Dashboard School - Manually Changing Mileage

[joshp]

Hello all,

Im all for learning code algorithm's would any care to explain the BCM odometer code for Holden (CHEVROLET) Colorado 2018? I can normally figure code out from others bin file changes, but this has me scratching my head.

e.g

226,000kms

0xF7 - 00 B4 DC 00
0x166 - 00 B4 DC 00
0x1C4 - 00 B4 DC 00

DCB4>dec=56.500x4=226.000

Looking at working on a 93a66 in a hilux, altered odo now high beam and traction lights work in opposite. Happy to share how to program odo manually if anyone is interested.

Hi Sparkie66,

Could you please share how you work on a 93a66 in a hilux to alter odo please?

Thanks.

Hello all

Would any one care to explain hyundai ir40 93c66 16 bit eeprom code?

060 FF FF FF 8F ED FF FF 8F ED FF FF 8F ED FF FF FF

this would be 127000

Many thanks

Josh

FF8F TO DEC + EDFF TO DEC

65423 + 60927 = 126350

Would that be the correct way?

[clusters]

Not the correct way at all, this is a Denso algorithm, search the forums it has been discussed to death.

Good Work everyone, help on honda ridgeline mileage algorithm.

Thanks to all

DCB4>dec=56.500x4=226.000

More easy friend.... Dec * 64 to Hex inverted

How about Skoda Fabia II 93c86

Please help

[QUOTE = joshp; 4166468] Olá, todos. Alguém

se importaria em explicar o código eeprom de 16 bits do hyundai ir40 93c66?

060 FF FF FF 8F ED FF FF 8F ED FF FF 8F ED FF FF FF

seria 127000

Muito obrigado

You should try a little harder.ED 8F FF >xor FF FF FF >=127000.

Litlle about Bosch ME7.3.1 and ME7.3H4 Fiat and Alfa Romeo eeprom km milage
Did some experimenting on the ME7.3.1 and found the following that is stored in the eeprom:

Odometer [km] 02h-04h.
3 bytes LSB first.
Odometer [km] = value / 10

Max engine RPM reached [rpm] 06h
1 byte
RPM [rpm] = value * 40

Number of overrevs 0Ah
1 byte
number [1] = value

Time in overrev [ms] 08h-09h
2 bytes LSB first
time [ms] = value * 100

2 byte checksum for 00h-0Dh is located at 0Eh-0Fh (LSB first) and is calculated as 10000h - (sum of 00h-0Dh).

Example:
01 01 40 E2 01 00 1E 00 0A 00 64 00 00 00 4F FE

Reported by Alfa OBD:
Odometer, km: 12345,6
Number of overrevs: 100
Max engine speed counter, msec: 1000

Max RPM reached: 1200



01h+01h+40h+E2h+01h+00h+1Eh+00h+0Ah+00h+64h+00h+00 h+00h=01B1h
10000h-01B1h=FE4Fh
Checksum= 4Fh and FEh (last two bytes)
