Hello to everyone. I have a strange problem with a Corsa C ecu. I read the original file from the ecu, but when I wanted to open it with Winols I took this message: "When reading the eprom probably an address line was defect...". I read again with the same result...I found another original file from the same type exactly with but I have again this message.

The ecu is: Marelli MJD6JF
Hw: MAG 01246JO01d
Sw: 1414X188

Thanks in advance!

Some friend told me to use Galleto for this ecu. I will give a try with bdm first to see and after I will use Galleto, I don't trust it a lot...

I read and write such ecus with Kess v2 and Ktag on the bench without any problem. But wasn't necessary to open file with winols until recently.

i used kess v2 to read it and when i loaded into winols for editing I got same message...I was suspicious and didnt wanna write it but instead I read again with FGtech Galleto v54 and got a read that was same in size but contained more changes in first part of file...like kess read was missing a big part of file...when i loaded it into winols I didnt get any message about beeing defect, then i edited , let winols correct checksums and write with galleto no problems

Best Regards

Hi, first i readed this ECU with mpps, and it gave me 448 KB. I open in winols but without error and with OK checksum. Read 45 min by OBD. But if you write this file in OBD the ECU will dead. second I read with FGtech by BDM and the file was 449 KB. When I opened it there was NO CHECKSUM. But don't worry. FGTech correct CKS success for this ECU.

Here are files readed by FGTech BDM (ORI + MapPack + Eeprom)
