V2 just launched

Professional ECU tuning,without the desktop software.

Open a calibration in your browser and edit real maps, with heat, deltas, feathering and version control that behaves like git. New in v2: bring your own definition, correct one that does not quite fit, or build one from a bare binary.

New to this? Your first project is guided from finding a definition to making a change you can undo.

“What does this table actually do, and which way is more?”

What you can do

Everything the editor does

Items marked New shipped in v2. Items marked Premium need the AI agent.

The editor

  • XDF and BIN parsed in seconds: tables, flags, scalars and patches.
  • Edit on a real grid with heat and deltas, several maps open at once.
  • Feather and smooth a region so a change blends instead of stepping.
  • 3D surface plots, and CSV in and out.
  • No install, no VM, no dongle. Open a project on any machine.

Definitions

New
  • Correct any map: address, shape, data type, endianness, scaling and axes.
  • Solve the scaling from two known readings instead of guessing a factor.
  • Map a binary that has no definition at all, table by table.
  • Search the shared catalogue by make, model or ECU and start from that.
  • Export a real .xdf you own, corrections and discoveries included.

The AI agent

  • Ask what any table does and get an answer read off your own numbers. Premium
  • Describe a change in plain language, then accept or reject it as a review. Premium
  • Datalogs read back as knock, lean spots and boost that missed target. Premium
  • Out-of-range warnings on the exact cell, from the limits your XDF declares.
  • Import datalogs and CSV on any plan.

History and delivery

  • Commit snapshots and diff any commit against your working state.
  • Revert with a typed confirmation. Nothing is overwritten silently.
  • Subprojects: several ECUs in one project, each with its own history.
  • Export a flashable BIN when you ask for one, not before.
  • Talk to the car owner in-app: request logs, send updates, share files.

New to tuning

Never tuned before?

A five step walkthrough runs on your first project. It helps you find a definition for your car, opens a real map, and shows you how to make a change you can undo. The terms are explained where you meet them, so you are not looking anything up.

Start your first tune

The editor, the catalogue and the guided start are on both plans. Cancel any time.

Try it

This is the real editor

Not a screenshot. The same window and grid components the product ships, running on a demo table. Drag it around, select a region, nudge the values.

Roadmap

What's coming next

Customer mobile app

In progress

A phone app for your customers: chat with their tuner, get tune updates, and manage their vehicles from their pocket.

Team & shop management

Next

Multiple tuners under one shop, shared projects, per-seat billing and role-based access.

More file formats

Planned

Beyond XDF and BIN: additional definition and calibration formats so more platforms are covered.

Open your first map

Upload a definition and a calibration and you are editing in a few minutes. EcuXprt is in early access and ships weekly.
