How flashing works
Every tune is flashed over the OBD port from your phone: plug in the D-Sync D1 Wi-Fi dongle, open the D-Sync app, pick Stage 1 or Stage 2, and flash. No laptop, no bench, no shipping your ECU. Your factory calibration is saved automatically — revert to stock with one tap, anytime.
Included with the OTS Mappack
DTC management during flash — select fault codes to manage right in the app before flashing (intended for closed-course use; vehicles on public roads must comply with local emissions regulations). Exhaust Burble Tuner (AMG models only) — adjustable pops & bangs with 13 in-app controls, included at no extra cost with every OTS Mappack purchase. Live data logging is part of the Flash & Log license.
