Key Circuit Identification
A total of 8 key circuits have been identified in the KIT33812ECUEVME. Each of these circuits has been
specifically designed to as a starting point for designing a custom electronic control unit. It is
recommended to change or validate these circuits when implementing a production ECU or a custom
design. This will produce a higher level of safety and a more cost efficient design as the
KIT33812ECUEVME was not designed to go into a specific application beyond a generic one-cylinder
engine implementation. Figure 23 identifies the key circuits in the system.
