01 / GUIDE
Define the question first
State the symptom, the operating condition and the time at which it occurs. Decide whether the log is intended for startup review, intermittent faults or a planned calibration session.
02 / GUIDE
Choose channels for the question
Agree the required measurements and status channels with the reviewer. Logging every available value may add volume without improving the answer to the specific question.
03 / GUIDE
Confirm logger capability
Check whether the exact ECU supports the required on-device or computer-based logging. Confirm storage, trigger conditions and export options using the matching software documentation.
04 / GUIDE
Send context with the file
Include units, calibration version, device identity and a short event timeline with the log. Our homepage curves are demonstration graphics, not measured customer results.
