I bright a car with lots of issue , the main one been it was remapped in a map and possible on another map with fault codes and egr deleted .
I’ve downloaded the original manufacture stock ecu file from ecubin and would like to write this to my car .
I have Kess v2 clone which works very well at ready my car and writing back to it .
I’m just unable to write the original ecu file , I get Generic error
Do I need to change the files format to some kind that kess can see and write ?
Any help would be greatly appreciated
