hi

I have problem to correct checksum edc16c31.
winols says that file ori is badly corrected.


kees and mpps say that checksum of the modified file is not correct.


Can you correct? with what program do they do it?


the mod is to try to raise the engine speed idle from 700 to 800 revolutions

Your mod file CS is ok.

If ORI file have bad checksumm than something is done with that file already.
Did You can write EDC16 VOLVO by Kess or MPPS? I have done them only with KTAG.

I did read and write with ecu out of the car by k-line.


ori read with mpps.
mpps writes, and at the end it gives an error.
Kees no longer lets write. it says checksum error.


ori file if you let write

I can say one!
with volvo ecu all time is problem with ck and only what show car after write mod file show ECM-7700
Volvo need CK from factory algoritm!!
It is same ECM titanium if you use original dump you can automatic search driver for maps if you use ecu without ck from factory ecm not work with automatic driver searching.
Best regards.
