Tuningfiles-server.com is a tuning file service for distributors, independent tuners and individual customers. You upload your original file to its server, and it returns a file edited from that original (source). Like ECUFileMarket, it uses credits and an online upload. The useful differences are how credits are priced, how its automatic and manual services split the working week, and how checksum handling is described. Each point below is sourced.

Which one fits your workshop?
Tuningfiles-server may suit you better if you often need files outside office hours and your ECU is likely to be in its automatic database, or you also want to buy WinOLS EVC credits from the same supplier.
ECUFileMarket may suit you if you want every file engineered to order, you’d like to see each service’s credit value before you register, and a separately charged, clearly disclosed checksum correction works for you.
