Staged tertiary injector

Recommended Posts

I'm looking at setting up a link xtreme ECU on a Mazda RX8. This is a 2 rotor engine and stock has 3 injectors per rotor for 6 total. the second and third injectors do not operate until appropriate intake valves in the manifold have opened (secondary valve opens at approx 4k rpm and the tertiary opens at approx 6krpm).

Is it possible to set up staged tertiary injection (I can only see options for secondary injection) or would it be easier  just to run a larger secondary and drop the third injector.

You can use aux injection control to give you effective tertiary control. However on the stock RX8 manifold the bigger issue is controlling the opening of the valves as they are not a not solenoid controlled I'm led to believe.
