Abstract
An electronic control unit (ECU) includes a microcontroller, a first non-volatile memory bank, a second non-volatile memory bank and a volatile memory. The microcontroller is coupled to an external tool and executes a control algorithm, which controls a subsystem coupled to the ECU. The first non-volatile memory bank is coupled to the microcontroller and initially stores a plurality of initial calibration tables. The second non-volatile memory bank and the volatile memory are also coupled to the microcontroller. The microcontroller executes code, which calibrates the ECU without interrupting the normal operation of the subsystem.
