Full Answer
Atlas records selected gauges, and the useful set depends on the calibration and the question being investigated. Start with the gauge set supplied or requested by your tuner rather than a universal list.
Common context can include RPM/load, throttle, target and actual boost, commanded and measured fueling, fuel corrections, relevant knock monitors, temperatures, and diagnostic trouble codes. A value is not a diagnosis by itself; sensor validity, operating conditions, calibration definitions, and patterns across the log matter.
Review logs after the drive instead of watching a laptop while driving. If the calibration provider requests a controlled pull, follow that provider's procedure and use a private road, closed course, or dynamometer with appropriate help. Atlas's own virtual-dyno guidance warns against doing pulls on public roads and says to stop safely if knock occurs or the engine sound changes.
Keep the Atlas version and definition current, because available parameters and logging requirements change between releases.
