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

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?

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).
