What the controller family does
An engine control module uses sensor information to manage functions such as fuel delivery and ignition timing. Depending on the vehicle, its software can also coordinate engine operation with other powertrain systems. The available catalog identifier does not establish which functions this particular calibration controls or changes.
The -B suffix and (2) in the filename distinguish this file in the catalog. They do not, by themselves, establish whether it is a stock or modified version, identify a vehicle application, or describe a revision.
