Open my accountFrequently asked questions
How does the MFT Dev Files Service work?
You create a request from your garage account: number plate, ECU read and services. An MFT Dev engineer writes a custom file and sends it back encoded for your tool. You follow every step live.
How long does it take to get a file?
Usually a few minutes during our opening hours, Monday to Saturday. The usual turnaround, measured on our requests, is shown live at the top of this page.
Which reading tools are supported?
Alientech KESS3, K-TAG and KESSv2 and Autotuner, master or slave, with automatic decoding and encoding. More than 30 other tools are accepted as master reads.
Which language do I use with the engineer?
Your own: English, French or Spanish. Your messages are automatically translated for the engineer, and the replies reach you in your language.
How much does a remap cost?
Each service has a price in credits, shown before you send. Credits are bought by card from your account. Examples: Stage 1 car €70, Stage 1 truck €105.
What if the file is not right?
Request a revision from the request page, free during the after-sales period: the engineer picks the job back up with the full history. Back to stock is always possible, free of charge.
A vehicle has a problem, remapped or not: what should I do?
Open Diag Expert from your account, or from the request for one of our remaps, and send the log: it finds the cause and gives you the checks in order. Free on your remaps during the after-sales period, 1 credit for any other vehicle, even one never remapped.
Is sign-up free?
Yes. Sign-up is free with no commitment. Your account is activated by our team, then you only pay for the files you order.
Ready to send your first file?
Create your garage account in two minutes. Our engineers take care of the rest.
Some services, especially those that modify emission control systems, may be prohibited depending on your country and how the vehicle is used. You are responsible for the compliance of the files you use.
