I bought an xcessive lower intake manifold for my 3 rotor. It has 6 secondary injector ports. I am running 900cc FIC injectors for primaries and 6x 900cc FIC injectors for the secondaries. I'm running microtech LT16 to control the injectors.

my first question is: do you think I should run a "third stage" for the 3 additional secondary injectors or just run it in "batches" of 2?

I think I read it correctly that LT16 can not control 9 injectors individually, so I must batch 2 injectors per driver for the secondary injectors. I only saw 2 additional wires for AUX INJECTORS (#1 & #2) in the microtech wiring diagram. I assume these two wires are for third and fourth staging? I can't find any wiring help to set up a third stage.

I tried to draw the wiring for these secondary injectors for the batch control. I would appreciate if someone can chime in before I started splicing the wires. Thanks!

I like the idea of batch to simplify tuning. I'm going for 500whp with gt42, nothing too crazy.

 

The way you wired it is correct.
