Hallo,
i have created a tool for old Bosch Motronic binary files.
I think it works with the eprom style ones.
The tool searches the jumptable (map address table) and creates an XDF file.
I have tested with 10 files.
Problems:
BMW M50B25TU 0261200413 1267357623 -> jumptable with holes in it, so the XDF is not completely right.
Opel Vectra B X25XE M2.8.3 -> 128kB file with two different sections, so only the first one is read.
The other 8 ones are right.
See the picture.
All maps in the jumptable create a table. Named by y and x axes, table size.
Parallel maps are marked with #
Maps without data change are marked with ( )
Possible rpm, rL and temperature in the axis would be scaled.
If there is an offset x8000 between the jumptable and the real address, it would be found.
If the map table is not ascending, it would be sorted for the map searching.
If there are double (or more of the same) jumpadresses in the jumptable, only one would be used.
If someone will test it, load up a file here. I will check it.
Note: only old Bosch Motronic files which was stored in a EPROM. I think till around 1995?
The xdf contains maps - not what the maps do.

This is the way. I started scripting after updating the 413 spreadsheets/identifications.
Are you going to open source? I recommend GitHub, it is where I have been puttiny my contributions... (Hmm I should export my Google sheets and keep a copy on GitHub too)

No one is interested?
Attached an example.
Rename the extension of the files.

Re: STA_XDFGenerator Tool, for old Bosch Motronic EPROM
There are not a lot of people still using the OEM dme. A lot just go aftermarket now.
I am interested.
Not sure what you mean by a hole in the index of tables. There are multiple types of data tables the need to be handled accordingly. The work I am continuing has them all defined.
