Looking for the following maps in my file as I swapped injectors and realized my XDF didn't have everything I needed. 2000 Audi A4 1.8t ATW
KVB - consumption constant
TVUB - injector offset
TEMIN - minimum injector pulse
I'd also like to learn how to find maps on my own instead of always having to ask, the tools I could find (maplocator-ui and me7romtool) didn't seem to have the maps I needed

KVB - 0x1A256 TVUB - 0x11DF2 TEMIN - 0x11CC6 TEMINVA - 0x11CC8 I'd also like to learn how to find maps on my own instead of always having to ask, the tools I could find (maplocator-ui and me7romtool) didn't seem to have the maps I needed
There are no universal tools . But it's very easy. Just 10-15 years of experience and you will not have any difficulty to find maps locations. |

Thank you! Could you also let me know the factors for each map, and the axis locations? My TVUB looks like it should have a factor of 0.0032 following the .ecu file from VisualME7Logger, but it appears in the wrong direction if I put in that address (highest number furthest to the right), and the values don't make much sense (ranging between 4 and 6 ms). I also can't get the axis labels to line up with anything meaningful anywhere close to the 0x11DF2, I tried offsetting it similarly to how it is in an M box file since I can't find a TVUB that makes sense anywhere else 0x11DDC seems to have much more reasonable values, and the axis follows 8-10-12-14-16, could this possibly be correct? There are no universal tools . But it's very easy.
Just 10-15 years of experience and you will not have any difficulty to find maps locations.
Do you have any pointers on where to start? I'm taking a course on assembly and stuff like that currently which I understand helps with finding maps in combination with the FR |

Also, that location for KVB doesn't make sense to me, in my bin it's just 00, do I have something set up wrong?

The above locations correspond to firmware version ..018P_0008_352802 Your version is ..018P_0006_352750. The map locations are shown in the picture. KVB (8-bit) factor=3,046875 Other maps are 16-bit factor = 0,0032 Version 0008 is update for version 0006. |

Yeah, 058 block with the small port head from the AWM in the later A4s/Passats ATW is ME7.5 NB
I never knew if it was ME7.1 or ME7.5, what's the difference? I always thought ME7.5 meant it had a wideband like later 1.8Ts and ME7.1 had a narrowband like the B5 S4, but I thought it weird that ESKONF is setup as ME7.5 (referencing S4Wiki) |

from what I have just read it has the AEB bottom so I imagine 20mm axles and small AWM head without vvt but still DBW. Maybe you can update to AWT like mine wideband and vvt. I too thought narrow band me7.1

Knowledge is not the same as guesswork.
As an example, the serien variants of the ECU me7.5 for the period MY 1998...2001.
Two branches are clearly visible - with LSF(narrow band) and with LSU (wide band).

In the interest of not clogging the forum with even more topics asking for maps, could you let me know the location of the following?
CDLDP
CDTES
CLATEVE
CLALDPE
I'm currently running without the EVAP system connected (N80 remains plugged in) and would like to rip out the LDP from my engine bay at some point, but I keep getting P0441 due to it. It's my understanding that these maps will prevent issues from the missing hardware when I zero them out.

CDLDP - 0x181a2 CLALDPE - 0x14CA7 You MUST restore the EVAP system or you will lose the STFT and LTFT functions of the ECU. This is the wrong way. That is why you do not need the addresses CDTES and CLATEVE. You should only disable the diagnostics of the LDP EVAP parts, not the whole system functionality. |

I should have been more specific, I have the EVAP system in place and my N80 plugged in, simply that the LDP is unhappy and throwing codes. My fuel trims seem to be working just fine |

RTFM aka FR for ME7.5 If the P0441 error is present in the ECU memory, the LR adaptation is frozen and the LTFT/STFT values do not change (freeze) until this error is cleared. After clearing, the LR adaptation is enabled and works until the TEV error appears again. |
