Rotary engines typically use a staged injection setup, in this case wire the Injectors as shown in the table below:

Rotary Staged Injection Wiring

Notes:

·A Xtreme, Fury or Storm ECU is required for sequential staged injection on 3 and 4 rotor engines.

·Injection mode should be set to Sequential/Staged.

·Ensure injector staging adjustments and primary and secondary injector dead times are is setup correctly for the injector types fitted.

·ECUs without peak and hold injection must be wired with ballast resistors if low impedance injectors are used.

·When wiring low impedance injectors directly to a peak and hold ECU, make sure Injector Driver Mode is set to Peak and Hold and the correct peak and hold currents have been set.

·Spare Injection drives can be used as additional auxiliary outputs if required.
