Read Flash Memory Of Motronic 4.3 - Data Integrity?

[German850R]

Hi,

yesterday I used Motronic 4 Suite to read the flash memory of a Motronic 4.3 which is in a friend's tuned T5. We wanted to look at some maps and unterstand what's going on.

Download took about 45 minutes and went with no issues.

However, if I open the bin in Motronic Suite, it does not recognize the maps properly. The maps look rather like scalars than maps and are just not useful.

Looks like the maps are sort of at an offset to the stock file in terms of their location.

You can download the bin here: https://www.dropbox.com/s/e7wuxtohv7jj1mo/0261203627_1267358234_downloaded_M43.bin

Any suggestions?

Thanks

Chris

It doesn't look right, particularly at the end.

If you take the block with mostly 00 at the end and put in somewhere around 0x6000, then most of the stuff at the end will align better with stock.

There has probably been some read errors at some point, and Motronicsuite doesn't handle it very well.

Maybe the read address keeps increasing, while the file pointer for writing the read values doesn't increase when nothing is received.

You should try to read it again. Maybe try with my program.

'?do=embed' frameborder='0' data-embedContent>>

You can also read some small spots here and there to check.

For example 8 bytes from FF00:

Write 03 08 FF 00 and push Test button

Steeling some bits from the stock file 600D-6100 and D24E-D300 seems to fix the file.

Thanks a lot for your advice. Will give it a shot .
