Problem: Creation of the database is suddenly very slow.

Reason: Obviously the WinOLS files are now checked individually by the virus scanner.

Solution: Place the WinOLS data path AND the path for the configuration files in the exclusion list of the virus scanner.


With the latest update, WinOLS and OLS807 can calculate the MED17/EDC17 checksum in the EEPROM. For this purpose, a check box in the checksum dialog has been added that lets you turn this feature on and off can.

This requires a complete project file with correctly assigned processor and EEPROM elements, otherwise the OLS807 is not be recognized.

There seems to be files that require a different method of calculation and, therefore, show all checksum blocks as false. Please send such files as BslToGo, EcuX or OLSx to EVC.
