I try to read Astra g 1.7 Edc15m with kwp2000 but it give me message "invalid key"...
How to fix that so i can read ecu propertly?

Pretty darn sure most tools these are write only. Frontera EDC15M certainly is.

Time to use a soldering iron perhaps.

You have to desolder chips and use external programmer. None tools(MPPS carlist is read/write) cannot read that ecu via OBD.....

BUT if you can get ecu ID from ecu, then you can search .ori and remap that and write via OBD......
