WinOLS is a program specially designed to rewrite the memory of an ECU. It makes searching and finding maps easier. These can then be named, viewed and modified in various ways. Various functionalities are available to adjust the data.

All data and maps are stored in project files. These project files contain all information that has become known during the editing of a particular controller. Other data, such as customer name, license plate number and photo files can be added.

2D graphic or hex/decimal dump

The display of the raw data is available in 2D graphic or hex/decimal dump. The automatic processor detection distinguishes between program and data areas.

Functions effectively

Field search functionality as well as automatic data entry facilitate efficient work.

2D/3D chart or table

Maps are easily displayed in 2D/3D graphs or tables.

Auto search

A function for automatic search in ECU and software numbers.

Integrated checksum correction

The idea of the integrated checksum correction has been continued. By using DLL files, the algorithms have been removed from the main program. This makes them independent of the version used.

Import and export of binary files

Import and export of binary files, Intel and Motorola hex files. All types are compressed, coded and can be wire-swapped. They can be sent directly by mail.
