My Summer Car – ECU – The given key was not present in the dictionary

Installing the Donnertech ECU modification for My Summer Car is simple, just copy the files from the downloaded package from the mod and put them in the appropriate folder, but the problem appears when the console displays the error “The given key was not present in the dictionary” – like this to fix?

Well, to fix this you would need to know some programming skills, and if you are viewing this article, you don’t have any knowledge of programming. So you can’t fix it, you can only ask the mod creator to update the ECU to the latest version of the game.
