Engine control function
The engine control module manages functions such as fuel injection and ignition timing using sensor information and operating conditions. These controls affect starting, idle, acceleration, emissions and fuel consumption. On a 2GR-FE engine, the module also manages variable valve timing.
The identifier 89663-42E91 distinguishes this calibration from other Toyota engine control files. The catalog does not identify a particular driveability correction, bulletin revision or modified feature for this file, so its specific changes should not be inferred from the controller family alone.
