Hello

I understand that removing the egt probe from k04-023 turbocharger will cause mixture enrichment and probably MIL.
Is there a way to remove it without affecting car work behavior from SW side?

Thank you.

i believe you need to set CATR = 0

S4wiki

http://s4wiki.com/wiki/Tuning#EGT

With a k034-023 on a stock manifold I would want to run the EGT in place.

You could run 032HJ SW non EGT and utilse the egt model

But as stated Catr needs to be set to 0 otherwise you get constant protection fuelling ( ie 0.75 all the time) Setting it 0 gives normal lambda fuelling as found in the Hn or Hj.

I have asked for s4wiki to be updated

Ahh...ok, I guess that negates the need to FF TABGSS?

TABGSS was being FF'ed because when the sensor is unplugged it gives a max reading causing intervention.

Yes that would make sense, I never tried FF tabgss as when I got the issue I had a look through FR and stumbled on CATR and that worked so left it at that. As far as I can tell just setting Catr to 0 switches the EGT off com

It works well if you want to run a BAM flash on a 032hn or hj ecu and don't obviously have EGT. In my case it's been hybrid k03's as the flash already has s3 maf scaling s3 fuelling etc etc

CATR shuts down ATR I'm guessing. So CDATR and CDATS are still required to shut down diagnosis?

I'm not at my computer and have never cared for EGT delete, otherwise I would just look myself.

CATR, CDATR and CDATS did the job.

Thanks guys  :)

I didn't see this. Can somebody clarify what, exactly, should be added to the wiki?

In particular, i didn't modify CATR and i dont see lambda problems (with EGTs installed)... unless im missing something... is it only needed if you remove EGT sensors entirely?

Thanks.

Yes to completely remove EgT and not set off egt protection fuelling CATR needs to be set to 0 . If you remove the EGT but leave at 1 you'll get a constant .75

Thanks. s4wiki updated.

and after removing EGT
not need CWLAMBTS  set 4 ?
because example :AUQ 180PS original file "4"
BTS fueling working fine CWLAMBTS  0 ?

If you remove EGT on a K04 car and only disable the EGT codewords you will end up 100% with molten engine because the car will never go richer than 0.9 lambda.

 >:(
ok and CWLAMBTS  set 4 correct same as 180ps car ?
and modification
KFFDLBTS
KFLBTS
KFDLBTS

need anyother map?

Yes needs more work. Read ATR, ATM, LAMBTS and LAMFAW modules. You can also compare the files from non egt versions and see the differences.

ATR only need CATR set 0 no other thing
LAMBTS i think fine
ok,
i check other 2 module

thanks

LAMBTS is disabled via a different mechanism on K04 factory tunes.
Make sure you test and fix this ...

and need any other module checking ?
 ATR, ATM, LAMBTS and LAMFAW

Could you give us some hints where should we look?

????????

bump this thread
same problem here  :-\

TABGBTS is the threshold to turn on BTS fueling and FBSTABGM is the multiplier that factors in bts fueling based on the egt model or actual egt. I think that the axis values of temperature on fbstabgm is higher on those K04s so its mostly inactive. You can use look at a non egt sensor file to see the difference. Maybe thats what he was getting at...?

No.

prj say again big nothing :)

yep
and this night i spent by comparing, ida tracing, changing, redbulling etc
but still has poor results like a directly switch to driver requested lamfa map and dont know about bts

TKATBTS
Temperature threshold for component protection near the catalytic converter
This value is maxed at 1229 in a tt225 wideband file im looking at. But in a 180 hp file it is at 100 degrees C.
I checked ATR ATM and lambts and thats all i could find that could disable the egt model from functioning. Is that it?

where can i find these in 1.8t bam 8n0906018h files, are these the same adresses as mentioned in S4 wiki?
CDATR (0x18196), CDATS (0x18197), CATR (0x192CA)

CDATR and CDATS are in that location on a 018bb i have. The CATR for my file is at 0x19406.

CATR stock value: 5
CDATR and CDATS stock value: 1
Your catr may be at a different address or not but the stock value will help you know you found the right spot.

thx, found CATR on 0x1937A  (8n0906018h 0004)
CDATR seems to be at 0x18196 and CDATS at 0x18197 as they are in your file and on s4 wiki

btw found CATR bij searching the hex sequence starting from 0x192CA in a 8d0907551m file
this sequence found it ( 01 05 05 32 4B 64 7D 96 5B 76 ) at 0x1937a in the 018h file, stock value is 1

 is it TKATBTS??

Instead of posting on forum go and test...

It depends on the file, but on some you will have a lot of grief getting BTS to kick in...
And it's not only the temperature thresholds.
