I believe what you are referring to are trim codes, like the c-15 CAT uses trim codes not files. The only cat engines that have trim files are the engines with a HEUI system. On the c-15 you can change the codes using cat ET. There might be someone that knows a little more about this, so this is just from my experiences.
