Book Online

If your vehicle can't be remapped through the OBD port, our postal ECU remapping service offers a fast, professional solution. At Advanced Remaps, we provide custom postal ECU tuning and bench ECU remapping for customers across the UK, with a typical 48-hour turnaround from the moment your ECU arrives with us.

Whether your ECU is locked, requires a bench unlock, or simply needs a custom calibration, our experienced technicians use professional programming equipment to safely read, modify and write your ECU. Every remap is tailored specifically to your vehicle and your requirements, delivering smoother performance, improved drivability and, where appropriate, better fuel economy.

Our postal remapping service means you don't need to travel to our workshop. Simply remove your ECU, send it to us using a tracked courier, and we'll complete the work before returning it ready to reinstall.

What Is Postal ECU Remapping?

Postal ECU remapping allows you to have your vehicle professionally tuned without bringing the entire vehicle to us.

Instead of visiting our workshop, you simply remove the Engine Control Unit (ECU) and send it to us by post. Once received, we professionally read the original software, create a custom calibration, programme the ECU using specialist bench equipment, carry out quality checks, and return it ready for installation.

This service is ideal for vehicles that:

• Cannot be remapped via the OBD port

• Require a bench unlock before tuning

• Have locked Bosch MG1 or MD1 ECUs

• Require specialist bench programming

• Are located anywhere within the UK

Because the ECU is programmed directly on the bench, we can safely work with many of the latest security-protected engine control units that cannot be accessed using conventional diagnostic equipment.

Why Choose Advanced Remaps?

Choosing the right tuning company is just as important as choosing the remap itself.

At Advanced Remaps, every calibration is tailored specifically to your vehicle. We don't simply install generic files. Instead, your ECU software is carefully modified to suit your engine, hardware and requirements while remaining within safe operating limits.

• Professional bench programming equipment

• Custom-written remaps

• Performance, economy or balanced tuning options

• Safe ECU unlocking

• Typical 48-hour turnaround

• Excellent customer reviews

Whether you drive a daily commuter, performance vehicle or commercial van, we can advise on the most suitable tuning solution.

Bench ECU Remapping Explained

Many newer vehicles feature advanced ECU security that prevents tuning through the OBD port.

This is where bench ECU remapping becomes essential.

Bench tuning allows us to connect directly to the ECU using professional equipment. This provides full access for programming while maintaining the integrity of the original software.

We regularly work with:

• Bosch MG1 ECUs

• Bosch MD1 ECUs

• Delphi ECUs

• Continental ECUs

• Marelli ECUs

• Siemens ECUs

• Denso ECUs

If you're unsure which ECU your vehicle uses, simply contact us with your registration and we'll check for you.

Safe and Professional ECU Programming

Every ECU is programmed using professional tools and verified before dispatch.

Unlike generic tuning files, our custom calibrations are designed specifically for your vehicle, helping deliver reliable performance while maintaining safe operating parameters.
