Hi everyone,

I’m working on my VW Caddy 1.6 BSE and I’m looking for .XDF files to help me move forward.

To be clear: I am NOT looking for a ready-to-use tuned file. My goal is to study the Siemens logic, correctly identify the maps, and build my own XDF/Mappack so I can tune the car myself. I want to understand how the torque model and injection timing interact in this ECU.

What I’ve done so far:
I have successfully read the flash via OBD and spent quite a bit of time in TunerPro and a Hex editor trying to manually define the maps. I found a potential area for the Driver's Wish (normalized to 8192 / 2000 hex), but I’m struggling to find the Torque Monitoring and Lambda maps. Most of what I’ve found so far doesn’t look like the expected torque response curves, and I’m hitting a wall with axis identification.

ECU Information:

VAG Number: 06A906033HJ

Software Version: 1035

System: Siemens Simos 7.1

Engine Code: BSE (1.6L MPI)

If anyone has a definition file for this specific SW version or a similar one (like 1034 or 1036 from the same HJ/EF family) that could serve as a reference, I would greatly appreciate it. I've attached my original bin file.

I’m eager to learn and would appreciate any guidance on the map structure for this Simos 7.1.

Thanks in advance!
