A third-party bench unlock may be required. This software purchase does not include a separate ECU unlock service, flashing adapter or installation labor.

Digital software for one VIN. No physical item is shipped. Kies will provide license assignment/redemption instructions; contact us to confirm fulfillment timing. Do not purchase or redeem the wrong engine-family license.

App Downloads & Complete Setup Guide

Get the free MG Flasher app: iPhone / iPad · Android · Windows.

Open the full official MG Flasher user manual. Review the current instructions before connecting or flashing; the app and manufacturer instructions take precedence over this overview.

  1. Check support first. Install the app, connect a compatible ENET Wi-Fi adapter and use Check Support to identify the vehicle, DME and available products. An engine badge alone is insufficient.
  2. Arrange the correct license. Select the matching engine family. Contact Kies with your VIN and MG Flasher account information for assignment/redemption instructions. Licenses bind to one VIN; verify everything before redeeming.
  3. Resolve ECU security. Complete any required compatible unlock before flashing. Contact Kies about the method and separate cost.
  4. Prepare the vehicle. Follow the manufacturer preparation checklist, use a healthy charged battery with suitable charger, turn off electrical loads and remove incompatible piggybacks.
  5. Connect and sync. Follow the connection guide for your device. Internet is needed for support checks, account sync and map downloads; a vehicle connection is needed for flashing and logging.
  6. Flash the matching calibration. With the engine off and ignition set as instructed for your vehicle, choose the correct fuel, stage and hardware options. Do not disconnect or interrupt the process. Wait for app confirmation and follow its ignition-cycle instructions.
  7. Review the result. Check diagnostics and record logs as appropriate. Obtain tuner review when hardware, fuel or calibration requires it. Logger-only purchases do not authorize flashing.
