Choose a professionally prepared MG Flasher calibration for your supported vehicle, fuel and hardware setup. Available OTS stages and power levels depend on the engine platform, ECU software and selected map package.

OTS means Off-The-Shelf. Each MG Flasher OTS map is prepared for a defined engine platform, stage, fuel quality and supported hardware configuration. The app displays only the maps available for the connected vehicle and ECU software.
OTS maps are intended for repeatable, clearly defined setups. They are different from Custom Flash files, which are created individually by an independent tuner around a specific vehicle and modification list.
Engine PlatformThe calibration must match the supported engine and ECU generation.
Stage & HardwareThe required hardware depends on the selected performance stage.
Fuel QualitySelect the calibration intended for the fuel actually used in the vehicle.
Stage availability, output and hardware requirements vary by engine, generation, fuel and map version.
Designed for supported vehicles using compatible factory or near-stock hardware. Stage 1 focuses on improving performance while retaining a smooth, usable power delivery.
Intended for supported vehicles equipped with the required less-restrictive exhaust hardware and using the correct fuel. Requirements must be confirmed for the exact platform before flashing.
Available only on selected platforms. Stage 2.5 may require an upgraded high-pressure fuel pump, compatible exhaust hardware and the correct in-app hardware selection.
Supported OTS packages may include calibrations for different octane or RON levels. The selected fuel file becomes the calibration flashed to the vehicle, so the fuel in the tank must meet the map requirement.
Some compatible OTS packages may also provide additional fuel or ethanol choices through Switchable Maps. Slot availability and contents depend on the exact map package, Custom Code version and platform.

Both options use MG Flasher, but they are built for different levels of vehicle modification and individualisation.
The app guides the user through vehicle support, licensing, map selection and flashing.
Connect the vehicle and let MG Flasher identify the ECU, software and available map stages.
A valid VIN-locked Flashing License is required before flashing an OTS map.
Select only the stage, octane level and options appropriate for the vehicle setup.
Follow the battery, ignition, connection and electrical-load requirements before starting.
Keep the connection stable, wait for success and follow the required ignition cycle.
A Flashing License activates flashing for one vehicle and is locked to its VIN. OTS maps are then purchased for that supported vehicle, either individually or as an available map package.
The license also enables diagnostics and Custom Flash. The original stock calibration is retained so the vehicle can be returned to stock through the app when required.
VIN-locked access that allows repeated flashing of the assigned supported vehicle.
Purchase an available Stage 1, Stage 2 or other supported map for the vehicle.
Where offered, one package can include all available OTS maps for the assigned VIN.
The original calibration remains available for supported stock restoration workflows.
When MG Flasher is connected to the internet, the app can synchronise available map information. If an updated file is available for a purchased map, the app can download the current version before flashing.
Release availability depends on the exact vehicle, ECU software and map package. An update for one platform does not imply that the same version exists for every other engine or generation.
Connect to the InternetAllow the app to synchronise account and map data.
Open the Available StageSelect the purchased stage and fuel file.
Download the Current FileThe app retrieves the available update before flashing.
Depending on the platform, map and Custom Code version, the flashing workflow may expose additional options.
Map availability is determined by the connected vehicle, ECU software, unlock status, hardware and fuel.
The engine platform and software version must have an available MG Flasher calibration.
The app identifies whether the DME can be activated in-app or requires an external unlock service.
Stage-specific hardware must be installed and in good operating condition before flashing.
The fuel in the tank must meet the requirement of the selected octane or ethanol calibration.
Common questions about stages, fuel, hardware, licenses and map availability.
An OTS map is a prepared calibration for a defined supported engine, ECU, stage, fuel and hardware configuration. It is selected and flashed through the MG Flasher app.
Stage 1 and Stage 2 are available on selected supported platforms, while Stage 2.5 is available only for certain engines and hardware configurations. The app shows the current options for the connected vehicle.
No. Output depends on the engine, generation, fuel, map version, hardware, vehicle condition and environmental conditions. Review the relevant Engine or Vehicle Page for platform-specific figures.
Yes. A valid VIN-locked Flashing License is required before flashing an OTS map. The OTS map or available map pack is purchased for that supported vehicle.
You can repeatedly flash maps purchased for the assigned vehicle. On compatible configurations, Switchable Maps may also provide valid On-The-Fly slots without performing a full reflash.
Yes. The original calibration is stored with license activation and remains available through the supported Stock workflow in the app.
The app synchronises available files while connected to the internet. If an update is available for a purchased map, the current file can be downloaded before flashing.
OTS maps are prepared for defined supported configurations. Custom Flash is used for a calibration created individually by an independent tuner for a specific vehicle and modification list.
Download the app, connect your vehicle and confirm the currently supported stages, fuels and unlock requirements.
