Secondary injectors

[wscycle]

When(RPM) the secondary injectors start working? I want to know to set my bike with a reflash using my PC5 existing map. And did i have to cut in half or to zero the % of the PC5 parameters when the secondary injectors start,because the commander only control 4 injectors and the reflash control all 8 injectors.

I'm sure somebody will be along to tell you. You may want to PM boost by smith also. He seems to be the man when it comes to flashing ECUs here.

upper dont do anything until at least 40% throttle, at least 5600 rpm, and even at those throttle positions lowers are still doing almost all of the work.

see chart below

if you have a PC map on upper injectors only, I would recommend you start over on a dyno and tune everything properly.
