 and CLRKA to 0

Sorta. CA smog stations themselves are notoriously lax .. and many states have MUCH tougher inspection procedures. I'd hate to make any guarantees to anybody here..

Just came across this thread, and just want everyone to know just how the OBDII "smog" testing really works...
CA actually has the toughest OBDII standards, and the other 7 "green" states follow suit (NY, MA, CT, RI, NH, NJ, ME)
I am a RI state inspector and have helped systech (now called opus) develop the standard for the OBDII data for RI.
This system is currently in use in the 15 states that opus technologies builds state inspection machines for..

it asks your ECU a series of mode $01, $03, and $09 questions.  NOTHING is reset.
mode $01 - RPM, O2 sensor locations, current DTCs (if any), supported monitors, monitor readiness, command MIL (is it on, and does it work), and ECU address (2 digit hex code)

Mode $03 (not many vehicles support this mode) - OBDII standard (US, CARB, Euro, JPN), calibration ID, software ID
(mode $03 is more for the EPA's database)

Mode $09 - Calibration id, ecu checksum, vehicle VIN

the machine will, however go back and forth between reading DTCs, command MIL, and monitor readiness (due to a few devices that were out there to defeat inspection machines - the back and forth would make them crash)

running the basic setting tests, you can get a VW to 'correctly' (as far as the inspection machine is concerned) set all the monitors, and pass state inspection without moving the car a single inch...

as long as only 2 monitors are not set for 2001 and older vehicles, and 1 monitor not set for 2002+ vehicles, you will pass.

changing the values so it just shows a monitor as being 'not supported' is fine as well..

the machine WILL pass a vehicle that shows all the monitors as being 'not supported' - it really doesn't care..  as long as there aren't too many 'not ready', you get a sticker....

and the other sad thing is you can have a whole bunch of current DTC's as well - just as long as the CEL isn't on!  (there are vehicles that the ECU doesn't have seperate current / pending flags, so any code either current or not, all show up as current...)

Pure gold post turboneoffroad! Thanks very much for that info. I don't live anywhere that tests, but that may change in the future...

It also depends which monitors. Cat eff wont pass even if it's the only one not complete. This has been my experience. I was told by someone high up that certain monitors carry more weight than others, and it's not just the number of passed to incomplete.
