Abstract
A method for performance tuning an electronic control unit (ECU). The performance tuning may include determining one or more tunable values stored on a tunable implementation memory of the ECU to specify tunable calibration data for one or more tunable calibration parameters selected for performance tuning and controlling an application software of the ECU to execute according to the tunable calibration data.

A method for performance tuning an electronic control unit (ECU) comprising:
- determining one or more tunable values stored on a tunable implementation memory of the ECU, the tunable values specifying tunable calibration data for performance tuning;
- determining the tunable values to be one of valid and invalid;
- determining a granular security control adjustment authorization ticket (G-SCAAT) stored on the ECU to be one of valid and invalid;
- controlling an application software of the ECU to execute according to the tunable calibration data stored on the tunable implementation memory if both of the tunable values and the G-SCAAT are valid;
- and
- controlling the application software to execute independently of the tunable calibration data according to factory calibration data stored on a calibration memory of the ECU if either one of the tunable values and the G-SCAAT are invalid.
A method for performance tuning an electronic control unit (ECU) comprising:
- determining one or more tunable values stored on a tunable implementation memory of the ECU;
- determining the tunable values to be valid if within limits specified in a tunable constraint memory of the ECU, or else determining the tunable values to be invalid;
- and
- controlling an application software of the ECU to execute according to the tunable values if the tunable values are valid, or else controlling the application software to execute independently of the tunable values according to factory values stored on a calibration memory of the ECU.
A method for performance tuning an electronic control unit (ECU) comprising:
- selecting one or more partitions of a tunable implementation memory of the ECU to receive tunable values for performance tuning, the partitions being selected according to entitlements specified in a granular security control adjustment authorization ticket (G-SCAAT) installed on the ECU;
- and
- controlling an application software of the ECU to execute according to the tunable values if both of the tunable values and the G-SCAAT are valid, otherwise controlling the application software to execute independently of the tunable values.
