← All map and hex editors
MapBin is a browser-based ECU calibration service. It advertises file recognition, map editing in real units and a raw hexadecimal editor, together with saved versions and additional tuning tools. The main editor requires an account; some separate quick tools can be opened without signing in.

Editing a file
MapBin says it recognises supported ECU files and presents available maps with axes, descriptions and engineering units. It also advertises a raw hex view with search and editing, user-defined maps, version history and a local browser autosave. Automatic recognition is limited to supported files; inspect the identified ECU, software, map layout and scaling before making changes.
The service lists optional tools such as diagnostic-code management, calculators, datalog overlays and a virtual-dyno feature. Their presence in the product does not mean that each tool is available for every ECU or that a calculated result substitutes for vehicle measurement.
Accounts, files and charges
The public page describes many features as free, with some advanced operations paid per use or through credits. Separate quick tools can have their own charges. Check the current account, coverage and pricing terms before starting a job; the prices shown in the screenshot are historical.
MapBin’s privacy policy says file processing occurs on its servers and describes both account storage for saved files and a browser-side autosave. Review the policy before uploading customer files, and do not assume that browser-based editing means the binary remains only on your own computer.
Checksums and programming
The current public interface says checksums are corrected when saving on supported ECUs. That is a coverage-dependent claim, not a guarantee for every binary or every integrity layer. Confirm the result and the programming tool’s requirements for the particular ECU; vehicle reading and writing require an appropriate interface.
