This method how to change km for Peugeot 207 2010 Bsi Control johnson with eeprom 95128

1st variant
for exemple we need 50.000km
set the calculator Dec
50000 *10 = 500000 ;
500000 To Dec = 07 A1 20 hex ;
07 A1 20 hex = > Not F8 5E DF ;
So the km is F8 5E DF

this 2nd variant to calc same value
km + add 0 = 500000 > 07A120 hex > Not F8 5E DF
Done same value above

write the value 8 times, start from line h0x4c03

Figured I would add this one, haven't posted here in a while.

Lincoln MKX 93c76

Files are calculated in Km so if you need Miles convert to Km first.

100,000.000 Km

0050: xx xx xx xx 0a 19 00 e1 f5 05 0a 19 00 e1 f5 05
0060: 0a 19 00 e1 f5 05 0a 19 00 e1 f5 05 0a 19 00 e1
0070: f5 05 0a 19 00 e1 f5 05 0a 19 00 e1 f5 05 0a 19
0080: 00 e1 f5 05 0a 19 00 e1 f5 05 0a 19 00 e1 f5 05
0090: 0a 19 00 e1 f5 05 0a 19 00 e1 f5 05 xx xx xx xx

First two bytes CS, last four mileage inverted to decimal = Km X 1000

00 e1 f5 05 inverted 05 f5 e1 00 to decimal = 100,000.000

CS set calculator to WORD f505+00e1 = f5e6 NOT 0a19

Alrighty, if you do this next one manually, you are a sucker for punishment as there can be a couple of hundred lines to edit.

This is a better one to do with scripts because of the time involved but thought I would post it so people could understand how it works.

Fujitsu processor found in a lot of newer cars, haven't verified on a whole lot of them but some Toyota and Hyundai use the same algo. I also didn't check to see if the mileage is in the same lines in each processor.

When looking at an original file you will see the mileage is a different value in most lines, as the processor counts up, but when editing it the mileage values can all be the same.

Refer to the pic below of 10000 Km.

First off, 0x22-0x23 is 06a6, which is our constant of 06a4 + 02 (0x26-0x27)

Now to the calculation, and this will be referring to line 0x30 only. The mileage is in straight decimal as at 0x34-0x37, which is the easy part.

The bytes at 0x30-0x31 are not edited and the CS (0x32-0x33) is calculated as follows....

The CS is our constant of 06a4 plus each other byte in the line (0x30-0x31 and 0x34-0x37)

0x30: 00 02 CS CS 00 01 00 00: CS = 06a4 + 00 + 02 + 00 + 01 + 00 + 00 = 06a7

That gives us a corrected line of: 0x30: 00 02 06 a7 00 01 00 00, now just up to a couple of hundred more.

Have fun with this one.

I follow this thread because I want to learn and do things yourself.
Right now I'm trying to change the VIN in a dump (93C56 VDO) from an BMW E39 -97.
I think I've found the right place, now starting to work, for I find no program that can confirm what I do.
So now it would be fun if the pros come in and teach us beginners

Per your screenshot it seems that VIN number is RB86354. But it doesn't seem to be a legit VIN number.

Thank you, You confirmed that I succeeded.

In this case, are used only the final seven characters of the VIN, number on BMW.
So now I try to modify km to 5000. But I do not understand how to use XOR in the examples above.

Verision:
VDO 110.008.784/022
SW:5.0
HW:0.5

Current: 187363 km
change to: 005000 km

After many attempts, I think I got it right but are not sure.

40: 8E 2D 10 18 43 E1 8E 2D 10 18 43 E1 FF FF FF FF

On other cars where I changed from, say, 234556 km to 185000 km the result is 185022 km when it is finished, why is it so?

This could be a good educational topic.

my solution of DCM3.4
---------------------------------------------------------------------------------
Vin:VF1KW05B545040074
K m : 325791 km
Err 1: 325779 km
Err 2: 325700 km
Err 3: 0 km
---------------------------------------------------------------------------------
1. search all hex values contains 04F89F
2. change mileage Hex TO dec 04F89F -> 325791 km


3. change mileage dec TO hex 246791-> 03C407



4.Replace values 04F89F to 03C407 in all founded places
5. change km to 246791 km in all founded places
04F89F= 325791 km
04F893 = 325779 km
04F844 = 325700 km

and Replace Values 04F893 to 03C407
Values 04F844 to 03C407

Coriction crc New Milage 246791 km ok !!!!

This Method how To change Peugeot 308 2012 with Continental Dash 93C66.
for exaample 50.000

Now come on to calc the km in the Dash manually

50.000 *10 = 500000 to hex 07A120 > swap = 20A107 xor FFFFFF = DF5EF8

now replace the 1st/2nd value in column 1 20A107 and column 2 DF5EF8

0x00: 0C A2 20 A1 07 00 DF 5E F8 FF 20 A1 07 00 DF 5E F8
0x10: FF 20 A1 07 00 DF 5E F8 FF 20 A1 07 00 DF 5E
0x20: F8 FF 00 00 00 00 00 00 00 00 00 01 09 01 F8 00

[hcip]

I hope this can be easy to understand
1) set to window calculator to hex
2) enter kilometer value
3) xor to FFFFFF

Tata zeta with eeprom 93c56

dec 100.000km /16 = 6250 to hex 186A xor FF FF = E795 invert byte = 95E7

Good luck
