MG Flasher Logger
Record. Review. Share.

Overview
Capture the Complete Event.
Datalogging records selected supported parameters continuously during a session. Instead of viewing only one moment, the resulting log shows how values changed over time and how different systems behaved together.
This makes datalogging useful for tuning review, controlled troubleshooting and comparing vehicle behaviour before and after a change. Available parameters depend on the vehicle, ECU software, app version and installed Custom Code.
A Datalog Can Help You
01
Review a Full SessionAnalyse the event instead of relying on a single live value.
02
Compare ParametersSee how boost, fueling, timing and temperatures changed together.
03

Monitoring vs Recording
Live Data Now. A Complete Log Later.
Live Monitoring and Datalogging use related data, but they answer different questions.
Record the Whole Session
- Captures selected parameters over time
- Useful for detailed analysis after the event
- Helps compare multiple values and sessions
- Can be exported for tuning or diagnostics
Recorded Data
Build a Log Around the Question You Need to Answer.
Parameter availability varies by vehicle. The categories below describe common logging groups and do not guarantee that every value is available on every platform.
Boost and Engine Load
Record supported pressure, load-request and air-path values across the session.
Lambda and Fuel Data
Review selected lambda, fuel-pressure and fueling-related parameters where available.
Temperatures
Track supported coolant, intake-air and other thermal values throughout the event.
Ignition and Corrections
Analyse supported timing, correction and combustion-related data over time.
Torque, RPM and Throttle
Compare supported engine-speed, torque-request and driver-input values.
Feature and Protection Data
Compatible Custom Code can add feature status, validity and shutdown-reason parameters.
Logging Workflow
From Vehicle Connection to Exportable Log.
Plan the session first, then record only the data needed for the tuning or diagnostic question.
Connect to the Vehicle
Use a supported ENET connection and open the vehicle in MG Flasher.
Select Relevant Parameters
Choose the available values needed for the specific review instead of recording everything without a purpose.
Start the Logging Session
Record the event under controlled conditions while following safe operating procedures.
Stop and Analyse
Review how selected values changed together and note the conditions surrounding the event.
Export the Log
Share the recorded session with your tuner or support specialist when further review is required.
Desktop ReviewDownload MG Flasher
More Screen Space for Detailed Analysis.
The Windows version of MG Flasher provides a larger workspace for reviewing logger data and comparing parameters. Mobile remains useful for in-car recording, while desktop offers more room for structured review and troubleshooting.
Mobile RecordingCompact workflow for connecting and recording a supported vehicle.
Desktop ReviewLarger interface for clearer parameter visibility and session analysis.
Exportable DataShare recorded information when working with a tuner or support team.
Use Cases
Better Evidence for Tuning and Troubleshooting.
A useful log begins with a clear question and enough context to interpret the recorded values correctly.
Tuning Review
Record a controlled session so a tuner can evaluate how the calibration behaves under the selected conditions.
Troubleshooting
Capture the operating conditions around an issue instead of relying only on a verbal description.
Before-and-After Comparison
Compare similar sessions after a map, hardware or configuration change.
Custom Code Analysis
Record supported feature, validity, protection and shutdown-reason parameters where available.
Good Logging Practice
Record Safely and Keep the Context.
A log is only useful when the test is safe, controlled and documented clearly enough to interpret later.
Use a Safe Environment
Do not interact with the app while driving. Use an appropriate controlled environment and a second person where necessary.
Select Relevant Values
Choose parameters that answer the actual tuning or diagnostic question and avoid unnecessary clutter.
Note the Conditions
Record fuel, map, hardware, gear, temperatures and any other context needed to interpret the session.
Repeat Consistently
For comparisons, use similar test conditions so differences are more meaningful.
Compatibility
Available Parameters Depend on the Complete Setup.
The logger can only record values exposed by the connected vehicle, ECU software and installed configuration.
Supported Vehicle
The engine, ECU and software must communicate correctly with MG Flasher.
Vehicle Connection
A supported ENET connection is required while recording vehicle data.
Available Parameters
The exact list varies by engine platform, ECU software, sensors and Custom Code version.
Correct Interpretation
Recorded values must be reviewed in the context of the vehicle, map, hardware and test conditions.
Connection note:
A direct car connection is required for logging. Internet access may be needed separately for account syncing,
uploading or sharing files depending on the workflow.
FAQ
MG Flasher Datalogging FAQ.
Common questions about recording, reviewing and sharing BMW vehicle data with MG Flasher.
What is BMW datalogging?
Datalogging records selected supported vehicle and ECU parameters continuously over a period of time so the complete session can be reviewed afterward.
How is datalogging different from Live Monitoring?
Live Monitoring shows current values while connected. Datalogging records those values over time for later analysis, comparison or sharing.
Which parameters can MG Flasher record?
The available list depends on the engine, ECU software, installed sensors, app version and Custom Code configuration. Common categories include boost, fueling, temperatures, ignition, torque and feature-specific data.
Can I share a datalog with my tuner?
MG Flasher describes Vehicle Logging as providing exportable logs for tuning and diagnostics. Share the log together with the relevant vehicle, fuel, map and test-condition information.
Do I need to stay connected to the vehicle while logging?
Yes. A direct supported vehicle connection is required while recording live ECU and vehicle data.
Can I review logs on Windows?
MG Flasher is available on supported Windows devices, and the larger desktop interface provides more screen space for detailed logger review and troubleshooting.
Does a datalog automatically diagnose a problem?
No. A datalog provides recorded evidence, but correct interpretation still depends on the vehicle, calibration, hardware, conditions and the question being investigated.
Is it safe to operate the logger while driving?
Do not interact with the app while driving. Plan the session, use a safe controlled environment and involve a second person when interaction with the device is necessary.
