I think maybe carprog is your problem, it's very unreliable, post again here the file that you want edited and what mileage you need

I'm coming to that conclusion. I edited the file and I can't write it to the new or original eeprom. I tried it on another cluster with 24c02 and it reads but doesn't write, so everything indicates that the problem really is the carprog. but it always worked. before reading and writing.
