Maybe your copy of ida is too old? 6.6 is OK. load file -> stock.bin -> as binary file. processor type = powerpc big endian [PPC] -> OK Do you want to change processor type to PPC? -> Yes Disassembly memory organization -> OK (change when you figure more out later) Choose the device name -> mpc5xx ...

This base read with RPM 8160 .I tested in XDF.

You tested in xdf or in a car?

Sorry, i´m no Bosch expert, i can´t help you at your Tipo.

Here´s a solution for the checksum

Don´t hassle with integrating the checksum, its only possible after disassembling the code with IDApro and i think we aren´t at that point currently.

Building an xdf is all hard hand-work. Simply type in all maps, scalars, axis descriptors etc.

Hi. The memory of the first post base.bin, is equal to the corsa 1.8 16v Simtec 71 or 90 with checksun 857F , in some countries can use the same memory with ECU call Simtec 90, is the same memory of vectra 1.8 16v, but in vectra has changes that you guys can compare with the memories attached. I be...

Do we know what exact processor is used in that ecu and what exact flash?

Having a short look at your file, it turns out its pretty much the same structure as Siemens MS43 and MS42 :mrgreen: This is what the guys at Siemens MS41 are using to find the correlation, but either i´m not clever enough to work it out at MS43 or its just not working at newer ecus. Maybe you guys...

I´ve made a bloody mistake, i opened the ols file in a demo version of winols and all changes i made the last 2 hours are gone, because i can´t export the file...

Here´s the maplist from the file in case i really can´t force winols to save it.

I´ve made some good progress and would like to contribute what i found so far ;) I think i found the MAF table Its located at 0x15A8 and its 16x16 (16bit). The x axis has no description and the y-axis has 4 possible descriptions which are hard to decide. Option 1 starts at 0x1071 1x16 (8bit), Option...

Having a short look at your file, it turns out its pretty much the same structure as Siemens MS43 and MS42 :mrgreen: The axis definitions are separated in the first part of that file and are pretty easy to find. However, the correlation to the maps isn´t easy and maybe only possible by disassembling...
