Interview → mic calibration → system health checks → sound-quality capture → emailed owner report.
No diagnostics without a calibrated mic. Calibrate right here — takes about a minute.
Runs the same listening battery the auto-tune preflight uses (33 checks). No DSP connected? Tests that need one are skipped honestly — everything mic-based still runs. Connect the audio source (Bluetooth/aux) to the bike first.
Ambient first (quiet), then the scored capture. Judged with the exact TL SEMS scoring engine.
