What hardware is used at that ecu? What flash? What processor? Seems like their is a different memory which contains the boot section. We would need that for a disassembly.

The flash is AM29F200AB (psop44).
I remeber that on the board there is a eprom(8pin) but i don't know which one.

No, i'm sorry. Now i'm sure that there isn't an eprom on board. Only the flash and processor can give "information"

Next step is disassembly of the flash. Unfortunally there is bootcode missing if i 'm not totally wrong. The first few Bytes hint to the reset handler usually.

Did you work on this ECU more? This forum is my only hope now haha I have a couple of tuned maps from my car but I didn't notice improvements. I am using WINOLS but I can't find what is what. Can we work on this together more? can I contact you on a different platform?
Thanks!
