littlefeck Posted May 17, 2018 Report Share Posted May 17, 2018 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.

Simon Posted May 17, 2018 Report Share Posted May 17, 2018 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.

littlefeck Posted May 18, 2018 Author Report Share Posted May 18, 2018 Thanks Simon, I will look into that. there are 3 actuators on the RX8 manifold, 2 of which are vacuum driven and controlled via solenoids. The third one is a servo motor. Quote Link to comment Share on other sites More sharing options...
