How engine dyno data moves from channel definition to a reproducible report: units, versioning, raw and filtered layers, identity records and audit trail.
How ECM and CAN data join a dynamometer record: channel mapping, time synchronization, missing-data handling and diagnostic use, with the limits stated.
How engine test cells decide safety limits, separate warning from derate and shutdown, handle sensor plausibility, and validate interlocks before testing.
How automated engine test sequences are built from set points, ramps and cycles, how interlocks behave, and where unattended testing stops.
How static dynamometer torque calibration works: lever arm and weights, zero, span, linearity and direction checks, and where errors enter the record.
