Knock Retard and Ignition Timing
What an EA888 log can show about ignition behavior, and where inference must stop.
Use time windows
A transient value needs surrounding RPM, load, temperature, and cylinder context. Repetition and operating conditions matter.
Treat protection as safety data
Do not chase a number with more load. Stop if the vehicle behaves abnormally and verify with appropriate diagnostic procedure.
