Tool comparison
WinOLS by EVC Electronic is the de-facto professional map editor for reading and modifying ECU calibration data. It opens raw binary dumps and OLS project files, automatically detects likely map locations, and lets tuners visualise and edit 2D/3D tables for injection, boost, torque limiters, EGR, DPF and drivability. It includes checksum-correction modules for a wide range of ECUs, difference/compare tools, and a large paid database (DAMOS/A2L and labelled OLS projects). Used by professional file-writing services worldwide, it works alongside flashing hardware such as KESS3, K-TAG, CMDFlash and Autotuner that actually read and write the ECU. WinOLS itself edits files and does not communicate with the vehicle.
Swiftec is calibration software combining a map editor with an extensive definition system for locating and labelling tables inside ECU firmware. It is known for solid coverage of Bosch diesel and petrol ECUs and provides automatic checksum correction plus tools to find maps and switches for EGR, DPF, DTC handling, torque and boost. Tuners open a dump, apply a matching definition, and edit calibration values with context, similar in spirit to WinOLS and ECM Titanium. It operates purely on binary files, so it is paired with a separate flashing interface to read from and write to the vehicle's ECU. It suits tuners wanting structured, definition-driven editing.
WinOLS (ECU Editor / Map Editor, EVC Electronic) and Swiftec (ECU Editor / Map Editor, Swiftec) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.

Whichever you flash with, Softechpro Solutions auto-applies DPF/EGR/AdBlue/DTC-off modules and Stage patterns with automatic checksum correction across ~1,400 firmwares on Windows & macOS — the fast way to get the actual file edits done.
