Send a file

If you already have the original file from your ECU (read by your garage or by yourself with your own tool), upload it here together with the vehicle and what you need. We review it and reply with the price and the turnaround time before touching anything.

In short

To send your ECU file to Reprogramaciones MBV, use the form on this page: upload the original file (unmodified), tell us the vehicle and what you need (Stage, Eco, a specific function or back to stock software) and send it. Everything reaches us together and we reply with the price and the turnaround time before starting anything. The file has to be the original factory one, unmodified: if it has already been altered by another tuner, tell us and we will see whether it can be recovered. If you are a garage and want the full trade service, take a look at the file service instead.

Upload your file

We will reply here as soon as we have reviewed the file.

Up to 20 MB. We always keep your original file before modifying it.

Would you rather talk it through first? Message us on WhatsApp at 641 125 798 or call the workshop on 918 81 02 66. If you do not have the original file yet, ask for a quote for the read on the quote page.

Common questions

Frequently asked questions

Which file do I need to upload?

The original from your ECU, complete and unmodified, exactly as it comes out of the read. If the file has already been altered by another tuner and there is no original, tell us in the form: we assess whether the factory software can be recovered before doing anything.

Who can use this form?

Both private customers who already have the file read (for example, by their usual garage) and garages sending us a customer's original. If you are a garage and want the full service, with the invoice in your name and trade terms, use the file service instead.

How long does it take to get a reply?

We review your request and reply within 24 hours at most, through the contact details you leave us, with a fixed price and the delivery time for the modified file.

What if I do not have the file yet?

Then what you need is to have the ECU read first. Ask for a quote on the quote page or message us on WhatsApp at 641 125 798 and we will tell you how to go about it.

Is it safe to upload the file here?

The file arrives as an attachment straight to our workshop email. It is not published or shared with anyone, and we always keep your original file before modifying it.
