ECU · TCU reverse engineering lab

Control unit firmware, reverse engineered by family.

We work through a controller family once, down to its code and calibration structure. Tuners, file services and tool makers get the results: map definitions, function analysis and automated tools that hold up across software versions.

Services

Three ways to work with us

Research done once is sold many times. That keeps products cheap and lets custom projects start from work that already exists.

Automated · per file

RE products

Upload a read. Our server identifies it and shows what it found, with addresses hidden. Pay, and download the full result.

Project · B2B

Custom reverse engineering

A controller that is not in the catalogue, or a function you need understood. Fixed quote, deposit, NDA, milestones and written deliverables.

Tuning files

Need a tuned file rather than research? Our file service handles everyday tuning, with the lab's knowledge behind it.

Capabilities

Controller families we have reversed

Families with research done in our lab. We publish what is possible on each one, never how it is done.

Custom RE

How a custom project runs

For tuners, file services and tool makers who need a controller or a function understood properly. You know the price and the stages before any work starts.

  1. Inquiry

    Tell us the controller, its hardware and software numbers, and what you need.

    you send read · IDs · goal

  2. Feasibility and quote

    We check the file against our research and reply with scope, price and timeline.

    you get fixed quote

  3. NDA and deposit

    We sign an NDA if you need one. The deposit starts the work.

    you get start date

  4. Milestones

    Work runs in agreed stages. Each stage ends with a short progress report.

    you get stage reports

  5. Delivery

    Map definitions for your editor, a written function report and tools where they help.

    you get definitions · report · tools

Results can be exclusive to you. We agree exclusivity in the quote. Otherwise the research goes into our catalogue, which is what keeps product prices low.

How we work

Your files, our methods, clear limits

Three rules that apply to every product and every project.

Results, not methods

We deliver definitions, reports and tools. Our methods and research tooling stay in-house, and previews hide addresses until purchase.

Your files stay yours

Reads are processed on our own server, used only for your request, and never shared or resold. NDA on request.

Emissions and immobilizer work

We also deliver emission-system solutions (DPF/FAP, EGR, SCR/AdBlue, CAT, OPF OFF) and IMMO OFF. They are for off-road and motorsport vehicles only, never for use on public roads. The customer confirms this with every order and is responsible for how the vehicle is used. IMMO OFF requires proof of ownership.

FAQ

Before you ask

Who do you work with?

Tuners, file services, workshops and tool makers. If you are a driver looking for a tuned file, the REMAPIA file service at files.remapia.com is the right place.

Do you do DPF, EGR, AdBlue or IMMO OFF?

Yes, for off-road and motorsport vehicles only. You confirm this in the request; IMMO OFF needs proof of ownership.

My controller is not on the list. Can you still help?

Often, yes. Send the hardware and software numbers. You get a feasibility check before you pay anything.

What do I receive from a custom project?

Map definitions for your editor, a written report on the functions you asked about, and tools where they save you work. The exact list is part of the quote.

Is a custom result exclusive to me?

It can be. Exclusivity is agreed in the quote and priced accordingly.

Which files do you need?

A full flash read as a .bin from a common tool, plus the hardware and software numbers. We tell you if anything else is needed.
