The 89663-33E60 part-number family is associated with engine control module software, which manages engine operation through functions such as fuel delivery and ignition timing. The exact vehicle application and controller are not established by this catalog entry.
What the filename identifies
The base identifier 89663-33E60 connects the file to the related calibration record. The longer filename adds B_AVT_Stage1_E2, distinguishing this file from the base entry.
Stage1 and E2 appear as variant labels, but the filename alone does not establish the changes they represent. In particular, it does not confirm which engine parameters have been modified or whether this file is a stock calibration. The label AVT is also not enough on its own to identify a specific controlled function.
