Astra Mk2 GTE 16v have Motronic M2.5 (ECU label 0 261 200 185)
with eprom (Eprom label 1267355632 and Eprom type 27c256).
Some of the chip-tuners have changed the contents of the eprom and by doing that they tuned the car.

So, does anybody have eprom like that?
Does anybody have *.bin file (which is the eprom contents in the file) of eprom like that?
Where can I download that?

Thanks in advance

PS: Original eprom file (*.bin) can be found at
