Winols Checksum Dll
Annalisa Vanzanten
2. Open Winols, and after you will see the empty working box, picture 1A. Now drag and drop your ecu file onto this box as in picture 1B. Now in picture 1, you can see there are 3 checksums that need correcting, Winols will do this for you.
WinOLS operates a points system in order to purchase checksums and plugins. Points can be purchased individually or in packages at discounted rates. Any excess points can be kept in credit on your account to make purchases in the future.
Hello. Kess V2 is just a tool to read and write the file to the ECU. In order to make calibrations, you need ECM titanium or Winols. Kess V2 often corrects checksum but not always. ECM also corrects checksum. Checksum is used to verify data integrity. With wrong checksum, car will not even start.
Kess, ktag and ecm is subscription based on yearly fees. Each one has a individual subscription fee which can be quite costly. WinOls is the better tool but requires more experience. I have been using ECM titanium and alientech for 1 year now. It's a good tool but I've recently bought AUTO TUNER which is mainly for the newer cars but is wayy faster.
