Quantum Tuning is a UK remapping company that runs a dealer network and a tuning file service for dealers and for tuners who already own a tool (source; source). ECUFileMarket is a credit-based custom file service open to any workshop that registers. If you’re weighing the two, the main differences are the dealer model, how prices are shown and opening hours.

Dealer network vs open file service
Quantum’s file service is closely tied to its dealer programme. The vendor states it has more than 1,000 dealers in over 95 countries (source). Its dealer page describes dealer file plans where “the more you buy the cheaper they are”. File costs are shown when you sign up, credits for tool buyers come in bundles of 6, 14 or 25, and single files are available for occasional users (source). The same page also describes a white-label option, where Quantum supplies files confidentially to other companies (source). Tuners who already own a tool can open an account for 24/7 file access with instant activation (source).
ECUFileMarket has no dealer programme. Any workshop can register, buy credits and upload a file. Prices in credits are shown after you log in. See our pricing page.
