Im using that 551r file with great results with 4 bar vw sensor set map DSLGRAD to 875 and DSLOFS 62.50 (make sure you're using a 5120'd XDF.) I would log ambient pressure and see if your map sensor is reading properly.
I tested and solved my issue a couples posted back. There were a few more p variables i needed to double in the .ecu file for me7logger. Correctly reading the right pressure and boost levels now. Ive attached the .ecu file with values for the 551r 5120.

Please excuse my ignorance, i'm new to this, have read all 36 pages but it's going over my head at the moment. I'm still at the build stage at the moment (Audi 2.7 into a Boxster) so haven't yet tried to get my head around the software side of things. I'll be using a Zeitronix ZT-2, will I be able to use this hack with this 5 bar sensor http://www.efi-parts.co.uk/index.php?productID=268 and can it be shared between the ECU and the Zeitronix? |

If it is linear and has 0-5 v output i bet it can be scaled to work with the ecu. May take a couple tries to get it to read accurately. The 4 bar vw one will be a plug in fit to your ecu harness and wont have any guess work associated with calibrating it.

I've done hack on BAM 1.8t. I have 3 bar map sensor. Baro pressures on vcds are equal but VCDS are logged 820 mbar pressure so it is devided as I done in pressure maps.
I have another problem. I have on LDRXN flat 180 value so I should have about 1.1 bar boost. I have over boost, cause on my boost gauge I have 1.5 bar peak and this drop to about 1.4 bar and I don't have any throttle cut or anything. Whats going on?

Of course on WOT requested boost equal actual boost (1.1 bar logged) so why boost is additional 0.4 bar?

Impossible to tell w/o logs, plus there is no way of knowing if you got the hack right. |

I will do logs tommorow.
Hack I've done multiple and devide pressure maps by 1.2 to suit them to my map sensor and DSLOFS , DSLGRAD is calculated to 3 bar map and devided by 1.2 and 1013 hpa assembly points are devided by 2? Maybe they also should be devide by 1.2?

any scalar would work but iirc prj suggested 50% as it's easy and plenty.

Hi would any one be able to direct me to the location of the 1013 divisions on a 081H file please
I believe I require :
pvdk_w #1 or #2
fvpdkds #1 or #2
fho_w
frhodkr_w

Understood. I don't use VCDS for anything except logging adaptation values, but I can see how this would be valuable. I will add the changes to the M-box bins posted in this thread if somebody tells me what to mod  Thanks, and sorry for the misunderstanding. I didn't play much with the OBD communication protocol, but here's a quick hack to make VCDS display "proper" (and not halved) values with 5120 mod: Valid for M-box only!0x6A338: change 7D to FA 0x695B0, 0x69416 and 0x6B646: change 7C 84 F1 C8 to EA 00 6E A3 0x69402: change F3 FC 43 8B EA 00 BE E6 to F2 F4 84 A2 EA 00 6E A3 Now VCDS will display proper values (but likely will still max out at 2550ish - not sure, need to test this). EDIT2: Added overflow control. It's not very elegant, but should work. |

Definatly related to the ASM divisions, ask me how I know lol  I noted that in your OLS you have the asm division fvpdkds, but this should be fpvdkds. In my own 1.8t disassembly, the first occurance of #287h is going into pu_w, and the second occurance goes into fho_w. The last 3 are (I think) the correct values for the fpvdkds and fho_w divisions. Is this the mistake you made, britishturbo? Oh by the way, nice work I hope to need this hack in the near future. |

Valid for M-box only!
0x6A338:
change 7D to FA
0x695B0, 0x69416 and 0x6B646:
change 7C 84 F1 C8 to EA 00 6E A3
0x69402:
change F3 FC 43 8B EA 00 BE E6 to F2 F4 84 A2 EA 00 6E A3
Now VCDS will display proper values (but likely will still max out at 2550ish - not sure, need to test this).
EDIT2: Added overflow control. It's not very elegant, but should work. This will still max out at 2601mbar you need to change the formula. |

Here is a map pack for my software including asm divisions and seperate 5120 maps folder:
Audi A4 1.8T 4B0906018CA 0261206917 0003
Factors have not been altered in this map pack by the way, but maybe it is nice to do this after modification of the bin. There is a division of pu_w in the file, I left this one untouched for my initial test since there is no mentioning of this one in the files I've seen.. I just collected a bunch of divisions from my disassembly. ** Since my test worked, this division is now removed from the map pack.
I reworked my own file now, for test. I just dont really understand the logic applied to ZDSU. It is a time constant, why would you change this? In Bissche's file it is set to 12, in the txt file it says sqrt/multiply by 2. Now that would yield a new value of around 3.5, since the original value is 3. The FR says it is 5. I left it at 3 in my file for now, since I dont expect this constant to work against the hack.
* Did a testrun today, and everything works as expected. Awaiting 3 bar sensor for 2560+ test.
added *.ecu file with 5120 mods and original (unmodified) bin.

Tried file posted here on forum, 4B0906018CH 0261207216 360101 on my newly rebuilt AJQ engine (with wiring harness and ECU from an Euro 4 engine).
Rescaled KRKTE for my 1000cc injectors with no luck. Car won`t start. Has spark, but injectors aren`t opened at all (after emptying 2 batteries few drops of fuel are visible on manifold). With same file, but without hack and KRKTE recalibrated engine starts very easy.
Is there any version of file for 018CH with 5120 hack that works 100%?
Thank you.
