I have a A3 8P dash with reference 8P0920982C, diesel with miles/hour in the odometer.

I have read flash and eeprom with no problems with SMOK UHDS.

I tried to convert this dash into a 8P0920932C, the same dash but KM/h.

I was able to get it modifying the EEPROM (after comparing 20 different dashes), but the odometer says "DEF".

I have the Flash and the EEPROM of an original 8P0920932C, so I was thinking what happens if I copy Flash and EEPROM in the 8P0920982C dash ...

I tried to reflash 8P0920982C with VCP, but VCP says file format is not ok.

Is there a way to convert the flash of 8P0920932C (.bin file) in a sgo?? frf??? .... so I will be able to flash the 8P0920982C unit with VCP or Odis??

If not, is it possible to write 932C flash on 982C flash?? What tool can I use (SMOK does not write flash, only read).

Post dumps or copy immo data is the easy way.

I am also interested of transform these dasehs from miles to km. I think i know location in eeprom of speedo scale, but i think there is checksum that also need to be calculated. If you reflash your dash if will work, but SMOK can only read micronas. Latest version of vdoeditor maybee can modify eeprom.

These are the files of 932C

Yes, I am sure the problem is in Checksum, the problem is I do not know where the Checksum are ....


If I am not wrong, I changed 16 positions in EEPROM.

This is already discussed and solved in this thread. Compare files and see differences.

Hi

THX in advance  ...

The speedometer scale is 260 km/h or 280 km/h???

Regards.

After study more than 20 eeproms form A3 8P, this is what I found

POS     MILES     KMH
2C2      F7          E9

2C3      07          04
2C4      C8          97
2C5      2F          27
2C6      43          80
2C7      3F          31
2C8      15          80
2C9      62          61
2D2      0B         00
2D3      08         05
2D4      47          00
2D5      30          28
2D6      60          00
2D7      40          32
2D8      95          00
2E5      06          08

The problem i have is about cheksum ...

yes, that is offsets for speedometer map.
About CRC i know one guy which can help for sure. he is on DK forum - not here.
For sure he can find the algorythm and calculate new checksum.
I think easyest way is just to reflash your dash if you have xprg.

kantusjack // 280 kmh

Hi,

I used SMOK ... this tool can read, but can not write FLASH ...

Mine is a little bit different ...
