@mophk If you have a 551G ECU you can easily flash the 551M file. If you look through the Forum you will find the already hacked one.

I need to keep the immo on. 551m does not do any good for me.

You can always upgrade to K-box, only small changes needed like maf, throttle and componentes delete.

as far as I know, the 551m file on the repo from Nyet does not work. the RPM isnt stable either. I have not tested this myslef yet, but someone tried the premade file from nyet and it did not work.

No clue what you are referring to.

It isn't as if ME7.1 is a mystery. Any such problems should be trivial to find and fix.

Especially since I'm running that file (or a variant of it for larger turbos).

Would you be able to post the working one? I'm currently without a test car but a confirmed working file vs the repo file would make my life easier. don't get me wrong, I saw few times that you had problems with mixed up files. or maybe give a count of changes done for the 5120 on your file?

once i have my car ill be able to troubleshoot it a bit more but I just wanted to make sure, the code is correct

Hi,
Before 5120 hack, i installed 3bar sensor, set DSLGRAD/DSLOFS and everything was ok, done about 1000km with no issues and up to 1,5perc fuel trims.
After 5120 hack, i have pulsing rpm, no torque at low rpm. Throtlle is closing, when rpm drops. Noticed, that fho_w (AltitudeCorrectionFactor) 0,48-0,49, while with no-5120hack file fho_w about 0,99-1,01. This is may be problem?

Sounds like someone forgot to change the ambient pressure sensor scaling.

Thanks for reply. I followed every step by Bische's project text file in first post(at first, tried with S4Wiki list, but it's not full), and in 30+pages didint noticed (maybe missed) additional info. Maybe you are talking about KFDPLGU/KFPLGUB?

No,hes talking about DSUGRAD and ofs... it is prolly reading ~500 mbar or so which drives the correction factor, if you did the hack according to text file you cant miss it.

A quick question
Has anyone had experience with 06A906032HF file? Its a tip copy of popular HJ file which im done a few times
Those HF which im usually used for a dsg conversion and now its time for 5120 but the engine stalls after 1 sec
Its not immo issue, works well wo 5120
Wdkba is always 0 (dk soll too, i didnt remember its acronym)
Asm changes applied as usually, checked it twice with ida
Ill post logs later but maybe anyone already been in that case
Thx in advance

Stall after 1 sec? prolly dumb idea but that sounds awfully like checksums or some checking kill command if values/logs check out, recently on one file(code mods etc.) i had bad checksums which me7sum didnt fix, winols fixed it. What do you sum with?

edit: Didnt read the DK issue part, still worth a check tho

Thanks. Yes, my car shows 0,5bar while not running/at idle. I thought it's normal (because of divided DSLGRAD/OFS).
So now i should get 1,0bar ambiente pressure?
