hj is immo 2 and hf is immo 3. hf is a awp north american file
immo is switched off in eeprom
no dtcs related to immo stored
no injector cutoff condition
works well without 5120

Finally i got my first car running on 5120hack  Cheesy
Problem was stupid - after 1013 division correction, i didin't saved file.
I made few kilometers and car runs like before 5120 hack, no fault codes, fuel trims in 1perc range.
But where is one open question about KFDPLGU/KFPLGUB:

BTW, I think I got my 1.8T running with 5120 hack. I used BOSCH 0281006059 (03K906051) sensor. Done some limited testing already and so far looks good!
There is a couple of 1.8T 5120 xdfs floating around but none of them covered the issue I was seeing; my throttle plate was not opening to 100% on WOT.
Turns out there is a map called KFPLGUB which is used instead of ambient pressure for calculating pressure ratio across the throttle plate (used in throttle maps) if CWPLGU = 0.
Apparently on most cars CWPLGU = 1, hence this map is not mentioned in the 5120 hack threads, but on mine this was set to 0.
I think the solution is to either divide both the axis and the table by 2 or change  CWPLGU to 1. I've done both just to be safe and now the throttle behaves correctly.

Unfortunately I cannot upload the xdf as the forum tells me that the site storage is full! If you'd like to have a look send me a PM.

I devided in my file KFDPLGU/KFPLGUB axis/map like BoobieTrap reccomends. Everything looks good at the moment. Should i leave it devided, or back to stock. P.S. Set CWPLGU to 1 in my opinion bad idea, because KFVPDKSD/E maps depends on it

Update.
5120 hack works great. Up to now, i was running with divided by 2 KFDPLGU/KFPLGUB maps and pressure axis; and today decided to try stock values.
And it's terrible - throttle plate angle max 50percent.
I think there will be useful information. Maybe worth to add this at S4wiki

P.S. You can download my file with 5120hack here: http://nefariousmotorsports.com/forum/index.php?topic=20105.msg149516#msg149516

if someone needs it

-> 0281002316
-> 0281006059/02810060
-> 0281002401

Just wanted to say thanks for this.  Confirmed my numbers on 0 281 002 401, couldn't find it by searching for some reason though so I figured I'd post

Hi,
I've read through the whole thread multiple times and tried to set the 5120 hack up for my AUM on GT2871R Turbo.
Currently running 1,8 bar (2800 bar absolute) in open loop at 92% N75, so far absolutely fine at around 400hp.

I'm using a 3 bar 0281002976 bosch sensor, part number 038906051C.

But when running 5120 hack, I get a strange reading in my logs.
The max value of boost is just 1090 mbar.
Multiplied by 2 it is 2180mbar - but I'm running 2800mbar actually..? I expected it to be 1400mbar to match my actual boost.

Can anyone take a look at my file? May I've overseen something?
Why do I get wrong log values?  Huh
File attached is simplified a bit.
Thanks in advance.

Yes, you could do that, hope you're not on k03's still though, they won't be too happy with you if you use the 5120 as intended! Grab the xdf from nyet's post and get to it. http://nefariousmotorsports.com/forum/index.php?topic=3027.msg29815#msg29815

Alternatively, grab one of his base files and then copy over your stage 2 settings. Probably the easier route imho.

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

where you ever able to solve this? tried 5120 on 032hj and got the same result.
