Safety shutdown (Emergency mode)
If any of the safety parameters are exceeded, the antilag function will end early and require the user to release the throttle before resuming regular operations. Antilag will be disabled until the safety margins are within bounds again and the user releases the throttle. Emergency mode temporarily enables “Limp Mode” to reduce exhaust gas temperatures (EGT) and relieve boost pressure (opens electronic wastegate).
You can log the parameter “Custom Code: Antilag Shutdown Reason”, or CC_ASR for short, to see the cause for the last shutdown event. Value resets to zero upon entering next antilag event.
Safety shutdown is engaged when:
Engine coolant temperature (Tmot) is out of bounds: “Coolant temperature min” (CC_ASR bit 0) and “Coolant temperature max” (CC_ASR bit 1).
Exhaust gas temperature (EGT) before turbo (Tabg_vl_xab) is greater than “Exhaust gas temperature max” (CC_ASR bit 2).
Intake air temperature (tans_msg) is greater than “Intake air temperature max“ (CC_ASR bit 3)
Intake manifold boost pressure (Ps) is greater than “Boost pressure setpoint” + “Over boost limiter“ (CC_ASR bit 4)
