Ecuno_
Browser-based BIN editor · Bosch ME7/ME7.5

Edit ECU maps
in your browser.

Upload a BIN, define maps, edit values, compare against stock, and export the modified file. Ecuno focuses on Bosch ME7/ME7.5 workflows.

Built for DIY tuners and ME7 hobbyists — nothing to install, your original stock file stays untouched, and it works from any browser.

// 01 — CAPABILITIES

Built around manual ECU editing.

Ecuno does not tune the file for you. It's the manual workbench — you decide every change, and the tool keeps the stock reference, the diff, and the checksum honest.

MAPS

Manual map editing

Create named maps from addresses, rows, columns, data type, factor, offset, and axis locations. Edit values in a table view instead of working only from raw hex.

DIFF

Stock vs modified

Keep the original file as reference. Changed cells stay marked, and selected values show stock, modified, and delta.

CSM

Checksum validation

Validate and correct checksums for supported ME7 / ME7.5 files, and see checksum state before export instead of shipping blind.

VCS

Project history

Keep maps, notes, and edited versions together instead of saving random files like final_final_v3.bin.

XDF

Map definitions

Work from manual definitions and importable map packs. Bring your own — no proprietary packs are bundled.

// 02 — WORKFLOW

From stock BIN to modified BIN.

Start from the original file, define the maps you need, edit values, review changes, and export a new version.

01

Open the stock file

Upload or open the original .bin file. Ecuno focuses on Bosch ME7 / ME7.5 workflows.

$ open      stock_file.bin
$ family    Bosch ME7 / ME7.5
$ status    stock loaded
02

Define and edit maps

Create maps from known addresses, axes, data type, factor, offset, and units. Edit values in table view and keep the original file as reference.

$ map       KFMIRL @ 0x1C830
$ size      16 x 16
$ unit      % load
03

Review and export

Check what changed against stock, validate and correct the checksum, then export the modified BIN.

$ diff      4 maps changed
$ checksum  validated + fixed
$ export    tune_v03.bin
// 03 — COMPATIBILITY

Starting with Bosch ME7 / ME7.5.

Ecuno focuses on one ECU family first. The goal is to make ME7 / ME7.5 map editing, stock comparison, project saving, checksum handling, and BIN export reliable before adding more ECU families.

Initial focus
Bosch ME7 / ME7.5
Early use case
VAG 1.8T / ME7-style BIN editing
Map definitions
User-provided definitions
No built-in proprietary map packs.
Checksums
ME7 / ME7.5 validation + correction
Live for supported ME7 files. Coverage will expand with more families.
Not claimed
Universal ECU support
More families are on the roadmap, not a current claim.
NOTE

Supported variants are listed clearly. If an ECU family is not documented, assume it is not supported yet.

// 04 — ROADMAP

Live today, with a clear roadmap.

Ecuno is a working editor now — not a promise. Everything that's live is above; everything still planned is gathered here, in one place, so nothing else on the page has to hedge.

Status
LIVE

Available now

The browser editor, 3D map view, stock comparison, second-BIN compare, project saving, version history, map definitions, the datalog viewer, BIN export, and ME7 / ME7.5 checksum validation are all working today.

COMING SOON

More ECU families

Expand carefully beyond Bosch ME7 / ME7.5 once the core editor, comparison, and checksum systems are proven.

COMING SOON

Advanced imports

A2L and DAMOS definition formats on top of the manual definitions, .xdf, and map packs available today.

// 05 — FAQ

Common questions.

No. Ecuno is an editing and workflow tool. It helps you inspect, edit, compare, validate, and organise ECU binary files. It does not create a safe tune automatically.
The first focus is Bosch ME7 / ME7.5 style workflows, especially common VAG 1.8T use cases. The editor, comparison, definitions, and ME7 checksum handling work today; wider ECU support will be added carefully over time.
Ecuno is designed around imported or user-provided definitions. No proprietary or copyrighted definition packs are bundled. You bring your own definitions, or use community-shared ones.
Nothing. Ecuno is free — create an account and start editing right away. Every feature that exists today is available to everyone, no card required.
Yes. Checksum validation and correction are live for supported Bosch ME7 / ME7.5 files — Ecuno shows checksum state before export and can correct it. Coverage for other ECU families will expand over time; universal correction across all ECUs is not promised.
Yes. Ecuno does not replace calibration knowledge or judgment. It is meant to make the editing workflow cleaner and reduce tool friction — not to make decisions for you.
