Frequently asked questions

An online service reserved for professionals: you upload the original read of an ECU, choose the services (Stage 1, options…) and download a modified file with corrected checksum, ready to write with your tool.

With the reading and writing tools on the market: Autotuner, KESS3, K-TAG, Flex, bFlash, CMD Flash, PCM Flash, Dimsport… Upload the file exactly as your tool read it, unencrypted.

Instantly when a validated map exists for your software. Otherwise a tuner takes the job: 15 to 30 minutes during opening hours, 60 minutes at most at busy times. The estimated lead time is shown before you confirm.

Monday to Saturday, 9 am to 6 pm (Paris time). You can upload files 24/7: automatic deliveries work at any time. Outside opening hours, an on-call tuner may process some jobs between 7 am and 11 pm, with longer lead times.

Yes, always. The checksum status is shown on every delivery.

Request a revision from the job page: revisions are included for 30 days. Back-to-stock is free for any file processed by us.

The job is cancelled and the credits are returned to your account.

Each plan (Start, Sport, Turbo, Racing, Black Edition) credits your account with a number of credits valid for 30 days from purchase. Each service costs a fixed number of credits (a car Stage 1 = 12 credits), whatever the model.

From €135 excl. VAT with the Start plan down to about €54 excl. VAT with the Black Edition plan. Once your account is approved, the margin simulator in your professional area calculates what you earn from your selling price.

Take a new plan, whichever you want: it runs for another 30 days. Credits that expire first are always used first.

No. Plan credits expire 30 days after purchase.

No. The plan renews every month by card payment; change plan or stop the renewal in one click from your account, free of charge. You can also buy one month without renewal.

Yes, at any time. The new plan starts immediately for 30 days; credits you already have remain valid until their own expiry date.

Your manual jobs are processed before normal-priority jobs, at no extra credit.

Open your professional account, choose your plan, then fill in the application form on the Agents page. We call you to get to know you.

Careful work and respect for the M-AutoPerf.com charter and the law: written information for every customer, a signed document before any work, and no advertising for the removal of emission control devices.

Yes, all our prices exclude VAT. French VAT of 20 % is added for companies established in France, including sole traders. EU companies with a valid VAT number are invoiced without VAT (reverse charge); outside the EU, French VAT does not apply.

In your account, under Orders and invoices. Every purchase and every renewal generates an invoice.

Files are supplied to professionals only, as a technical service. The professional who works on the vehicle is solely responsible for the installation, for informing their customer and for complying with the regulations of their country.

Check the vehicle's condition (diagnostics, fault codes, maintenance), save the original read, inform the customer in writing of the consequences of the work and have them sign an information and consent document before any modification. A ready-to-print template is available in your professional area, under Client documents.

In particular: possible loss of the manufacturer warranty; obligation to declare the modification to their insurer; possible non-compliance of the vehicle with its type approval and registration certificate if driven on public roads; increased wear of some parts (clutch, gearbox, turbo…); the indicative nature of the stated gains; the possibility of returning to stock.

It depends on the country: rules on type approval, emissions, road safety and roadworthiness testing are specific to each one, and some services may be prohibited on a vehicle used on public roads. Before any work, the agent checks the applicable regulations, informs the customer in writing and has them sign the information document. M-AutoPerf.com supplies files to professionals and is responsible neither for their installation nor for their use.

The information document signed by the customer, the original read, the repair order and the invoice for the work. They protect you in the event of a dispute, an inspection or a claim.

Yes. We may refuse a job or suspend an account in the event of use contrary to the law or to our terms and conditions.
