ZIPtuning (ziptuning.com) is a tuning file service for tuning companies and car workshops. Alongside custom files it offers a WinOLS reseller database, map packs and tuning tools (source). Both ZIPtuning and ECUFileMarket work with credits and an upload portal, so the useful differences are in price transparency, turnaround wording and checksum handling. Here they are, with sources.
