Lean power cut enable

Built in safety function to prevent engine from running lean.

RPM, boost pressure (MAP), TPS and lambda values can be changed to achieve the desired effect on cut level.

Use this function with precautions as it might be difficult for a driver to handle loss of power during high speed racing.


Note: Requires a wide band sensor connected to MaxxECU




Specifies the MAP value engine must exceed in order to activate this function.



Specifies the minimum RPM to activate this function.



Specifies the minimum TPS to activate this function.


Max lambda

Specifies highest lambda value to activate this function.



Soft cut enable

Enable or disable the soft cut function.

When enabled MaxxECU will "soft cut" (misfire) before completely shut down the engine.


Time before soft cut

Time before soft cut is enabled.

Should be lower than Time before cut below because lambda value needs time to stabilize.

Recommended value is 0.5 sec.



Time before cut

Specifies the time frame before MaxxECU will cut the engine completely.

Do not use to low values because lambda needs time to stabilize.

Recommended values: 0.5 - 1.0 sec.
