Peugeot 208 BSI Valeo

[marcolr]

Hi friends,

I need calc checksum and erase history in a Peugeot 206 BSI with 95256. I know algo for calc Km, but I don?t know how to calc Checksum.

I upload two files, one with 127024 km and other with 42512 made by me but with bad chks and no history erase.

Can someone make this for me?

Thanks in advance

AC 87 is the checksumm, for 42512 replace to 28 8B
for history i don't know

Thanks. I know that AC87 is the checksum, but I don?t know how to calculate new chks.

Respect to other locations of km I looked for it and found one more location with some info about km, but I don?t find any more.

Could you che my file now?

I watch another file, I think this version has only 3 locations, your file must be ok!

But in the last file, I change data in adress 1445 too, and I don?t know if I have to calc more chks. Maybe drpeter can help me with this file.
