hello

what happening when put original dump back ???
what interface you use ?

regards

[mastaflex]

i think it' due to a bad checksum calculation

[niki85]

i think too but
it must work well with original dump

maybe I am wrong .. but ... I believe your dash have inside 95320 and you have been readed only like 95160 ...
You must open it to check this. If is like that , then you are in trouble.

doesn?t matter , open it and check with your eyes.

Of course you read the mileage correctly, mileage is a very simple calculation on adress 0000. It is all about the checksum, your software edited too much data, you only have to modify 2 checksum instances. The calculation of this cluster is very hard, it seems like your software cannot do it.

Put back original dump if it was well saved...and find a good algoritm for chksum calculation.

As i told you in previous message , open cluster and check what eeprom you have there .
Even if your tool can read the mileage correctly is possible to have there other eeprom.

Why? Dump is 2kb and data goes to 7F7 so chip is 95160.

If 95320 then dump is 4kb and data goes to FFF.

Sorry I thought it was a 24c32 it that cluster ? I will stand corrected !

Thanks Tachonow,DrPeter,I try to put back ori file.
