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.

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

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

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

Well 99DC is first 2 byte

Here is an oldie but a goodie, and I have not seen many successful corrections for these because it is a bit weird to calculate.   This is a tested and successful algorithm.

This is from Holden Commodore VS 24c44, but applies to older GM with 24c44 with only 32 bytes of data in the file.  The first 8 bytes are ignored, the mileage is repeated 3 times for the last 24 bytes.

Calculating mileage to hex string is all done in hex.  First word is checksum last three are mileage.  Each byte is followed by it's xor.  Calculate these first, then use the table below to convert them (don't get confused with xor, the conversion table is different).  Then swap the nybbles, ex:6c 93 becomes c6 39


123,456Km  (file attached)

CS: 12+34+56 = 9c with xor first CS = 639c
CS/Mileage....639c 12ed 34cb 56ac
Converted.....6c93 847b c23d a653
Nybble swap..c639 48b7 2cd3 6a35  

Conversion table:
0=0
1=8
2=4
3=c
4=2
5=a
6=6
7=e
8=1
9=9
a=5
b=d
c=3
d=b
e=7
f=f

Have fun.
