overboost condition. Two cut limits are configurable and the system will select the resultant
lowest boost cut MAP value.

Max Boost Limit:
A 100% fuel cut will be activated if manifold pressure in [kPa] exceeds this value regardless of
the target boost value.

Overboost Allowed:
Useful for multi fuel setups where the user has a varying boost target that depends on ethanol
content. The fuel cut will be dynamic and dependent on the target boost.

Cut activated at a manifold pressure value of: BoostTarget [kPa] + Overboost Allowed [kPa]

Oil Pressure Protection Basic Setup
The oil pressure protection strategy uses the following options along with the
OilPressProtectTable. This is typically used to activate a light, buzzer, etc.

Oil Pressure Protection Enable:
Enable and disables the oil pressure protection feature

Oil Pressure Protection Activation Delay:
Conditions must be present for this amount of time before protection function activates

Oil Pressure Protection Rev Limit:
Target RPM limit while oil pressure protection active

Lean Protection Basic Setup
The lean protection basic strategy uses the following conditions to cut fuel and/or spark in order
to prevent the engine from getting too lean and causing detrimental problems.

Lambda 1 Protection Enable:
Enable and disables the Lambda 1 protection feature

Lambda 2 Protection Enable:
Enable and disables the Lambda 2 protection feature

Lean Protect on Sensor Error:
Enable and disables the Lean Protect if the sensor is in Error Mode.

Lean Fuel Cut Enable:
Enable and disables the Lean Fuel Cut feature

Lean Spark Cut Enable:
Enable and disables the Lean Spark Cut feature

Lean Protection Minimum Engine Speed (RPM):
Only lean conditions above this set engine speed will be monitored for the lean protection
feature.
