ECU tuning software includes map and hex editors used to inspect and change the binary calibration files read from an engine or transmission control unit. This directory groups examples by how they are accessed. The listed products differ in supported files, definitions, features and licensing; inclusion is not a claim that every function works on every ECU.
Map editing and hex editing
A hex view presents the underlying file data as bytes. A map editor interprets selected data as parameters, tables or graphs using addresses, data types, scaling and other definitions. Many tuning editors combine both approaches, but a map view is not itself a raw hex editor. Definitions must match the exact file and software version; an automatically detected map or label still needs to be checked. See TunerPro's explanation of binary files and definitions.
Editing a file and communicating with a vehicle are separate steps. A compatible programming tool is generally needed to read and write the ECU. Check checksum handling for the particular file and programming tool; do not assume that an editor or flasher will always correct it. Keep an original backup and verify changes. Alientech's ECM Titanium guide and LTEditor's guide describe their respective workflows.
Desktop and installed software
- WinOLS — EVC electronic. Windows ECU file editor with map search, map displays and raw data views. Optional plug-ins include checksum and definition import functions. EVC: WinOLS.
- ECM Titanium — Alientech. PC software launched from a USB key, using Driver definitions to display calibration maps. It offers table, 2D, 3D and HEX editing; online services and offline use depend on the workflow and available files. Alientech: ECM Titanium.
- MAP3D CLOUD — Flashtec. Desktop map editor with table, 2D, 3D and hexadecimal views, map search and cloud functions. Check current system requirements and licensing with the supplier. Flashtec: MAP3D CLOUD.
- TunerPro — TunerPro. A calibration editor using XDF definitions to interpret and edit binary data, with tables, graphs and a hex editor. Definition availability varies by application. TunerPro overview.
- BitEdit — BitSoftware. An ECU calibration editor with ECU-specific modules and hexadecimal editing. Its vendor distinguishes the editor from ECU reading, writing and checksum correction. BitEdit documentation; BitSoftware: BitEdit.
- Swiftec — Swiftec Lda. Installed software combining map, 2D and HEX views with online databases and automated modules. Although installed locally, its licence states that an internet connection is required to use it; do not assume it works offline. Swiftec features; licence.
Browser-based software
- StageX — Magicmotorsport. Cloud-based editor accessed through a web browser, with map packs and HEX, 2D and 3D editing. Features and charges vary by plan. StageX; plans.
- LTEditor — Llandow Tuning. Free browser-based map and hex editor with project versions, custom or imported definitions and automatic map detection for supported files. Downloads are marked “Checksum not calculated”; a separate corrector covers supported applications. Vehicle read/write hardware is separate. LTEditor overview and coverage.
- MapBin — MapBin. Browser-based ECU binary editor advertising map editing, ECU recognition and a raw hex editor. Check file coverage and service terms with the provider. MapBin.
Choosing an editor
Check the exact ECU and software version, file format and map-definition availability before choosing. Compare whether the required functions need an internet connection, account, licence, credits, dongle or additional modules. Check how original files and project data are stored, especially for cloud services. Confirm checksum and read/write responsibilities separately for the intended workflow.
