Hey all, lately ive been trying to tune ahkatmn and ahkatmx since i dont run a cat. i have all 4 02 sensors hooked up and working. readiness for 02's, heated cat ect will pass obviously but ive been having trouble modifying the the ahkat values to allow the cat to pass. ive change ahkat mn to .00 and ahkatmx to .95 . maybe im doing something wrong. I do not have a 022 906 032 eg damos available so ive been going off the euro r32 or euro toureg damos floating around. ive included a tuned file with launch control here as to share with all of you and the damos ive been using. any help appriciated.

heres the damos

Sorry, didn't read the whole first post.

thanks for the bump tho. im in between thinking i either am not adjusting the values at the correct offset which i believe to be 18728 and 18729 ahkatmn and ahkatmx respectively in my bin or the values im using are too low and too high. i have use the same factor as the damos and with tuner pro i numbers that appear to make sense they are 8bit and the factor is .003906. the original values were 18728 .15 ahkatmn and 18729 .40 ahkatmx. the location in the damos matches very well in 2d in winols at least to my eyes. thanks any help is very much appricated 

here are screen shots of tuner pro and winols

Ok been busy this week. I'm gonna try to start playing with this during the week. Can anyone confirm that I'm in fact modifying the correct bits? Seeing as I can't flash this particular ecu thru obd it make the process of playing with it a bit more of a pain. I have to boot flash it everytime. For some reason mapps won't flash this ecu on the bench either although I've done like 4 other r32's over obd.

I believe you leave ahkatmn alone. But adjust the upper threshold adkatmx to the max value available in tuner pro. Also enter max value for ahkats and ahkatsb. S4wiki has good info on codeouts like that.

MX and MXT should be enough. I don't think your locations are correct, though.

I was looking at the file and comparing to  toureg file I have and I may have found another location for those bits. I'll post a screen shot tomorrow so you guy can see what I'm looking at.

AHKATMN: 0x18728
AHKATMX: 0x18729
AHKATS:   0x1872A
AHKATSB: 0x1872B

Looks like you've already been poking around in there.

Also, you should post original files. Looking inside that abortion you are running nearly blinded me!

Thank you sir. I'll try to clean up the file, I know exactly what your talking about

just messin' with you.

Ok so this evening I set ahkatmn back to stock and maxed out ahkatmx ahkats and ahkatsb. Now ahkatsb was already maxed out so I didn't have to touch that. Again everything passed but the cat and I also threw cat efficiency codes for both banks. I'm not sure where to go from here. Thanks for all the help so far guys.

have you considered logging AHKAT?

I'll log that. I assumed the measuring block in the test was ahkat I hadn't considered logging. Thanks for the guidance.

Max this too. I mentioned it in a response above. Just MX and MXT.

AHKTMXT  1872C

I haven't had a chance to test it yet.

 :-*

Ok I see what your talking about now. In my damos it's ahktmxt so when I was searching I missed it. I edit my bin and give that a shot. I'll log if for some reason that doesn't work. I really should get in a better habit of logging with something other than my VAD software and my dinosaur palm pilot... it is really small and the bluetooth is nice though.

nice right lol

Yeah I tried this yesterday, and same result no good. As far as logging goes I put a couple hours into trying nefs logger and me7 logger with no success. Just to rule out this file I'm gonna flash a stock file with the bits modified. Im also gonna study that damos a little more I must be overlooking something. Again you guy have been awesome.

i was just looking thru the values and i think ahkats should be set to stock. i will test later or this weekend and see what happens. if i have time i will work on getting a logger to work also.

Did you try this yet???

As in "leave everything in the file as original and only raise these two values?"

this weekend i will thank you

So I tried MX and MXT with all other bits stock and again threw codes and no readiness. So I'm gonna have to log and go back to the drawing board. Thanks again

100 %  sure u have the correct maps?   I'll check in IDA if you send the file

According to ddillenger they are correct. When I was searching the file I came up with the same. I will post the file later today. On my phone atm. Thank you

here is the file completely stock

has anyone considered, I don't know. Lowering...

I'm sure maniac is ready to consider anything at this point. :)

Your right ddillenger think. I'm gonna try to set ahkatmn and ahkats at minimum while setting the mx and mtx to max. Also I will have a log up in the next few days. Thank you guys

:)

For the setting of the error and cycle flags the following considerations were laid down:

1.) An individual error exists that means in one bank after the active monitoring time (TDKATAKT) has run out ahkat is larger than
the maximum limit (AHKATMX). In this case E kat and Z kat are immediately set to TRUE (individual error has high priority).
2.) An added-up error exists that means that after the active monitoring time has run out the sum of the ahkat-signals of the two
banks exceed the preselected border AHKATS. In this case the catalyst which shows a larger ahkat-signal is detected as
defective. For this purpose a lower limit (AHKATMN) is defined which may not be undershot. Furthermore the active monitoring
time of the two banks must have run out and in none of the banks no individual error may exist.
By forming the flag (B zkats) three conditions are fixed. Firstly that in one bank the time has run out, secondly that no
individual errors have occured and thirdly that the ahkat-signal of the concerned bank does not lie below AHKATMN.
3.) An error of the adding range exists that means after the active monitoring time has run out an added-up error exists if the
ahkat-signal is not larger than AHKATSB. The meaning of this being that in case of an
added-up error both catalysts will be detected as being defective if they do not differ largely in the state of their age.

I wonder why that one word is bolded, italicized, and underlined like that?

Are you alluding to adding active monitoring time. Also thank you for dropping some knowledge.

Ok so it looks like I'm just an idiot.... and mixed up my ahkats offset... so I'll test in the next 2 days and confirm. If there are no objections I'll post a stock file with this cat bypass completed after I test it.

ok heres the deal so far. i have passed bank 1 cat test, bank 2 has not failed yet. im not worried about it failing because at least in an r32 the cat test run though vag com or my vad system is too short, causing the test to turn off before it is completed. i have experienced this in stock r32's where it is necessary to drive the car for the cat to pass or fail. so once the bank 2 cat sets ill post a file. thank all you guys so much  8) 

I would say verifying what actual values/maps you used would be enough. I personally wouldn't post the file. Everyone on here is smart enough to follow directions.

ok so readiness has set!
