The FG injector cut is done in the PCM, nothing to do with the ZF.. I've turned it off on the FG's, as well as enabled it on BA/BF's for laughs.. There is 4 torque control methods used in the Ford strategies. Spark Retard Air/Fuel adjustment Injector cut Electronic throttle Large torque reductions are done with the following priority -> Injector Cut, Air/Fuel adjustment, and then Spark retard. Each one of these 4 methods can be adjusted, as well as enabled or disabled individually. **None of this is to be re-published without my permission**
