So as some of you might know, the ME7eeprom tool doesn't cover the me7.1.1 eeprom's which are generally 95160 or 5P08C3. Can someone help me understand how to change a vin in the eeprom in these ecu's? I've been stumbling through it for years and usually I'll revert to cloning if I absolutely have to but I'd like to learn the logic. I'm not very good with hex.

How do you calculate with eeprom programmer? Which programmer? I haven't found anything that works with it reliably. Ksuite doesn't read out the eeprom on certain ecu's. It's all FF's.

As far as i'm aware this tool will not calculate eeprom. The tool that will is Checksum95040.exe but that wont do larger files than 95040. 95160 and 5P08C3 don't work. I wish they did. That's the tool I use to calculate the 95040's. Matter fact, some 95160's have 00's or FF's at the second half of the prom and i've been able to cut that section off, calculate and add that section back on but I don't know enough about the correction to be able to use it any further than that on the bigger files.

But a 95160 and 5p08c3 file are bigger than a 95040. It writes FF's to the rest of the file from what I remember. I don't see how that would work.

And the checksum doesn't need corrected in the rest of the file?

Why don't you try write it to ECU?
