Log. Tune. Flash.
Built for BMW B38/B48/B58/S58/N63/S63 engines, MGx8 gives tuners and enthusiasts the tools to analyze engine data, modify ECU calibrations and safely read or write supported MG1 ECUs.
A complete software ecosystem for logging, calibration editing and ECU flashing.
Log.
It starts with data. MGx8 Logger records what your engine really does: live data, log analysis, road dyno and drag timing in one app.

Every value at a glance.
Choose from 50+ available channels and watch up to 40 at once, at up to 50 Hz: engine speed, boost, ignition, fuel, torque, temperatures, VANOS and more, in the units you prefer.
Replay the moment.
Put boost, rail pressure and more on the same timeline, with up to five graphs and five channels on each. Wide-open-throttle pulls are found for you, and you can export a CSV range or save a graph as a PNG.
From the road to the curve.
Turn a wide-open-throttle run into estimated engine power, wheel power and torque curves. Set vehicle mass, drivetrain loss and the conditions, and open saved pulls to see how the curve changed.
Every tenth counts.
See how a run unfolds from launch to the line, with a time for every 10 km/h step and the time and speed of each gear change. Run 0 to 100 km/h, 100 to 200 km/h or a quarter mile.
Tune.
MGx8 Tuner is a calibration editor for MG1 BIN files. Open a dump, find a map by name, edit it as a table, a curve or a 3D surface, compare it with another file and save.

Applying the built-in Tune Assistant needs a Tuner license. Get one.
Every map in a window of its own.
Table, 2D curve and 3D surface sit side by side, colored by value. Drag a point on the surface or step through a row with the keyboard. Every edit is one undo step and stays inside the limits of the definition.
Tune assistant.
Pick a stage and a fuel and Tuner lists every map it will change. Untick what you do not want, apply, and take it all back in one step if you change your mind.
Flash.
Put it on the ECU. MGx8 Flasher connects over ENET, identifies the ECU, saves a full backup and writes the calibration.
Before anything is written, MGx8 Flasher validates the file, corrects checksums, checks battery voltage, verifies the ECU identity and confirms that a valid backup is available. Every flashing session is recorded in a journal.

Questions
Which cars are supported?
See the current supported vehicle list below. Compatibility can depend on the exact engine, ECU and vehicle configuration.
Is there a free version?
All apps are free except for the MGx8 Flasher.
Does it work with MHD?
Yes. An MHD tune does not affect MGx8 compatibility on a supported vehicle.
Does it work with xHP?
Yes. An xHP transmission tune does not affect MGx8 compatibility on a supported vehicle.
Do I need internet?
Internet connection is required for activation, license checks and updates.
Can I use a normal ENET cable?
Yes. A standard ENET cable connects your Windows laptop directly to a supported vehicle.
What happens if I change my laptop?
Install MGx8 on the new laptop and activate it with your license key. A Single VIN license stays tied to the vehicle, not the laptop. Unlimited VIN licenses are bound to one computer; contact us to move one.
Which files does Tuner open?
Full or partial BIN dumps of supported BMW MG1 (and MEVD17) ECUs.
Does Tuner write to the ECU?
No. Tuner edits calibration data in a file and does not write to the ECU or correct checksums. To put a calibration on the ECU, use MGx8 Flasher, and always check the result before you flash.
Can I back up my ECU first?
Yes, and it's recommended. Backup Full reads the validated memory layout into a BIN.
Which ECUs can Flasher write?
Flasher identifies MG1 ECUs and writes calibration on supported variants. Support depends on the exact ECU and software and grows with every release. Email us if you are unsure about yours.
