A method is provided for testing the evaporative emission system of a vehicle having a forced induction engine. The method includes controlling a vacuum bypass valve and a purge flow control valve to create the necessary conditions to perform the testing of the evaporative emission system. The method determines whether an evaporative system integrity monitor switch is open after a timer is initiated and the vacuum bypass valve is opened.

A flashloader having a standard module for receiving programming instructions and an application program via a communications port of a vehicle controller, where the flashloader further provides an MCU module for writing the received application program to reprogrammable memory within the vehicle controller, and an ECU module for determining whether a valid application program has been stored in the reprogrammable memory. Upon detection of a valid application program a microprocessor of the vehicle controller executes instructions from the reprogrammable memory and upon detection of an invalid application program the microprocessor continues to execute instructions from the bootloader.
