I'm converting a REPU to a GM TBI throttle body and I am going to us the below settings. Were it says "Staged injection = on" Can I use the OFF setting or are there other things it will affect? There are only 2 large injectors and no secondary injectors.

RX8 2 rotor

The FD engine uses a individual logic wasted spark coils for leading spark on both rotors and individual logic coils for trailing ignition. Settings:
Engine stroke = rotary
Rotors = 2
Injectors = 2
Fuel hardware = MS3X
Number of coils = coil on plug
Rotary trailing mode = n/a (greyed out)
Spark hardware = MS3X
Staged injection = on

Wiring:
Spk A Front Leading coilSpk B Rear Leading coilSpk C Front trailing coilSpk D Rear trailing coil
Inj A Front rotor primary injectorInj B Rear rotor primary injectorInj C Front rotor secondary injectorInj D Rear rotor secondary injector

 

If you are only using two injectors, turn staged injection off.

 

Thats what I thought Thank you for conferming.
