 # Boost pressure limit

+## Boost cut pressure
+
+This setting defines the upper limit of pressure the engine will operate within. If the engine's MAP reading exceeds the value configured in __Boost cut pressure__, FOME will cut fuel injection until the MAP reading falls 20kPa below the configured value. The 20kPa hysteresis value is hard-coded.
+
+This value is absolute pressure, so if an engine is running 7 PSIG of boost pressure (~148kPa absolute), this value would need to be set above 150kPa. It is a good idea to allow enough of a margin to prevent unnecessary boost cut on small excursions above the target boost pressure.
+
+Set this value to 0 to disable the boost cut limit.

 # Rev limiters

 ## Hard cuts  
 
+![image](RPM-Limit/revLimitHardCuts.png)
+
+Hard cuts apply when an engine reaches the _RPM hard limit_. In most cases, it is recommended to use fuel cut instead of spark cut.
+
 ### Fuel cut  
 
+If _Cut fuel on RPM limit_ is set to __yes__, FOME will stop injecting fuel once the engine reaches the _RPM hard limit_. The engine speed must drop below the _RPM hard limit_ by the number of RPM specified in _Hard limit hysteresis_ before fuel injection is resumed.
+
 ### Spark cut  
 
-### Both cut 
+If _Cut spark on RPM limit_ is set to __yes__, FOME will stop firing the ignition coil(s) once the engine reaches the _RPM hard limit_. The engine speed must drop below the _RPM hard limit_ by the number of RPM specified in _Hard limit hysteresis_ before ignition is resumed.
+
+:::danger  
+
+If _Cut fuel on RPM limit_ is set to __no__ then fuel will continue to be injected during the spark cut. This can cause a build-up of unburned fuel in the exhaust system which may ignite when ignition resumes and can cause damage to the engine and exhaust system.
+
+:::
+
+:::warning
+
+Cutting spark can lead to engine valvetrain damage due to the immediate reduction in torque. It is recommended to use fuel cut instead of spark cut in most cases.
+
+:::
+
+### Both cut  
+
+Both fuel cut and spark cut can be used together. This reduces the risk of unburned fuel in the exhaust when using spark cut, but the risk of valvetrain damage still applies.

+### Electronic Throttle Limiting  
+

-## Soft limiting 
+Engines equipped with an Electronic Throttle Body (ETB) can utilize Electronic Throttle Limiting. This will smoothly close the throttle starting at the _Soft limiter start_ engine speed and fully close it once the engine speed has increased by the number of RPM defined in _Soft limiter range_.
 
-### ETB soft limit  
\ No newline at end of file
+For example, if _Soft limiter start_ is 6000 RPM and _Soft limiter range_ is 200 RPM, the maximum ETB position possible at 6100 RPM is 50%, and at 6200 RPM the electronic throttle will be fully closed even if the accelerator pedal is commanding a larger opening.
