What the filename indicates
The Stage1 suffix identifies this file as a Stage 1 variant rather than simply the base calibration name. In automotive tuning, Stage 1 generally describes a modified engine calibration intended to alter how the engine delivers power. The filename does not specify the changes made to fuel, ignition, torque limits or other control settings.
AVT and E2 are additional labels attached to this variant. Their precise meanings and any associated features cannot be determined from the filename. The related entry 89663-06F71 identifies the calibration family but does not describe a separate stock file or establish compatibility with a particular vehicle.
