What the filename identifies
The complete calibration identifier distinguishes this entry from other Toyota software records. The suffix _AVT_Stage1_E2 is a variant label attached to this particular file. “Stage1” suggests a modified calibration, but the label alone does not establish which engine settings were changed or what “AVT” and “E2” mean.
An engine control module generally manages fuel delivery, ignition and other engine operating functions using sensor inputs. That describes the controller family, not a confirmed change made by this file. The catalog entry does not identify a stock counterpart, a specific vehicle application or a documented revision history.
