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.
