EGT Alarm

EGT function is used to indicate overrun of defined exhaust gas temperature. In the case of two
sensors it is possible to define which sensor should be used for alarm function. There is also an
option to indicate temperature overrun using check engine light. To activate this feature in options
Check Engine/Report EGT alarm should be checked.
