From file to map in three steps
- 01
Open the file
Drag and drop your .bin between 512 KB and 10 MB. No upload; the file stays in your browser.
- 02
Find the maps
Heuristic scanning detects axis sequences and adjacent data blocks, ranking candidates by confidence.
- 03
Edit and download
Select cells, apply percentage or absolute changes, review the diff, download the modified file.
An editor built for the workshop
Your file stays on your device
All analysis runs in a Web Worker, inside your own browser. Not a single byte reaches a server.
Automatic map detection
Monotonic axis scanning surfaces candidate maps across 8 and 16 bit, LE and BE interpretations.
2D table editor
Heat-mapped cells, percentage and absolute edits, undo.
The original is untouchable
Every edit happens on a copy; byte-level differences stay visible at all times.
Manual mode
When detection falls short, define offset, dimensions and endianness by hand.
A full-featured editor, in your browser
Categorised map list, heat-mapped table, axis labels, diff tracking and one-click solutions — all in your browser, no install.

Works alongside your master tool
The editor works on raw binary (.bin) reads. Files read with tools like Autotuner, KESS3 or bFlash open directly. Checksum correction is left to your flashing tool; a warning is shown on every export.
Beta: always verify the result with your tool before writing to a vehicle.
