★★☆☆☆ (2/5 – functional but risky and obsolete for 2020+ vehicles)

1. Overview & Purpose DFT Pro (Diesel Flash Tool Pro) V3.9.7 is a software application designed for reading, writing, and editing calibration files (tunes) on diesel engine control units (ECUs). It is not an official dealer-level tool but rather a third-party solution popular among tuners, repair shops, and experienced enthusiasts working with Bosch EDC (Electronic Diesel Control) systems, particularly on vehicles from BMW, Mercedes-Benz, Audi/VW, PSA (Peugeot/Citroën), and Ford.
