Pick your
ECU.

Upload your file, let it be checked, pay. You get the patched bin and the matching XDF as an instant download — ready for your own ECU.

Before you upload

Stock files only.
Freshly read.

This is where almost every failed upload goes wrong. Please read these three points before uploading — they are not policy, they are a technical requirement.

01

Stock — no tune, no add-on patches

The file must be exactly what the ECU left the factory with: no tune, no stage, no catalyst or DPF removal, no patched-in launch control, no ignition cut, no pops code. The only exception: EWS-off may stay in.

02

A fresh full read from your car

Read directly from the ECU, complete and including the bootloader section. An old backup from some time ago is not enough — the file has to match the current state of your ECU.

03

No files from the internet

Bins from MS4X, forums, collections or file swaps are not supported. They come from a different car, are often already modified, and will not run on your ECU.

If any of this does not match, the check rejects the file and tells you why. Nothing is charged and nothing is stored.

How it works

Four steps,
one download

Your file is checked before you pay. If it does not fit, you pay nothing at all — nothing is charged and nothing is stored.

01

Choose your ECU

The product page lists what can be switched per slot and what you need for it.

02

Check the file

Upload your full read. The shop identifies the ECU and its software and checks that the file is complete and stock.

03

Pay

Secure payment via Stripe. Patching happens only afterwards — nothing is done to your file before that.

04

Download

Patched bin plus customer XDF as a ZIP, link valid for 7 days. Later updates for your car are free.

The shop does not correct the checksum. You do that with the MS4x tool you also flash with. Flashing is at your own risk: a verified full read and a tested recovery path are part of the job.

Questions

Before you buy

Why do I have to upload the file before paying?

Because only the file shows whether the product fits your ECU. The shop checks the software and its stock condition before any money moves. That way you never buy something that will not run on your car — and if it does not fit, the check tells you exactly why.

My car is already tuned. Does it still work?

No. The patch hooks into fixed locations of the stock software; an already modified file has moved or overwritten them. Flash your ECU back to stock, take a fresh read and upload that. You do your tuning afterwards, in the free slots.

I have launch control, ignition cut or EWS-off. Is that okay?

EWS-off yes, that may stay in. Patched-in launch control, ignition cut or pops code, on the other hand, not at the moment: the combination with the map switch has not been approved yet. The check detects such additional code and rejects the file before anything is charged.

Can I use a bin from the internet?

No. Files from MS4X, forums or collections come from a different vehicle and will not run on your ECU. It has to be a fresh full read from your own car.

How do I pay?

Through Stripe, the payment provider. Your card details are only ever entered there and never reach this server. Which payment methods appear — card, PayPal, Klarna — depends on what is enabled in the Stripe account.

When do I get the files?

Immediately after payment. Patching takes seconds, then the ZIP is ready to download. If you provided an email address, you also get the link by mail.

Do I have a right of withdrawal?

In principle yes — but for digital content it expires as soon as delivery begins at your express request. That is exactly what you confirm with a checkbox during checkout, because otherwise the download could not start right away.

What happens to the file I upload?

It is checked, patched and then deleted automatically. The only thing kept permanently is your customer key and, if supplied, your email address — that is how we recognise you for free updates. Details are in the privacy notice.

What does a later update cost?

Nothing. Upload your bin again and enter the same email address you used for the purchase: the shop recognises you and sends the download link to that address without payment. That holds even if your old link expired long ago.

Not sure it fits?

Ask first.

Send us the car, the ECU and what you have in mind. A short message beats a file that does not fit.
