hi,
in dashboard dump you can see from 0x00-0x7F...hex km value and hex not value,for example
002F1401hex --> 3085313,so if you want 130255 ->130255x10 ->1302550 ->hex 0013e016,further
you can see FFD0EBFE and its the 002F1401xorFFFFFFFF ->FFD0EBFE,so if you edit first
hex value to 0013E016 you must edit even second value like follows
0013E016xorFFFFFFFF -> FFEC1FE9,so now you edit all hex values from 00 to 7F with
0013E016 and FFEC1FE9 ----it is 130255km.

in dashboard change all hex values with the same hex number 0013E016 and FFEC1FE9
from 00 to 7F .
In the bsi as You can see you have from adress 326 to 362
hex value 0904C8FB2E and last 1C04B5FB2E all this hex values you must change.
You wrote that you have got Tachosoft 21 so look in and try .
Tachosoft 21 Citroen C5 bsi 95128 130255 - value in window is D61F16E013 so
now you can edit all hex from 326 to 362 ,0904C8FB2E - D61F16E013........to last
hex 1C04B5FB2E - D61F16E013.
So now you have changed km mileage in dashboard and BSI ,this is value which
appears on dashboard display ,but another km mileage is stored in BSI and engine ECU.
This km You can read with LEXIA or PPS only,but it is better to delete it if you want
real km keep in secret.
In BSI bulletin /fails history/ begin sometimes from line 800 and sometimes from line 1000,
it depends
and you must put in FFFFF to the end of memory.In engine ecu you have to check first time
with diagnose Lexia or Planet, sometimes it is empty.but if the mileage was 308000km,
i don't believe it.
