TOOLING
WinOLS — (EVC Electronic GmbH)
Definition
The industry-standard professional calibration map editor. Windows desktop, perpetual licence at €3,000-7,000 plus mandatory maintenance + separately-purchased Damos packages.
Why workshops care
Universally recognised by tuners as "the Photoshop of map editing". Steep learning curve and premium price; large up-front investment puts it out of reach for many independents.
