Failsafe/Startup Activation Option for Custom Maps

Fail-safe map: Select the “Map is initially inactive” option and configure the map to activate in the error condition. Once triggered, the fail-safe map will remain active until the engine is stopped. This could be a map with drop in fuel pressure relative to engine speed which could save an engine from total destruction and an expensive re-build.
Startup map: Select the “Map is initially active” option and then configure the map to deactivate when a certain condition is reached. Once deactivated, the map will not re-activate until the engine is stopped. This could be a cold start correction that is only active until a certain temperature is reached.

The Short Term Fuel Trim, Fuel Level, and Engine Oil Pressure inputs are potentially useful for building fail-safe maps.
