One licence. The whole platform.

The Annual plan runs on 1 computer. Annual Plus and Ultimate Plus run on 2 computers, which must belong to the same holder. Each computer is activated once with a code received by email, and one transfer is allowed per 30-day period if you change machine.

Renewal before expiry is discounted on every plan: Annual €899/year, Annual Plus €2,249/year and Ultimate Plus €3,599/year. You keep the same access and all updates for another 12 months. Renewal is not automatic: we email you the offer before expiration, and your access simply ends if you do not act on it.

Annual and Monthly include no technical support and no manual processing: no manual file processing, no manual stage, no Restore ORI. Payment, delivery and account-access questions are answered by email on every plan. Annual Plus includes support, unlimited manual file processing and one manually prepared stage file per day; automatic stages are unlimited. Ultimate Plus includes support, unlimited manual files and unlimited manually prepared stages, with processing priority. Restore ORI is manual processing, available from Annual Plus. The checksum module is automatically included in Annual Plus and Ultimate Plus; it is not included in Annual. Files that can be processed are generally handled within minutes: automatically on all licences, or by the team on plans that include manual processing. Support usually answers within minutes on Ultimate Plus, and within hours on Annual Plus under normal conditions. These usual times are indicative. The announced maximum is 48 hours on Annual Plus and 24 hours on Ultimate Plus, measured in calendar hours, 7 days a week, including weekends and public holidays, upon receipt of a complete request and a usable file. For a file-related request, this period covers both processing and the support response; the deadlines are not added together. The time required depends on the file and the work requested. For a technical question without a file, the same maximum reply time applies. Manual processing requests are submitted through Support Solution in the software. Ultimate Plus is the only plan that covers trucks, agricultural, motorbike, industrial and marine. Processing times also apply to unlimited requests.

Yes. For cars and light commercial vehicles, Annual gives you the complete automatic suite, automatic modules and solutions excluding checksum, 10 files per day and full access to Server Files, more than 246,000 original files, with regular updates. You can upgrade to Annual Plus or Ultimate Plus at any time for unlimited files, manual processing and the checksum module.

Delivery is digital. For payments made on the website through Stripe, the licence is activated after payment validation and credentials are normally emailed within minutes. For professionals paying by bank transfer, credentials are sent on the day the funds are actually received in the MasterX account. Proof that a transfer was initiated is not receipt of funds. Customers must provide a valid email address and the information needed for invoicing.

Final prices include applicable taxes. Bank transfer is available to professionals: credentials are sent on the day the funds are received. See the terms of sale.

MasterX is sold exclusively to professionals (tuning companies, garages, workshops and self-employed tuners) for the needs of their business. By ordering, you declare that you are purchasing for your business activity. See the terms of sale.

Yes, and you should. The full supported list is public and searchable on the supported ECUs page, with every solution shown per ECU. Each function’s availability depends on the ECU, software version and loaded file.
