Min RPM Table



When the Decel Cut function has activated, normal engine operation will occur if the RPM drops below the amount in this table. Up to 3D mapping is available.

Note: RPM Derivative (rate) is used to detect how fast the RPM is falling. If at a slow rate the Decel Cut can continue to a lower RPM for smoother transition. If at a fast rate, such as free-revving, the Decel Cut will resume normal engine operation at a higher RPM value to give a smoother transition.

O2 Control also uses this table to disable closed loop above this RPM when Zero Demand conditions are met to prevent the ECU from trying to adjust the fuel when combustion is not stable.
