Thank you many times Steveleo. Can you also edit operating hours in ECU Continental 5WP46593 EMS SDI 9? Now it is 2974 hours and I need 980hours. AT25128 EEPROM inside. Many thanks.

There is also km in the ECU, not only hours. I made it once manually, but didn't make a tool for it and manully sucks. When i have some spare time i can check again. Pretty sure someone here on forum has it in his tool or a script for it.

Check adress 12A-135 for hours :-)

Yes, I tried. I changed like this "70 FF 3A 43 01 00 9D DA 00 00 39 39" on the address 12A-135, but on diag still show 2974 hours :/

Ok then this must be another version, hours are calculated normally dec*36000=hex so look in in the dump for a simular value

I was searching, but no result :/ I have found one interesting string, that is from adress E8 to F3. It is "14 16 62 06 15 16 62 06 16 16 62 06" but cannot calculate it to find out what is it. What do you think?

**steveleo** · 18th September, 2020, 02:40 PM

E8 to F3 -> 0x06621614 = 107091476 dez / 36000 dez = 2974,763222... -> wanted hours * 36000 convert to hex (press F5 in windows calc) and enter it in reversed order. reversed means lowest byte first, but you see with the sample value i took from your dataset.

980 hours would be 0x021A5480. or in correct dataset order 80541A02 (repeat three times)

Many THANKS Steveleo. You are STAR :-) But, when I wrote this 3 strings "80 54 1A 02 80 54 1A 02 80 54 1A 02" on diag show 0 operating hours. I think there will be some checksum, or something.

i don't know about a checksum. and didn't see one. maybe try slightly other value? Or you do the good old "let the car run for one hour" and read again.
