What the filename identifies
The A-TUN_E2 suffix distinguishes this file from the base catalog entry. It appears to be a variant label, but the label alone does not establish which settings were changed or whether the file is a stock or modified calibration.
The exact vehicle application and the effect of this particular revision cannot be determined reliably from the identifier alone. The engine-control association describes the part-number family’s general role, not a verified change in this file.
