Self-install ECU/TCU flashing device that lets the owner load 034Motorsport's Dynamic+ performance software onto their own car - switch performance stages, apply factory-conservative or aggressive maps, pull software updates, or revert to stock - without a shop visit. The kit includes an OBD-II adapter, USB cables, a carrying case and user login credentials, and pairs with the 034SPI mobile app (iOS / Android / Apple Silicon Mac) to flash the car, adjust fuel maps, configure live data/gauge displays, record and submit datalogs, and read or clear diagnostic trouble codes.

Fitment: Audi and Volkswagen models on the EA888 Gen2/Gen3 2.0T FSI/TFSI, EA113 2.0T FSI, EA839 3.0T/2.9T TFSI and EA855 2.5T TFSI EVO engine families - covers the A4, A5, S3 and S4 (B8/B8.5) and Golf R (MK7) with automatic, manual or DSG transmissions. This is the flashing hardware only; the performance tune itself is licensed separately.
