Slave file management: the right encrypted file for every customer tool
In a tuning file service, customers with slave tools can only use files encrypted for them. Sending a plain read by mistake costs time and trust. TuningFile knows which customer is a slave, handles each format, and stops the wrong delivery.

What goes wrong without it
- You tune the file, forget to encrypt it, and the customer cannot load it.
- You are not sure whether a customer is a master or a slave, so you guess.
- Every tool has its own format and its own encrypt step, to repeat by hand.
What TuningFile does
- Master/slave check. For Magic Motorsport Flex it reads the slave list from your account, matches each customer by e-mail or name, remembers the result and lets you re-check it on demand.
- Right format per tool. MMS (.mmf), Dimsport TFP (.tfp) and FPO (.fpf), Alientech (.cod) and Autotuner, each encrypted through its own automatic step.
- Guard against plain reads. If you try to deliver what looks like an unencrypted read to a slave customer, the platform stops you and tells you to encrypt it first.
- Masters handled properly. A Flex master customer rewrites the read with their own licence, so for them a plain file is allowed.
Also: slave accounts as sub-dealers
If you sell through other workshops, each can have its own account with its own credit balance and pricing. The platform handles onboarding, per-account pricing and invoicing. Read the guide Master vs Slave in chiptuning.

Frequently asked questions
What is a slave tool in chiptuning?
A tool locked to files supplied by a file service. It only accepts files encrypted for it, so the service must deliver the encrypted file, not the plain read.
How does TuningFile know if a customer is a slave?
For Magic Motorsport Flex it checks the slave list of your account and matches the customer by e-mail or name, and you can re-check it at any time.
What if I deliver a plain read by mistake?
For crypt formats the platform detects it and blocks the delivery to slave customers, asking you to encrypt the file first.
