Reading the catalog identifier
The filename contains the identifier 899834810300 and the suffix (1). That suffix is part of the catalog filename and does not, by itself, identify a stock or modified calibration. No named variant or documented change is associated with this entry.
Confirming the firmware’s role would require a matching controller record, vehicle application, or service documentation that identifies the complete calibration.
