Opel delco MT35 can't write.

[Bmwpower530]

Hello guys. I Read Opel Astra with Delco MT35 ecu using Kess, but can't write file back. Always geting same "Incopatible file size" error. Is it worth to putt hope in this tool trying software versions and other thinks . Or i have to get other tool to finish what i started.

Man, maybe it's better that u can't write it with kess... i was fighting with same mt35e for a long time and kess bricked few ecus. Be careful if u don't have 29BL802CB programmer.

I try to write with 2.70. I will try v 2.23 like you.

This car Opel 1.6 CNG?

If yes, then I also could not write it with the original Kess..

Did you try writing it with k.suite 2,23 as suggested above?
EDIT:
Try writing with K.Suite 2.23 and make sure the voltage doesn't drop below 14v, maybe this will help

I always have 14v on read/write. Yes i'll try v2.23. I cant even write back ori file that i read,its like software stuck on this error when i want write, i can choose file 512kb from vw, 2048kb file from my bmw, same result. Its like its ready to give that error.
