I will analyze can bus logs and investigate automotive ecu issues
Over deze dienst
Having an automotive CAN log but not sure what happened?
I provide automotive CAN bus log analysis to identify abnormal signal behavior, ECU communication issues and important events in vehicle data.
I work with BLF, ASC, MDF/MF4, CSV and other CAN log formats.
What I can help with:
CAN log investigation
ECU communication analysis
Signal behavior & event analysis
Multi-signal correlation
Normal vs abnormal log comparison
DBC-based signal decoding
CAN log conversion & merging
Signal visualization & plots
Technical findings & recommended checks
Typical use cases:
Vehicle or ECU communication issues
Unexpected signal behavior
EV/BMS/charging investigation
VCU/powertrain events
Thermal-management events
CAN communication troubleshooting
Supported data:
BLF | ASC | MDF/MF4 | CSV
A DBC file is recommended for signal-level decoding. If unavailable, I can still review raw CAN data or already-decoded measurement data depending on the request.
Please do not send confidential OEM information you are not authorized to share.
For best results, provide the log file, DBC if available, signals of interest, and a brief description of the expected vs actual behavior.

Veelgestelde vragen
What CAN log formats can you analyze?
I can work with BLF, ASC, MDF/MF4 and CSV logs. I can also decode, visualize, convert and process CAN data depending on the available files and your requirements
Do I need to provide a DBC file?
A DBC is helpful but not always required. I can analyze decoded MDF/MF4 or CSV signal data without a DBC. For raw CAN logs, a DBC or signal definition is recommended. If unavailable, please contact me first to check what analysis is possible
Can you find the root cause of my vehicle or ECU issue?
I can identify abnormal signals, event sequences and possible causes supported by the provided data. Final root-cause confirmation may require ECU software, calibration, specifications or additional measurements
Can you analyze large or complex CAN logs?
Yes. Please contact me before ordering if you have large logs, multiple CAN channels or DBC files, or want to investigate multiple issues so I can confirm the scope.
Can you convert or merge CAN log files?
Yes. I can support CAN log conversion, decoded signal export and BLF merging. Please contact me with the source format, desired output format and number of files.
