The engine control module uses sensor information and calibration data to regulate functions such as fuel delivery, ignition timing and emissions control. These controls affect engine response, fuel consumption and exhaust emissions during normal driving.
The filename identifies the 89663-0E430 calibration and carries a -B suffix. The catalog entry does not establish what that suffix denotes or identify a specific change made by this file. It should not be treated as evidence of a modified tune or a particular service revision.
