EVC WINOLS SOFTWARE
What WinOLS Does
Purpose-built for ECU memory editing — nothing more, nothing less.
WinOLS is written specifically to modify the memory contents of ECUs. Every feature — map search, version control, checksum correction, DAMOS import — is built around that single purpose. It’s why professional calibrators use it as their primary tool.
Map Search, Naming & Visualization
WinOLS finds maps in raw ECU data and lets you name, label, and view them in 2D or 3D. Once named, maps are reusable across projects — no hunting from scratch on every file.
Project-Based Workflow
Every ECU job lives in a project file that stores all map data, customer info, vehicle details, and attached images. Up to 200 commented versions of one original file — every change tracked.
Checksum Correction
Checksum plugins calculate and correct checksums even while the engine is running. Covers Bosch MDG1, MED17/EDC17, Siemens Tricore, and many more.
DAMOS / ASAP2 Import
Import manufacturer DAMOS and ASAP2 definition files to bring labeled map names, scaling, and sampling points directly into your WinOLS project.
LUA Scripting & Automation
Automate repetitive calibration tasks with built-in LUA scripting. Write scripts to batch-process files, apply standard edits, or build custom workflows for your shop.
Deep Plugin Ecosystem
Extend WinOLS with importers for xdf, xcal, NewGenius, CmdFlash (Alientech), and tester files. Machine-translate German map names to English automatically.
