(1) Order the engine package for your car — every package includes the Flash & Log and OTS Mappack licenses plus the D1 Wi-Fi OBD dongle, and covers one VIN. (2) Download the D-Sync app, create an account and bind your 17-character VIN (free). (3) Plug the D1 into the OBD port; the app reads your ECU hardware/software version and verifies the car (free), then activate your licenses on that VIN. (4) Pick the Stage 1 / Stage 2 map matched to your exact ECU version and tap Flash — the app corrects the file's checksums automatically before writing (custom files included, on every supported ECU), your factory calibration is always saved, and you can revert to stock anytime with one tap.
