Hello,


Can someone please make xdf for this ECU?


Bosch number: 0261200185


Here is bin file:

Lookup table seems to be found at 0x6400, no offset, MSB first, so first table founds at 0x673E, next 0x6744 and so on...

Biggest tables are: (Header start address, descriptors, axis size and table data start address)

687C 3A x 42 16x4 6894
68D4 3A x 42 12x12 68F0
6A92 3A x 42 12x12 6AAE
6D2E 3A x 42 12x12 6D4A
6DDA 3A x 42 12x12 6DF6
6F66 3A x 36 12x7 6F7D
7013 3A x 42 12x12 702F
70BF 3A x 42 12x12 70DB
71BD 3A x 42 12x12 71D9
7269 3A x 42 12x12 7285

I think 3A = RPM and 42 = Load.

No idea what those tables are, but i think some of those are main ignition and fuel tables. You must check.

For example:

6894 - Fuel WOT
68F0 - Fuel PT
6D4A - Ignition PT
6E98 - Ignition WOT
6F7D - Dwell angle

You can search for similar maps.

If you're familiar with TunerPro, you can create an XDF from scratch by defining parameters based on the BIN file. This requires knowledge of the ECU's memory structure and the specific parameters you want to tune.
