What the controller does
An engine control module uses sensor inputs to manage engine operation, including fuel delivery and ignition where applicable. Its calibration supplies the data used to make those control decisions. The complete identifier 89663-60Q60 distinguishes this catalog entry from other files in the same part-number family, but it does not establish a specific vehicle or engine application on its own.
