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.
Stage 1 vs Stage 2 — what each needs
Stage 1 runs entirely on factory hardware — no supporting mods required — and also supports cars with an upgraded intake and improved cooling. Stage 2 requires a high-flow exhaust system; an upgraded intake and improved cooling are recommended alongside it. Each stage ships as two files calibrated separately for AKI 91 and AKI 93 fuel, plus a Stage 0 factory-power baseline — five OTS files per car, matched to your ECU software version after VIN verification in the app. European / Asian fuel grades: 95 RON → use the AKI 91 file; 98 / 100 RON → the AKI 93 file. Neither stage needs a transmission (TCU) tune — both are calibrated to run with the factory TCU.
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. Vehicle coding functions (beta) are free for OTS customers.
What's in the package
- D-Sync D1 Wi-Fi OBD dongle — included, no other hardware needed (third-party ELM327-type dongles are not supported)
- Flash & Log license (one VIN) — flashing, high-speed data logging with CSV export, DTC scanning
- OTS Mappack license — Stage 1 and Stage 2, each as an AKI 91 and an AKI 93 file, plus the Stage 0 factory-power baseline: five files, all available from day one, no need to pick one stage at checkout
- Your Mercedes factory calibration — matched to your ECU software version, so you can return to stock with one tap at any time
- Exhaust Burble Tuner (AMG models) and DTC management — independent in-app controls, included free with the Mappack
- VIN binding and ECU verification in the app are free; after activation the app shows which file to flash
What you need: a phone with the D-Sync app and access to the car's OBD port.
