HI all thanks for taking the time to read this. I'm having serious problems with reading and writing my ecu. I managed to read file with galletto but won't let me write it. Any ideas on where I can go from here? I've tried mpps and the only listing they have is for astra h with edc16 ecu. I've been thinking about buying kess V2 master but after lots of reading on various gm sites figured that don't work neither.
Really appreciate any input.
Thanks again Martin
