TCU Flash License — VGS-NAG3 (Mercedes 9-speed): $799 USD including the TCU OTS Tune, $599 USD for existing D-Sync OTS customers, one VIN per license — license only, the D1 dongle is not included. Order by email: duke@yd-autogroup.com.
CPC NG Flash License — next-generation Central Powertrain Controller: $799 USD including the CPC OTS Tune, $599 USD for existing D-Sync OTS customers, one VIN per license — license only, the D1 dongle is not included. Original CPC ECODE + EDATA files are provided for third-party tuners. A factory CPC needs a new CPC module fitted before anything is written: the app backs up the original CPC's VIN and coding, writes the D-Sync bootloader to the new module and restores the VIN and coding onto it — the original factory CPC is not rewritten in place.

Each mappack contains a Stage 0 factory-power baseline plus Stage 1 and Stage 2 OTS files calibrated separately for AKI 91 and AKI 93 fuel (five files per car), plus two independent app controls: the Exhaust Burble Tuner (AMG models, included free) and DTC management (intended for closed-course use; vehicles on public roads must comply with local emissions regulations). The exact file list is matched to the car's ECU software version after VIN verification.
