This tool do this calc:

but I don't have. I have license to change km in eprom without chksum

But there are huge changes in this eep. did you only change the km or something more? As you can easily see the km changes, but there are some other huge blocks changed. I can do the crc, no problem, but these big differences between the two datasets are a little bit "scary".
