This is what happen after engine is after 80degree and trims begin to works. I attached a log but without modified "P" variables in file.ecu for me7logger.
The baddest thing is after i push acceleration and i left it for engine come back to idle.
I tried many dslgrade and dlsofs calculation, but all are the same.
I tried with fkkvs all 0 , and with my fkkvs from my daily file. The same thing.
With new version of Justin file , error from vcds "pressure drop between manifold and throttle' not appear again , and in group 008 , actual preassure was changed with "breake boost" .

Hi Justin. I use your file now with some mofiication for my car. It works ok with some issues and one problem!
Do you have the same issue as mine with camshaft angle when it must be changed by KFNWSE? Mine change after 5750rpm and it must be changed at 5000rpm.
The problem is from time to time when i try to make a log from 1000rpm when the boost up over 0,8 bar(approximatly) something cut and the car don;t make boost and feel like the same it is to rpm limit.
I attache the good log("log r64 3rd.csv") and KFNWSE map (WWLE is the same). The log wth cutting problem is "bad log.csv"
CDNWS is 3 and in eskonf vvt is active!
Can be in the asm code for 5120 hack an error or i must change other thing in some tables?
Thanks.

Why is wgdc still increasing when req goes over actual boost?

I am not sure you understand how the PID works if this wasn't immediately obvious

It is first log and i will adjust it in time. te problem was camshaft not change at 5000-5200 rpm conform with kfnw....

Same file only TVUB different had camshaft changed ok.
In that file too req is over actual, so i think is not a cause for my problem. Please Nyet maybe you can give me another solution for this.
I will keep actual boost and wgdc as it is maybe will increase a little to make 1.9 bar and will decrease req boost from ldr and iop.

Hi again.
In 5120 txt file with modifications you said
"KFLDRQ0(LDRQ0DY)- Divide axis by 2(Multiply by 2)
KFLDRQ1(LDRQ1DY)- Divide axis by 2(Multiply by 2)
ZDSU      - Sqrt and multiply by 2"

I found in file for these 2 maps only axis devided by 2 , but values not multiplied by 2. Does it must multiply them or not? Maybe in understood wrong your specification from upstaires.
ZDSU is not calculated. In a stock file it is 3, in justin file it is 3 too. If we apply the (sqrt(3))*2 result is 3.4641 . Did it must modified for 5120 hack or not?

Thanks.

I hoped with last night modification for some tables and with cat cleaning complete modification in my 5120 hacked file*start from justinvw file ) , resolve the problem, but nothing.
I modified to 5120 file (justin file) :
  KFMRESNL because i suspected it and i made all 0.
  CLRSHK made 5 was 0

I wrote the file and start the car. First 5 minutes car works ok at idle. After trims begin to work (STFT specially) after 2 minutes coolant temp was 70-75 degree and there idle goes crazy again. I made a log for this and I made a log for 90 degree too , where I arrived with car at home after 5 km running and stop it at idle. In 30 seconds idle goes crazy again at 90 degree coolant temp.
I checked all maps.scalars witch are modified in 5120 file from stock file and and all looks ok.
What is strange I don’t find any byte or something who tell me have other modification exclude maps, like asm changes.
With stock file modified with 4 bar map sensor car stay stable at idle with all maps/scalars same like in 5120 file only was need axis or mapss values divided or multiplied with/by 2.
Other thing who i saw in VCDS in block 8 absolute pressure with engine start is 50mbar with 5120hack file but with stock file (with the same map sensor like 5120 file) i saw 230mbar.
Some suggestion please? I don't know what happen and where is the problem.

Hi All,

Just wanted to share a stock file with a few more changes made, I got the file from page 1 of this thread.  I went through 5120 maps checklist.txt posted in this thread, as well as the page in nyet's wiki https://s4wiki.com/wiki/Manifold_air_pressure:Rescale_project

Changes I made:
ZDSU      - Sqrt and multiply by 2 (modified by blair)
PUEBKV      - Divide by 2 (modified by blair)
KMLTESG      - Divide by 2 (modified by blair)
KISRM      - Divide by 2 (modified by blair)
ZDSU      - Sqrt and multiply by 2 (modified by blair)

Things that may require more changes:
DSUGRAD      - Divide by 2 (DSUOFS was zero, otherwise divide by 2) (NOT FOUND) (fix)
NLDIAPU      - Divide axis by 2 (AXIS NOT DEFINED) (confirmed axis not defined) (fix)
PBKVVSTG   - Divide both axis and curve by 2 (NOT FOUND) (fix)


I hope to share a stock file with all the required scaling completed.  This is very close, just have to go through and find verify DSUGRAD, NLDIAPU, PBKVVSTG.

Don't use this without checking my work-- I'm still a noob and this may contain mistakes, it is untested!

Edit:

I think I found the following by comparing to an 8N0906018CB file and map pack:

dpupvdk: 1C82A
dsugrad: 1C83A
dsuofs: 1C83C

All of these are zero if I'm right.

pbkvvstg at 28A4E with the x-axis at 28A42.  

This is a stock file with 5120 asm and all the axes scaled correctly.  It is untested though!

Edit: I've recently gone over this file after many miles of testing and had some issues with pressure/load not behaving as I'd expect.  Car runs fine, but ps_w and pvdks_w don't follow closely (not a pid issue) and rl_w and rlsol do not behave as I expect

KVLAD 0x10D49 1 byte 0.007813 * X, value is currently 1.5626 (stock is 0.7813 so this is multiplied by 2) is correct, but was also incorrectly defined in my xdf as 0x10D48 (and also multiplied by 2)

I think 0x10D48 is actually KUMSRL (Conversion constant from mass flow to relative air filling).

Not yet, I put my Golf in hibernation for the winter before I got around to it. I'll let you know what happens when I get around to trying this, hopefully will be this summer. 

I'd feel better about this if someone else checked my work.  I'm getting better at finding maps but I'm still new to this.

Best,
Blair

I went over your file and everything looked correct, so i went ahead and modded it to my suit and flashed it to my car.
And everything looks to be working perfect. Thanks so much for the file  Grin

This file is working great on my car as well.  Tested today, can post logs if anyone is interested.
